Microblaze's purpose in OpensparcT1 Xilinx design

Hi,
I would like to know what's exactly the purpose of the Microblaze in the Xilinx project with OpensparcT1? It is said that it is used for handling memory and input/output transactions, but is it a must to use the Microblaze? is it possible to overcome its use or not? isn't generally the processor that handles itself these transactions?
Thanks for answering
Regards

Using MicroBlaze allowed us to connect up automatically to the Xilinx memory controller and other peripherals. It also allowed us to debug the memory interface.
Of course, using the MicroBlaze to handle all the memory transactions in software is slow. Connecting the core directly to the memory controller and peripherals should dramatically improve the system performance. But nobody has done it yet.

  • MicroC-OS-II running on Microblaze with UARTLITE in interrupt mode not working

    Hello, 
    I am trying to write and application that uses the MicroBlaze which runs the MicroC-OS-II. I am also trying to use the UARTLITE in interrupt mode. 
    Currently I can use the UARTLITE in interrrupt mode if I run a standalone package that is without MicroC-OS-II.m
    I read the documentation attached see page 22 (Handling Interrupts). On how the OS handles interrupts but I am little confused on how to setup the UARTLITE in interrrupt mode to work with the OS.
    I know that OS_CPU_ISR() handles the interrupt but how do I make it so that it handles the uartlite interrupt. 
    I am really confused how I should modify the UARTLITE interrupt code below to work with MICROC/OS. As really confused I MEAN I JUST DON"T understand.

    I need to set up an expense form so that our consultant can "filter" by customer type, program type, and finally the purpose of the trip. For instance: the customer types are churches, schools, organizations. The program type would be dependent on the customer type selection from the first list. Some examples would be: fund raising, gift planning, surveys, and others. The purpose of the trip would be dependent on the program type selected from the second list. Some examples of trip purposes would be: presentation, design, prospecting. Further, the purpose of trip selection from the third drop-down box would then have to determine the values of other fields by expense type: such as commission, airfare, hotel. etc. I've tried pop-up menu but can't figure out how to "select" from the final popup list and have it populate a field for the purpose of the trip. I've tried to look at the JavaScript examples for dependent drop-down boxes, but can't find any that quite fit what I'm trying to accomplish. I am very new to all of this. No training in writing Javascripts - just trying to wing it. The form has to be very simple for our consultants to use, but also give our office the detail we need to process through the correct account numbers. I would appreciate any detailed step-by-step instructions - kind of a javascript for dummies type of info. HELP!

    An AcroForm is the name given to the type of PDF form that you create in Acrobat. An XFA form is the type of form that you create in LiveCycle Designer. Although they are both PDF files, they are very different structurally and have significant;y different scripting models. So pay attention to the information on AcroForms and ignore anything about XFA. Be sure to get the sample PDF forms so you can look at how it works and where the scripts are placed.
    What you want to do will require scripting, and if you don't have the experience and are unable to use the information in the tutorials to create what you want, you might consider getting someone who has experience do this for you. I'll often suggest code if I can do so quickly, but what you want requires more than a few minutes.

  • Designing contents of SLD for Third Party Systems.

    We have a requirement to Integrate around 30 non SAP applications to SAP. For this purpose how do we design the SLD, with respect to creating Products, SWCV's, TS and BS for the Third Party/Legacy applications?
    Are ther any Best Practice available for the same?
    What are the advantage and disadvantages of making only one Third party SWCV and one Business System, keeping in mind that our landscape is very dynamic (applictions changing as well as moving in and out frequently).

    Hi,
    We can define in one Product and SWCV's, we can use the one technical system also if all are belongs to same category.
    means :
    Web as ABAP -
    > For SAP applications.
    Web as JAVA -
    > For Enterprise java applications on J2EE stack.
    Third party -
    > For People soft, BAAN, JDEdwords, ...........
    Standalone Java -
    > For File system/Databse system/Mail server/HTTP server.
    SLD -
    > For Business to Business systems(i.e. its for external SLDs).
    Business system specifies the role of the technical system,If we are using the same type of data then we use  the same business system.

    Hi guys,
    Can anyone pls enlighten me when HTMLB is required?
    Currently, I'm doing configuration and customization (with WebDynPro Java in NWDS) for ESS and MSS. How does HTMLB come into this view (if it does)? i.e. do i need HTMLB when doing customization of ESS/MSS?

    Hi Zhenmin Wang,
              HTML-Business for Java provides the user with an efficient set of controls - similar to Swing/AWT. The controls are based on servlets and JSP pages.
    The HTMLB controls can be used in a DynPage or JSPDynPage in the portal as well as servlets that run on any other servlet machine.
    Purpose :
    HTMLB allows a design-oriented page layout. It is designed to overcome typical servlet problems, such as:
    ·        Visualization and business logic are not separate.
    ·        Content management consumes a lot of qualified manpower. Skills in HTML, CSS, JavaScript etc. are essential.
    ·        Development has to take care of different web clients and -versions.
    ·        Maintaining the corporate identity through out the whole application is hard to achieve.
    ·        Namespace conflicts with form elements

    How can the schema be designed in this case?
    Thanks in advance

    @rp0428
    Thanks for taking out the time to reply to this. If we talk in terms of a tree structure, in the normal scenario we would the hierarchy as described before.
    -FWDREF
    --SECTID
    ---ILLREF
    If we don't talk in terms of xml and xsd and just talk in terms of database and keys, FWDREF would be parent, SECTID would be child and ILLREF would be grandchild. Now, in case, SECTID does not appear, we would still want a key to be generated but have a default value corresponding to it so that the parent, child and grandchild relationship is mentioned.
    The whole purpose of this XSD design is to use it in ODI where this feed file will be automatically loaded into tables from the XML generated with the parent, child and grandchild relationship maintained.
    Also, I have taken a sample data set. In the actual case, the hierarchy goes upto a maximum of 20 levels.
    Thanks to everyone and anyone who takes out time for this!

  • Purge Designator (MRCPRG)

    What exactly is the purpose of the Purge Designator (MRCPRG) job?
    We currently run that job right before we load a new Forecast into the application. But nobody here is sure why we run it.
    It looks as though (according to the log file) the job deletes records from several forecasting tables. Which means that we lose any historical data when we load a new Forecast. Is that correct?
    It looks like the job is also doing one more thing. The first log message says:
    "*Updated mrp_plans*"
    What exactly is that?

  • Can't build BSP in headless 2014.2

    I have a BSP project that I want to import and generate/build headless in 2014.2.
    I imported it and the hw platform with no issues by doing:
    C:\Xilinx\SDK\2014.2\eclipse\win64.o\eclipsec.exe -vm C:\Xilinx\SDK\2014.2\tps\win64\jre\bin  -nosplash -application org.eclipse.cdt.managedbuilder.core.headlessbuild -import hw_platform -import standalone_bsp -data . -vmargs -Dorg.eclipse.cdt.core.console=org.eclipse.cdt.core.systemConsole
    I've then tried using both:
    C:\Xilinx\SDK\2014.2\eclipse\win64.o\eclipsec.exe -vm C:\Xilinx\SDK\2014.2\tps\win64\jre\bin -nosplash -application com.xilinx.sdk.sw.BspBuilder standalone_bsp -data . -vmargs -Dorg.eclipse.cdt.core.console=org.eclipse.cdt.core.systemConsole
    and:
    C:\Xilinx\SDK\2014.2\eclipse\win64.o\eclipsec.exe -vm C:\Xilinx\SDK\2014.2\tps\win64\jre\bin  -nosplash -application org.eclipse.cdt.managedbuilder.core.headlessbuild -build all -data . -vmargs -Dorg.eclipse.cdt.core.console=org.eclipse.cdt.core.systemConsole
    The former crashes with no error messages and no significant log output. The latter simply does nothing. The hw platform is an Artix7 microblaze system created in Vivado 2014.2. The .metadata/.log is attached.

    Hi,
    The new Xilinx software command-line tool is headless and based on Tcl which is available in the SDK installation. This tool provides the Tcl interactive shell and you can use all of the supported commands.
    The Xilinx software command-line tool is a scriptable command line interface to run SDK commands, XSDB commands and HSI commands. XSCT can be launched from the Start menu under Xilinx Design Tools > SDK 2015.1.
    The following user flow describes how you can use the SDK batch mode.
    1.      Start sdk batch mode using the command:
             xsct
    2.      Set the workspace (where you want to create SDK projects) using the command:
             sdk set_workspace <Workspace Path>
    3.      If you have any local repositories, set the user repository path using the command:
             sdk set_user_repo_path <Repository Path>
    4.      Create a hardware project using the command:
             sdk create_hw_project -name <hw project> -hwspec <.hdf/.xml path>
    5.      Create a BSP for the hardware project using the command:
         sdk create_bsp_project -name <bsp project name> -hwproject <hw project> -proc <processor> -os <OS Name>
    6.      Create an application project using the command:
            sdk create_app_project -name <Application Name> -hwproject <hw Project> -proc <processor> -os <Os Name> -lang <Language> -app <Application Template> -bsp <Bsp Project>
    7.      Build the projects using the command:
            sdk build_project
    8.      Clean the projects using the command:
             sdk clean_project
    You can run your Tcl script file using the xsct -source test.tcl command.
    Example test.tcl
    #!/usr/bin/tclsh
    sdk set_workspace /tmp/test1
    sdk create_hw_project -name hw_0 -hwspec system.hdf
    sdk create_bsp_project -name bsp_0 -hwproject hw_0 -proc microblaze_0 -os standalone
    sdk create_app_project -name helloworld -hwproject hw_0 -proc microblaze_0 -os standalone -lang C -app {Hello World} -bsp bsp_0
    sdk build_project -type bsp bsp_0
    sdk build_project -type app helloworld
    sdk clean_project -type bsp bsp_0
    sdk clean_project -type all
    sdk build_project -type all
    exit
    To support the XSCT feature a complete tutorial answer record #64200 is available.
    Please refer to http://www.xilinx.com/support/answers/64200.html to get complete solution.

  • Script to download source packages

    Hi there,
    I've made a Bash script "getsrc.sh" which download easily and quickly source packages from AUR or ABS (dependencies : yaourt and makepkg). The idea is just to do in one command, something we usually do in several commands (I use yaourt -G, then makepkg -o). Example :
    /home/ehmicky $ getsrc gnome-terminal
    /tmp/gnome-terminal/src/gnome-terminal-3.2.1 $ ls
    aclocal.m4 AUTHORS ChangeLog ChangeLog.pre-2-23 ChangeLog.README config.guess
    config.h.in config.sub configure configure.ac COPYING depcomp
    gnome-doc-utils.make gnome-terminal.desktop.in.in HACKING help install-sh ltmain.sh
    Makefile.am Makefile.in missing mkinstalldirs NEWS omf.make
    po README src xmldocs.make
    It's just a Bash script you need to source in your ~/.bashrc if you want to use :
    source /path/to/getsrc.sh
    I didn't package it cause I'm new to Archlinux and still uncomfortable with the packaging procedure right now.
    I'm really not sure this might be useful for anyone (it might probably be useless indeed). I guess there are already alternatives doing just the same thign, but since while googling for it, I didn't bump into them, I thought I could post this script just in case.
    Do getsrc -h for usage.
    Here is the script file :

    # GNU GENERAL PUBLIC LICENSE
    # Version 3, 29 June 2007
    # Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    # Everyone is permitted to copy and distribute verbatim copies
    # of this license document, but changing it is not allowed.
    # Preamble
    # The GNU General Public License is a free, copyleft license for
    # software and other kinds of works.
    # The licenses for most software and other practical works are designed
    # to take away your freedom to share and change the works. By contrast,
    # the GNU General Public License is intended to guarantee your freedom to
    # share and change all versions of a program--to make sure it remains free
    # software for all its users. We, the Free Software Foundation, use the
    # GNU General Public License for most of our software; it applies also to
    # any other work released this way by its authors. You can apply it to
    # your programs, too.
    # When we speak of free software, we are referring to freedom, not
    # price. Our General Public Licenses are designed to make sure that you
    # have the freedom to distribute copies of free software (and charge for
    # them if you wish), that you receive source code or can get it if you
    # want it, that you can change the software or use pieces of it in new
    # free programs, and that you know you can do these things.
    # To protect your rights, we need to prevent others from denying you
    # these rights or asking you to surrender the rights. Therefore, you have
    # certain responsibilities if you distribute copies of the software, or if
    # you modify it: responsibilities to respect the freedom of others.
    # For example, if you distribute copies of such a program, whether
    # gratis or for a fee, you must pass on to the recipients the same
    # freedoms that you received. You must make sure that they, too, receive
    # or can get the source code. And you must show them these terms so they
    # know their rights.
    # Developers that use the GNU GPL protect your rights with two steps:
    # (1) assert copyright on the software, and (2) offer you this License
    # giving you legal permission to copy, distribute and/or modify it.
    # For the developers' and authors' protection, the GPL clearly explains
    # that there is no warranty for this free software. For both users' and
    # authors' sake, the GPL requires that modified versions be marked as
    # changed, so that their problems will not be attributed erroneously to
    # authors of previous versions.
    # Some devices are designed to deny users access to install or run
    # modified versions of the software inside them, although the manufacturer
    # can do so. This is fundamentally incompatible with the aim of
    # protecting users' freedom to change the software. The systematic
    # pattern of such abuse occurs in the area of products for individuals to
    # use, which is precisely where it is most unacceptable. Therefore, we
    # have designed this version of the GPL to prohibit the practice for those
    # products. If such problems arise substantially in other domains, we
    # stand ready to extend this provision to those domains in future versions
    # of the GPL, as needed to protect the freedom of users.
    # Finally, every program is threatened constantly by software patents.
    # States should not allow patents to restrict development and use of
    # software on general-purpose computers, but in those that do, we wish to
    # avoid the special danger that patents applied to a free program could
    # make it effectively proprietary. To prevent this, the GPL assures that
    # patents cannot be used to render the program non-free.
    # The precise terms and conditions for copying, distribution and
    # modification follow.
    # TERMS AND CONDITIONS
    # 0. Definitions.
    # "This License" refers to version 3 of the GNU General Public License.
    # "Copyright" also means copyright-like laws that apply to other kinds of
    # works, such as semiconductor masks.
    # "The Program" refers to any copyrightable work licensed under this
    # License. Each licensee is addressed as "you". "Licensees" and
    # "recipients" may be individuals or organizations.
    # To "modify" a work means to copy from or adapt all or part of the work
    # in a fashion requiring copyright permission, other than the making of an
    # exact copy. The resulting work is called a "modified version" of the
    # earlier work or a work "based on" the earlier work.
    # A "covered work" means either the unmodified Program or a work based
    # on the Program.
    # To "propagate" a work means to do anything with it that, without
    # permission, would make you directly or secondarily liable for
    # infringement under applicable copyright law, except executing it on a
    # computer or modifying a private copy. Propagation includes copying,
    # distribution (with or without modification), making available to the
    # public, and in some countries other activities as well.
    # To "convey" a work means any kind of propagation that enables other
    # parties to make or receive copies. Mere interaction with a user through
    # a computer network, with no transfer of a copy, is not conveying.
    # An interactive user interface displays "Appropriate Legal Notices"
    # to the extent that it includes a convenient and prominently visible
    # feature that (1) displays an appropriate copyright notice, and (2)
    # tells the user that there is no warranty for the work (except to the
    # extent that warranties are provided), that licensees may convey the
    # work under this License, and how to view a copy of this License. If
    # the interface presents a list of user commands or options, such as a
    # menu, a prominent item in the list meets this criterion.
    # 1. Source Code.
    # The "source code" for a work means the preferred form of the work
    # for making modifications to it. "Object code" means any non-source
    # form of a work.
    # A "Standard Interface" means an interface that either is an official
    # standard defined by a recognized standards body, or, in the case of
    # interfaces specified for a particular programming language, one that
    # is widely used among developers working in that language.
    # The "System Libraries" of an executable work include anything, other
    # than the work as a whole, that (a) is included in the normal form of
    # packaging a Major Component, but which is not part of that Major
    # Component, and (b) serves only to enable use of the work with that
    # Major Component, or to implement a Standard Interface for which an
    # implementation is available to the public in source code form. A
    # "Major Component", in this context, means a major essential component
    # (kernel, window system, and so on) of the specific operating system
    # (if any) on which the executable work runs, or a compiler used to
    # produce the work, or an object code interpreter used to run it.
    # The "Corresponding Source" for a work in object code form means all
    # the source code needed to generate, install, and (for an executable
    # work) run the object code and to modify the work, including scripts to
    # control those activities. However, it does not include the work's
    # System Libraries, or general-purpose tools or generally available free
    # programs which are used unmodified in performing those activities but
    # which are not part of the work. For example, Corresponding Source
    # includes interface definition files associated with source files for
    # the work, and the source code for shared libraries and dynamically
    # linked subprograms that the work is specifically designed to require,
    # such as by intimate data communication or control flow between those
    # subprograms and other parts of the work.
    # The Corresponding Source need not include anything that users
    # can regenerate automatically from other parts of the Corresponding
    # Source.
    # The Corresponding Source for a work in source code form is that
    # same work.
    # 2. Basic Permissions.
    # All rights granted under this License are granted for the term of
    # copyright on the Program, and are irrevocable provided the stated
    # conditions are met. This License explicitly affirms your unlimited
    # permission to run the unmodified Program. The output from running a
    # covered work is covered by this License only if the output, given its
    # content, constitutes a covered work. This License acknowledges your
    # rights of fair use or other equivalent, as provided by copyright law.
    # You may make, run and propagate covered works that you do not
    # convey, without conditions so long as your license otherwise remains
    # in force. You may convey covered works to others for the sole purpose
    # of having them make modifications exclusively for you, or provide you
    # with facilities for running those works, provided that you comply with
    # the terms of this License in conveying all material for which you do
    # not control copyright. Those thus making or running the covered works
    # for you must do so exclusively on your behalf, under your direction
    # and control, on terms that prohibit them from making any copies of
    # your copyrighted material outside their relationship with you.
    # Conveying under any other circumstances is permitted solely under
    # the conditions stated below. Sublicensing is not allowed; section 10
    # makes it unnecessary.
    # 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    # No covered work shall be deemed part of an effective technological
    # measure under any applicable law fulfilling obligations under article
    # 11 of the WIPO copyright treaty adopted on 20 December 1996, or
    # similar laws prohibiting or restricting circumvention of such
    # measures.
    # When you convey a covered work, you waive any legal power to forbid
    # circumvention of technological measures to the extent such circumvention
    # is effected by exercising rights under this License with respect to
    # the covered work, and you disclaim any intention to limit operation or
    # modification of the work as a means of enforcing, against the work's
    # users, your or third parties' legal rights to forbid circumvention of
    # technological measures.
    # 4. Conveying Verbatim Copies.
    # You may convey verbatim copies of the Program's source code as you
    # receive it, in any medium, provided that you conspicuously and
    # appropriately publish on each copy an appropriate copyright notice;
    # keep intact all notices stating that this License and any
    # non-permissive terms added in accord with section 7 apply to the code;
    # keep intact all notices of the absence of any warranty; and give all
    # recipients a copy of this License along with the Program.
    # You may charge any price or no price for each copy that you convey,
    # and you may offer support or warranty protection for a fee.
    # 5. Conveying Modified Source Versions.
    # You may convey a work based on the Program, or the modifications to
    # produce it from the Program, in the form of source code under the
    # terms of section 4, provided that you also meet all of these conditions:
    # a) The work must carry prominent notices stating that you modified
    # it, and giving a relevant date.
    # b) The work must carry prominent notices stating that it is
    # released under this License and any conditions added under section
    # 7. This requirement modifies the requirement in section 4 to
    # "keep intact all notices".
    # c) You must license the entire work, as a whole, under this
    # License to anyone who comes into possession of a copy. This
    # License will therefore apply, along with any applicable section 7
    # additional terms, to the whole of the work, and all its parts,
    # regardless of how they are packaged. This License gives no
    # permission to license the work in any other way, but it does not
    # invalidate such permission if you have separately received it.
    # d) If the work has interactive user interfaces, each must display
    # Appropriate Legal Notices; however, if the Program has interactive
    # interfaces that do not display Appropriate Legal Notices, your
    # work need not make them do so.
    # A compilation of a covered work with other separate and independent
    # works, which are not by their nature extensions of the covered work,
    # and which are not combined with it such as to form a larger program,
    # in or on a volume of a storage or distribution medium, is called an
    # "aggregate" if the compilation and its resulting copyright are not
    # used to limit the access or legal rights of the compilation's users
    # beyond what the individual works permit. Inclusion of a covered work
    # in an aggregate does not cause this License to apply to the other
    # parts of the aggregate.
    # 6. Conveying Non-Source Forms.
    # You may convey a covered work in object code form under the terms
    # of sections 4 and 5, provided that you also convey the
    # machine-readable Corresponding Source under the terms of this License,
    # in one of these ways:
    # a) Convey the object code in, or embodied in, a physical product
    # (including a physical distribution medium), accompanied by the
    # Corresponding Source fixed on a durable physical medium
    # customarily used for software interchange.
    # b) Convey the object code in, or embodied in, a physical product
    # (including a physical distribution medium), accompanied by a
    # written offer, valid for at least three years and valid for as
    # long as you offer spare parts or customer support for that product
    # model, to give anyone who possesses the object code either (1) a
    # copy of the Corresponding Source for all the software in the
    # product that is covered by this License, on a durable physical
    # medium customarily used for software interchange, for a price no
    # more than your reasonable cost of physically performing this
    # conveying of source, or (2) access to copy the
    # Corresponding Source from a network server at no charge.
    # c) Convey individual copies of the object code with a copy of the
    # written offer to provide the Corresponding Source. This
    # alternative is allowed only occasionally and noncommercially, and
    # only if you received the object code with such an offer, in accord
    # with subsection 6b.
    # d) Convey the object code by offering access from a designated
    # place (gratis or for a charge), and offer equivalent access to the
    # Corresponding Source in the same way through the same place at no
    # further charge. You need not require recipients to copy the
    # Corresponding Source along with the object code. If the place to
    # copy the object code is a network server, the Corresponding Source
    # may be on a different server (operated by you or a third party)
    # that supports equivalent copying facilities, provided you maintain
    # clear directions next to the object code saying where to find the
    # Corresponding Source. Regardless of what server hosts the
    # Corresponding Source, you remain obligated to ensure that it is
    # available for as long as needed to satisfy these requirements.
    # e) Convey the object code using peer-to-peer transmission, provided
    # you inform other peers where the object code and Corresponding
    # Source of the work are being offered to the general public at no
    # charge under subsection 6d.
    # A separable portion of the object code, whose source code is excluded
    # from the Corresponding Source as a System Library, need not be
    # included in conveying the object code work.
    # A "User Product" is either (1) a "consumer product", which means any
    # tangible personal property which is normally used for personal, family,
    # or household purposes, or (2) anything designed or sold for incorporation
    # into a dwelling. In determining whether a product is a consumer product,
    # doubtful cases shall be resolved in favor of coverage. For a particular
    # product received by a particular user, "normally used" refers to a
    # typical or common use of that class of product, regardless of the status
    # of the particular user or of the way in which the particular user
    # actually uses, or expects or is expected to use, the product. A product
    # is a consumer product regardless of whether the product has substantial
    # commercial, industrial or non-consumer uses, unless such uses represent
    # the only significant mode of use of the product.
    # "Installation Information" for a User Product means any methods,
    # procedures, authorization keys, or other information required to install
    # and execute modified versions of a covered work in that User Product from
    # a modified version of its Corresponding Source. The information must
    # suffice to ensure that the continued functioning of the modified object
    # code is in no case prevented or interfered with solely because
    # modification has been made.
    # If you convey an object code work under this section in, or with, or
    # specifically for use in, a User Product, and the conveying occurs as
    # part of a transaction in which the right of possession and use of the
    # User Product is transferred to the recipient in perpetuity or for a
    # fixed term (regardless of how the transaction is characterized), the
    # Corresponding Source conveyed under this section must be accompanied
    # by the Installation Information. But this requirement does not apply
    # if neither you nor any third party retains the ability to install
    # modified object code on the User Product (for example, the work has
    # been installed in ROM).
    # The requirement to provide Installation Information does not include a
    # requirement to continue to provide support service, warranty, or updates
    # for a work that has been modified or installed by the recipient, or for
    # the User Product in which it has been modified or installed. Access to a
    # network may be denied when the modification itself materially and
    # adversely affects the operation of the network or violates the rules and
    # protocols for communication across the network.
    # Corresponding Source conveyed, and Installation Information provided,
    # in accord with this section must be in a format that is publicly
    # documented (and with an implementation available to the public in
    # source code form), and must require no special password or key for
    # unpacking, reading or copying.
    # 7. Additional Terms.
    # "Additional permissions" are terms that supplement the terms of this
    # License by making exceptions from one or more of its conditions.
    # Additional permissions that are applicable to the entire Program shall
    # be treated as though they were included in this License, to the extent
    # that they are valid under applicable law. If additional permissions
    # apply only to part of the Program, that part may be used separately
    # under those permissions, but the entire Program remains governed by
    # this License without regard to the additional permissions.
    # When you convey a copy of a covered work, you may at your option
    # remove any additional permissions from that copy, or from any part of
    # it. (Additional permissions may be written to require their own
    # removal in certain cases when you modify the work.) You may place
    # additional permissions on material, added by you to a covered work,
    # for which you have or can give appropriate copyright permission.
    # Notwithstanding any other provision of this License, for material you
    # add to a covered work, you may (if authorized by the copyright holders of
    # that material) supplement the terms of this License with terms:
    # a) Disclaiming warranty or limiting liability differently from the
    # terms of sections 15 and 16 of this License; or
    # b) Requiring preservation of specified reasonable legal notices or
    # author attributions in that material or in the Appropriate Legal
    # Notices displayed by works containing it; or
    # c) Prohibiting misrepresentation of the origin of that material, or
    # requiring that modified versions of such material be marked in
    # reasonable ways as different from the original version; or
    # d) Limiting the use for publicity purposes of names of licensors or
    # authors of the material; or
    # e) Declining to grant rights under trademark law for use of some
    # trade names, trademarks, or service marks; or
    # f) Requiring indemnification of licensors and authors of that
    # material by anyone who conveys the material (or modified versions of
    # it) with contractual assumptions of liability to the recipient, for
    # any liability that these contractual assumptions directly impose on
    # those licensors and authors.
    # All other non-permissive additional terms are considered "further
    # restrictions" within the meaning of section 10. If the Program as you
    # received it, or any part of it, contains a notice stating that it is
    # governed by this License along with a term that is a further
    # restriction, you may remove that term. If a license document contains
    # a further restriction but permits relicensing or conveying under this
    # License, you may add to a covered work material governed by the terms
    # of that license document, provided that the further restriction does
    # not survive such relicensing or conveying.
    # If you add terms to a covered work in accord with this section, you
    # must place, in the relevant source files, a statement of the
    # additional terms that apply to those files, or a notice indicating
    # where to find the applicable terms.
    # Additional terms, permissive or non-permissive, may be stated in the
    # form of a separately written license, or stated as exceptions;
    # the above requirements apply either way.
    # 8. Termination.
    # You may not propagate or modify a covered work except as expressly
    # provided under this License. Any attempt otherwise to propagate or
    # modify it is void, and will automatically terminate your rights under
    # this License (including any patent licenses granted under the third
    # paragraph of section 11).
    # However, if you cease all violation of this License, then your
    # license from a particular copyright holder is reinstated (a)
    # provisionally, unless and until the copyright holder explicitly and
    # finally terminates your license, and (b) permanently, if the copyright
    # holder fails to notify you of the violation by some reasonable means
    # prior to 60 days after the cessation.
    # Moreover, your license from a particular copyright holder is
    # reinstated permanently if the copyright holder notifies you of the
    # violation by some reasonable means, this is the first time you have
    # received notice of violation of this License (for any work) from that
    # copyright holder, and you cure the violation prior to 30 days after
    # your receipt of the notice.
    # Termination of your rights under this section does not terminate the
    # licenses of parties who have received copies or rights from you under
    # this License. If your rights have been terminated and not permanently
    # reinstated, you do not qualify to receive new licenses for the same
    # material under section 10.
    # 9. Acceptance Not Required for Having Copies.
    # You are not required to accept this License in order to receive or
    # run a copy of the Program. Ancillary propagation of a covered work
    # occurring solely as a consequence of using peer-to-peer transmission
    # to receive a copy likewise does not require acceptance. However,
    # nothing other than this License grants you permission to propagate or
    # modify any covered work. These actions infringe copyright if you do
    # not accept this License. Therefore, by modifying or propagating a
    # covered work, you indicate your acceptance of this License to do so.
    # 10. Automatic Licensing of Downstream Recipients.
    # Each time you convey a covered work, the recipient automatically
    # receives a license from the original licensors, to run, modify and
    # propagate that work, subject to this License. You are not responsible
    # for enforcing compliance by third parties with this License.
    # An "entity transaction" is a transaction transferring control of an
    # organization, or substantially all assets of one, or subdividing an
    # organization, or merging organizations. If propagation of a covered
    # work results from an entity transaction, each party to that
    # transaction who receives a copy of the work also receives whatever
    # licenses to the work the party's predecessor in interest had or could
    # give under the previous paragraph, plus a right to possession of the
    # Corresponding Source of the work from the predecessor in interest, if
    # the predecessor has it or can get it with reasonable efforts.
    # You may not impose any further restrictions on the exercise of the
    # rights granted or affirmed under this License. For example, you may
    # not impose a license fee, royalty, or other charge for exercise of
    # rights granted under this License, and you may not initiate litigation
    # (including a cross-claim or counterclaim in a lawsuit) alleging that
    # any patent claim is infringed by making, using, selling, offering for
    # sale, or importing the Program or any portion of it.
    # 11. Patents.
    # A "contributor" is a copyright holder who authorizes use under this
    # License of the Program or a work on which the Program is based. The
    # work thus licensed is called the contributor's "contributor version".
    # A contributor's "essential patent claims" are all patent claims
    # owned or controlled by the contributor, whether already acquired or
    # hereafter acquired, that would be infringed by some manner, permitted
    # by this License, of making, using, or selling its contributor version,
    # but do not include claims that would be infringed only as a
    # consequence of further modification of the contributor version. For
    # purposes of this definition, "control" includes the right to grant
    # patent sublicenses in a manner consistent with the requirements of
    # this License.
    # Each contributor grants you a non-exclusive, worldwide, royalty-free
    # patent license under the contributor's essential patent claims, to
    # make, use, sell, offer for sale, import and otherwise run, modify and
    # propagate the contents of its contributor version.
    # In the following three paragraphs, a "patent license" is any express
    # agreement or commitment, however denominated, not to enforce a patent
    # (such as an express permission to practice a patent or covenant not to
    # sue for patent infringement). To "grant" such a patent license to a
    # party means to make such an agreement or commitment not to enforce a
    # patent against the party.
    # If you convey a covered work, knowingly relying on a patent license,
    # and the Corresponding Source of the work is not available for anyone
    # to copy, free of charge and under the terms of this License, through a
    # publicly available network server or other readily accessible means,
    # then you must either (1) cause the Corresponding Source to be so
    # available, or (2) arrange to deprive yourself of the benefit of the
    # patent license for this particular work, or (3) arrange, in a manner
    # consistent with the requirements of this License, to extend the patent
    # license to downstream recipients. "Knowingly relying" means you have
    # actual knowledge that, but for the patent license, your conveying the
    # covered work in a country, or your recipient's use of the covered work
    # in a country, would infringe one or more identifiable patents in that
    # country that you have reason to believe are valid.
    # If, pursuant to or in connection with a single transaction or
    # arrangement, you convey, or propagate by procuring conveyance of, a
    # covered work, and grant a patent license to some of the parties
    # receiving the covered work authorizing them to use, propagate, modify
    # or convey a specific copy of the covered work, then the patent license
    # you grant is automatically extended to all recipients of the covered
    # work and works based on it.
    # A patent license is "discriminatory" if it does not include within
    # the scope of its coverage, prohibits the exercise of, or is
    # conditioned on the non-exercise of one or more of the rights that are
    # specifically granted under this License. You may not convey a covered
    # work if you are a party to an arrangement with a third party that is
    # in the business of distributing software, under which you make payment
    # to the third party based on the extent of your activity of conveying
    # the work, and under which the third party grants, to any of the
    # parties who would receive the covered work from you, a discriminatory
    # patent license (a) in connection with copies of the covered work
    # conveyed by you (or copies made from those copies), or (b) primarily
    # for and in connection with specific products or compilations that
    # contain the covered work, unless you entered into that arrangement,
    # or that patent license was granted, prior to 28 March 2007.
    # Nothing in this License shall be construed as excluding or limiting
    # any implied license or other defenses to infringement that may
    # otherwise be available to you under applicable patent law.
    # 12. No Surrender of Others' Freedom.
    # If conditions are imposed on you (whether by court order, agreement or
    # otherwise) that contradict the conditions of this License, they do not
    # excuse you from the conditions of this License. If you cannot convey a
    # covered work so as to satisfy simultaneously your obligations under this
    # License and any other pertinent obligations, then as a consequence you may
    # not convey it at all. For example, if you agree to terms that obligate you
    # to collect a royalty for further conveying from those to whom you convey
    # the Program, the only way you could satisfy both those terms and this
    # License would be to refrain entirely from conveying the Program.
    # 13. Use with the GNU Affero General Public License.
    # Notwithstanding any other provision of this License, you have
    # permission to link or combine any covered work with a work licensed
    # under version 3 of the GNU Affero General Public License into a single
    # combined work, and to convey the resulting work. The terms of this
    # License will continue to apply to the part which is the covered work,
    # but the special requirements of the GNU Affero General Public License,
    # section 13, concerning interaction through a network will apply to the
    # combination as such.
    # 14. Revised Versions of this License.
    # The Free Software Foundation may publish revised and/or new versions of
    # the GNU General Public License from time to time. Such new versions will
    # be similar in spirit to the present version, but may differ in detail to
    # address new problems or concerns.
    # Each version is given a distinguishing version number. If the
    # Program specifies that a certain numbered version of the GNU General
    # Public License "or any later version" applies to it, you have the
    # option of following the terms and conditions either of that numbered
    # version or of any later version published by the Free Software
    # Foundation. If the Program does not specify a version number of the
    # GNU General Public License, you may choose any version ever published
    # by the Free Software Foundation.
    # If the Program specifies that a proxy can decide which future
    # versions of the GNU General Public License can be used, that proxy's
    # public statement of acceptance of a version permanently authorizes you
    # to choose that version for the Program.
    # Later license versions may give you additional or different
    # permissions. However, no additional obligations are imposed on any
    # author or copyright holder as a result of your choosing to follow a
    # later version.
    # 15. Disclaimer of Warranty.
    # THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
    # APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
    # HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
    # OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
    # THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    # PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
    # IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
    # ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    # 16. Limitation of Liability.
    # IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    # WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
    # THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
    # GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
    # USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
    # DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
    # PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
    # EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
    # SUCH DAMAGES.
    # 17. Interpretation of Sections 15 and 16.
    # If the disclaimer of warranty and limitation of liability provided
    # above cannot be given local legal effect according to their terms,
    # reviewing courts shall apply local law that most closely approximates
    # an absolute waiver of all civil liability in connection with the
    # Program, unless a warranty or assumption of liability accompanies a
    # copy of the Program in return for a fee.
    # END OF TERMS AND CONDITIONS
    # How to Apply These Terms to Your New Programs
    # If you develop a new program, and you want it to be of the greatest
    # possible use to the public, the best way to achieve this is to make it
    # free software which everyone can redistribute and change under these terms.
    # To do so, attach the following notices to the program. It is safest
    # to attach them to the start of each source file to most effectively
    # state the exclusion of warranty; and each file should have at least
    # the "copyright" line and a pointer to where the full notice is found.
    # <one line to give the program's name and a brief idea of what it does.>
    # Copyright (C) <year> <name of author>

    # along with this program. If not, see <http://www.gnu.org/licenses/>.

    # If the program does terminal interaction, make it output a short
    # notice like this when it starts in an interactive mode:
    # <program> Copyright (C) <year> <name of author>
    # This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    # This is free software, and you are welcome to redistribute it
    # under certain conditions; type `show c' for details.
    # The hypothetical commands `show w' and `show c' should show the appropriate
    # parts of the General Public License. Of course, your program's commands
    # might be different; for a GUI interface, you would use an "about box".
    # You should also get your employer (if you work as a programmer) or school,
    # if any, to sign a "copyright disclaimer" for the program, if necessary.

  • How do I send a .pdf file in the body of email, not as attachment?

    Hello to all you MAC geniuses out there. I am using Pages to design flyers for my business. Then exporting them to a pdf file and trying to figure out how to send them in the BODY of an email and not an attachemnt that they have to open. Not really sure if this is a mail or pages question. It is probably a very simple step I am missing, but never the less can't seem to fiugre it out. Thanks in advance!
    Genn

    You must take into consideration that HTML & PDF are very different formats with conflicting purposes: HTML is by design intended for flexibility in appearance in such things as font & location of displayed elements, & has no fixed page size. PDF is intended to produce WYSIWYG documents, exactly the same regardless of platform, but requires either the Adobe Acrobat application or a PDF plug-in to do so.
    Because of this, there is no way to convert a PDF document into HTML that will completely preserve the PDF's appearance. You can more or less force elements into the same relative position using tables & other HTML features, but pagination cannot be preserved, since no HTML formatted documents will have page breaks.
    You also should consider that the appearance of an email message depends on the application used to view it. Most email, including what Mail generates, follows a standard known as MIME 1.0. MIME is designed to identify each element in the message such that different applications can process them according to their capabilities. Thus, since Mail knows how to display image files like gifs, tiffs, or jpegs, they will be displayed as if they were embedded in the text if the MIME tags indicate they should be. Anything Mail doesn't know how to process into displayable text or images, such as PDF's, will be displayed only as an attachment. The same will be true for other email reading applications.
    IOW, email is not WYSIWYG. Some apps will show displayable items inline, some won't, even if the MIME type is displayable on your Mac in Mail.
    There are several ways you can deal with this. You can try to convert the PDF into HTML, as suggested earlier. You will probably have to tweak the HTML so generated with an editor to get the best results, & deal with such things as pagination, image conversion or resizing, so-called web safe colors, etc. (PDF's are compressed & usually optimized for high resolution printing; to keep the message size down, you may want to convert images to lower resolution jpegs.)
    Or, you can convert the entire flyer to a jpeg or png image, which insures WYSIWYG output, but may make text harder to read.
    Alternately, you can compose a new message as plain text or as HTML that refers to the PDF's content & either includes it as an attachment or furnishes a link to a web page that contains it. This allows you to reach the widest audience, including those who do not have a PDF app or plug-in.
    Whatever you elect to do, remember that what you send in the email is actually a combination of content & instructions about how to deal with it, & that not all recipients will see it the same way, no matter what you do.

  • Dump data from a table into wwv_flow_files

    HI,
    Could you help me, to take data from a table, and insert it into blob_content in wwv_flow_files; and data should be stored in a .txt file

    This is not really an APEX metadata table, Alex. As far as I recall, it is a standard mod_plsql documents table that handles file uploads. One can also insert a document into the table dkirectly using an INSERT as it pretty straight forward.
    Not exactly sure why though as the doc download procedure needs a LOB or CLOB.. and it does not care from what table you create it from - or whether you do it on the fly.
    But still, you make an important point of using application/system objects for the purpose they have been designed for. And in this case, creating your own documents table may be a lot better.

  • What is the best way to interface to an iDevice via Bluetooth?

    I am going to be designing a piece of hardware which will interact with an iDevice, (iphone / ipad), via Bluetooth.  I will be enrolling in the MFi program.  It is my intent to stream data from my hardware to an iDevice through a Bluetooth module essentially making a wireless wire i.e., serial data pipe connection.
    My questions are:
    What transfer speeds can I expect to achieve with iDevices?
    Which Bluetooth Versions, 2.0 or 4.0, are recommended for this type of application?
    Do I need an authentication coprocessor and if so how much do they cost?
    Are there any preferred modules to use for this purpose; I’m currently designing around the RN-42 module?  

    Run a cable through the hole in the stand and lock it to the desk. There are lots of security products out there to do this, here is a good sample to look for:

    Ther is compatibility problem that happend with broken binaries
    errno shouldn't show up with binary or library compiled against glibc 2.1+
    You can use LD_ASSUME_KERNEL=2.4.1 (or 2.2.5) in the broken apps env
    to work around this.

    LINUX: Quick Start Guide - 9.2.0 RDBMS Installation
    Quick Start Guide Oracle9i Release 2 (9.2.0) RDBMS Installation Linux Operating System PURPOSE ======= This document is designed to be a quick reference that can be used when installing Oracle 9.2.0 on the Linux platform. It is NOT designed to take the place of the Installation Guide. It is recommended that users READ the installation guide. Instructions to locate that document are contained in Appendix A. A familiarity with the Linux Operating System is assumed. If Installation guide information is needed, please see the Appendix A at the bottom of this document for additional resources. Each step should be done in the order that it is listed. These steps are the bare minimum that is necessary for a typical install of the Oracle9i RDBMS. Verification of Version Certification: ====================================== Currently, Oracle 9.2.0 is certified ONLY on the following Intel Based Server Linux distributions: - Red Hat Advanced Server 2.1 - Suse SLES7, SLES8 - United Linux 1.0 For the latest certification and other related information, use the "Certify & Availability" link in Metalink. Installations on distributions and versions not listed in the Certify link is not supported. Pre-requisite Requirements for System Administrator: ==================================================== The following steps are required to verify your operating system meets minimum requirements for installation, and should be performed by the root user. For assistance with system administration issues, please contact your system administrator or operating system vendor. Use these steps to manually check the operating system requirements before attempting to install Oracle RDBMS software, or you may choose to use the convenient "Unix InstallPrep script" which automates these checks for you. For more information about the script, including download information, please review the following article: Note:189256.1 UNIX: Script to Verify Installation Requirements for Oracle 9.x version of RDBMS Users must have /bin/utils installed for the operating system. This is part of the developers option on RedHat Advanced Server 2.1. The Following Steps Need to be Performed by the Root User: 1. Configure System Resources: Ensure that the system has at least the following resources: ? 400 MB in /tmp * ? 512 MB of Physical Memory (RAM) ? Three times the amount of Physical Memory for Swap space (unless the system exceeds 1 GB of Physical Memory, where two times the amount of Physical Memory for Swap space is sufficient) * You may also redirect /tmp by setting the TEMP environment variable. This is only recommended in rare circumstances where /tmp cannot be expanded to meet free space requirements. 2. Create a Software Owner and Group: Create a Unix user and group that will own the Oracle software. (Typically user = oracle, group = dba) You may use a GUI tool for this if your distirbution provides one, or the 'useradd' and 'groupadd' command line utilities. Please make sure the user and group you use are defined in the local /etc/passwd and /etc/group files rather than resolved via a network service such as NIS. 3. Create a Software Mount Point and DataFile Mount Points: Create a mount point for the Oracle software installation (at least 2.5 GB, typically /u01) Create a second, third and fourth mount point for the database files, control files, and log files to be created (typically /u02, /u03, /u04). ? The oracle user should own these mount points and all of the directories below the mount point. 4. Test the Permissions: Ensure that the oracle user can write to the new mount points ? As a test, change directories to each of the new mount point directories as the oracle user and create a file or directory. Example: % touch /u01/test 5. Configure Kernel Resources: The following kernel parameters related to shared memory and semaphores will require tuning:      SHMMAX = 2147483648      SHMMIN = 1      SHMMNI = 100      SEMMNS = 1000      SEMMSL = 250      SEMMNI = 100      SEMOPM = 100 6.On Linux kernel parameters can be set dynamically or can be written in a shell script to be set at boot time. Kernel parameters should be set as the root user. They are set as follows 1.     cd /proc/sys/kernel 2.     Modify the parameter values by using the following command syntax: a.     # echo 100 32000 100 100 > sem           This sets SEMMSL, SEMMNS, SEMOPM, SEMMNI b.     # echo 2147483648 > shmmax c.     # echo 1 > shmmin d.     # echo 100 > shmmni ================================================================================ These changes are NOT persistent and must be re-set after each re-boot. On RedHat Advanced Server 2.1, these parameters can be entered into the file /etc/sysctl.conf. This parameters in this file are set each time the system is booted. Example:      $ more /etc/sysctl.conf      # Disables packet forwarding      net.ipv4.ip_forward = 0      # Enables source route verification      net.ipv4.conf.default.rp_filter = 1      # Disables the magic-sysrq key      kernel.sysrq = 0      kernel.shmmax=256000000      kernel.shmmin=1      kernel.shmmni=100      kernel.sem= 250 32000 32 128 7. Mount CD-ROM: Depending on your Linux distribution the cdrom device is typically either "/cdrom" or "/mnt/cdrom". Please substitute the appropriate value when "<cdrom>" appears in the examples. # mount <cdrom> Installs can be done from either the CD or by copying the contents of each CD?s to a stage area on the local disk (/stage/Disk1, /stage/Disk2, /stage/DiskN) 8.This is required to run as root: /tmp/orainstRoot.sh First question of oracle installation. If no other versions of Oracle 8i or 9i have been installed before. You will be ask to run /tmp/orainstRoot.sh to create the oraInventory location pointer. Usually found in /etc on Linux Files that are located in /etc are /etc/oratab and /etc/oraInst.loc Installation Steps for the Oracle User ======================================= The Following Steps need to be performed by the Oracle User: This can be done from either a Telnet or an SSH connection. It is NOT recommended to perform installations from a su ? oracle connection. 1. Set Environment Variables Environment variables should be set in the login script for the oracle user. If the oracle user's default shell is the C-shell (/usr/bin/csh), then the login script will be named ".login". If the oracle user's default shell is the Bourne-shell (/usr/bin/bsh) or the Korn-shell (/usr/bin/sh or /usr/bin/ksh), then the login script will be named ".profile". In either case, the login script will be located in the oracle user's home directory ($HOME). The examples below assume that your software mount point is /u01. Parameter Value ----------- ------ ORACLE_HOME /u01/app/oracle/product/9.2.0 ORACLE_BASE /u01/app/oracle PATH /u01/app/oracle/product/9.2.0/bin: /usr/ccs/bin:/usr/bin/X11/:/usr/local/bin and any other items you require in                     your PATH      ORA_NLS33          $ORACLE_HOME/ocommon/nls/admin/data ORACLE_SID Set this to what you will call your database instance. (4 - 8 characters in length)      If you are not on the console, you may need to set the following DISPLAY <ip-address>:0.0 (review Note:153960.1 for detailed information) ENSURE THAT CLASS_PATH IS NOT SET IN THE ENVIRONMENT 2. Set the umask: Set the oracle user's umask to "022" in you ".profile" or ".login" file. Example: umask 022 3. Verify the Environment Log off and log on as the oracle user to ensure all environment variables are set correctly. Use the following command to view them: % env | more Before attempting to run the Oracle Universal Installer, verify that you can successfully run the following command: % /usr/bin/X11/xclock If this does not display a clock on your display screen, please review the following article: Note:153960.1 FAQ: X Server testing and troubleshooting 4. Start the Oracle Universal Installer and install the RDBMS software: Use the following commands to start the installer: % cd /tmp % /cdrom/runInstaller Or cd to /stage/Disk1 and run ./runInstaller Respond to the installer prompts as shown below: ? When prompted for whether orainstRoot.sh has been run by root, enter "y". This should have been done in Pre-Installation step 8 above. ? At the "Welcome Screen", click Next. ? If prompted, enter the directory to use for the "Inventory Location". This can be any directory, but is usually not under ORACLE_HOME because the oraInventory is shared with all Oracle products on the system. ? If prompted, enter the "UNIX Group Name" for the oracle user (dba). ? At the "File Locations Screen", verify the Destination listed is your ORACLE_HOME directory. Also enter a NAME to identify this ORACLE_HOME. The NAME can be anything, but is typically "DataServer" and the first three digits of the version. For example: "DataServer920" ? At the "Available Products Screen", choose Oracle9i Database, then click Next. ? At the "Installation Types Screen", choose Enterprise Edition, then click Next. ? If prompted, click Next at the "Component Locations Screen" to accept the default directories. ? At the "Database Configuration Screen", choose the the configuration based on how you plan to use the database, then click Next. ? If prompted, click Next at the "Privileged Operating System Groups Screen" to accept the default values (your current OS primary group). ? If prompted, enter the Global Database Name in the format "ORACLE_SID.hostname" at the "Database Identification Screen". For example: "TEST.LNXhost". The SID entry should be filled in with the value of ORACLE_SID. Click Next. ? If prompted, enter the directory where you would like to put datafiles at the "Database File Location Screen". Click Next. ? If prompted, select "Use the default character set" (WE8ISO8859P1) at the "Database Character Set Screen". Click Next. ? At the "Summary Screen", review your choices, then click Install. The install will begin. Follow instructions regarding running "root.sh" and any other prompts. When completed, the install will have created a default database, configured a Listener, and started both for you. Note: If you are having problems changing CD-ROMs when prompted to do so, please review the following article: Note:146566.1 How to Unmount / Eject First Cdrom Your Oracle9i Release 2 (9.2.0) RDBMS installation is now complete and ready for use.

    Also, I had the same problem happen when I tried to install an older version of Corel Painter. Are Macbook Pro users just NOT supposed to be able to use their laptops for the purposes they are best designed for?
