Is it possible to use multiple encryption algorithms in Oracle 10g RAC?
We have two separate databases on same physical servers, running 10g RAC Using TDE, is it possible to have different encryption algorithms for each database?
It is possible to have every column in a single table use a different algorithm.

It is possible to use multiple iPads in my own enterprise and to create an app just for my restaurant not in appstore???
Yes that's completely feasable.
Actually there is another way to install apps ad-hock that i was not aware of (this does not require the devices to be attatched to the Mac with the SDK and project, it can use any computer or distribute via your LAN:
iOS Developer Programme:Ad Hoc Distribution
With Ad Hoc distribution you can share your application with up to 100 other iPad, iPhone, or iPod touch users. Through email or by posting it to a website or server, users can download and install your app. -

Oracle 10g RAC using ASM - Storage Issue
I’ve an issue related to Oracle 10g RAC.
I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
I’ve EMC CX300 SAN storage with following partitions
/orasoft 10 Gb OCFS2 File system
/oracrs 2 Gb OCFS2 File system
/orabackup 100 Gb OCFS2 File system
The datafiles are on ASM which is not directly visible in OS.
I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
I’ve faced an issue recently related to EMC storage.
The /orasoft partition displays 1.4 Gb space available using df command.
With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
Is this setup correct ??
Can anyone help me with this storage issue ??Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
Here is what you can do:
- Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
- Create a ASM disk group which would mirror Disk_1 to Disk_2.
Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.

Are multiple PHYSICAL databases supported in one Oracle 10g RAC environment
Hi alls,
as of Metalink 220970.1 Oracle RAC is also supporting different databases in one cluster installation. RAC handles any resource as a service and it doesn't matter if these services belongs to only one or to different databases. You install the Oracle Clusterware only once and you create any service you want to make high available.
So is technically possible to install multiple databases on same Oracle Rac environment.
My doubts are related to SAP , does SAP certify such environments ?? we could have one SAP R/3 database and SAP BW database co-exist in a single Oracle RAC environment. or also co-exist SAP database with a non-SAP database (an already existing application) in the same Oracle Rac environment.
Any comment would be higly appreciated.
Silvio BrandaniWe have ECC, BI, PI and Portal running on same Oracle RAC environment. We have one RAC for QA systems and one for PRD systems. We are not running any SAP applications along with Non-SAP applications on RAC. Keeping SAP and non-SAP apps separate would be a way to go.
Hope this helps.
Thanks,

Using Clob with TopLink 9.0.4.5 and Oracle 10g RAC
I am trying to store an XML file in a Clob type field of a DB table using TopLink 9.0.4.5 and Oracle 10g RAC and need some guidance about how to do it. I got some directions to start it with the Tip "How-To: Map Large Objects (LOBs) to Oracle Databases with OracleAS TopLink" but still need some more helps.
When using the Oracle JDBC OCI driver, the tip gives the code block for a Clob field:
DirectToField scriptMapping = new DirectToField();
scriptMapping.setAttributeName("script");
scriptMapping.setFieldName("IMAGE.SCRIPT");
descriptor.addMapping(scriptMapping);
As I understand, TopLink creates instances of the Descriptor class at run time for each of the descriptor files and stores them in a database session, where is the proper place (in SessionEvent of TopLinkSessionEventHandler?) for me to get a reference to such an instance of my Descriptor class in Java code so that I can add the above mentioned additional Mapping? Are the above String values of "script" and "IMAGE.SCRIPT" predefined in TopLink API? Can I accomplish the same thing just using the TopLink Workbench tool instead? If yes, please advise the detailed steps to do so.
The tip also states to call the following code in case of using Clob:
DatabaseLogin login = session.getLogin();
login.useStringBinding();
Should the above 2 lines of code be called after the following lines of code?
SessionManager sessionManager = SessionManager.getManager();
Server serverSession = (Server)sessionManager.getSession("MY_SESSION_NAME");
Besides the above extra coding for the Session and Descriptor Mapping, is there any special handling in between Data model and DB table mapping? Can I map a Java String type to a DB Clob field using the Direct-to-field mapping?
Appreciate any help.Never mind ....... I had already figured it out .....

Help building an e-commerce site using DreamWeaver MX 2004 and Oracle 10G
I'm new to using Oracle 10G. After reviewing several rdms's I've picked Oracle 10G as my rdms. I'm trying to build an ecommerce site using DreamWeaver MX 2004 and Oracle 10G. The website will be selling hardware and software products. I have a choice in DreamWeaver to go for a .asp or .jsp setup. I have several questions, here goes:
1. Is there any book/tutorial/whitepaper out there that describes building an ecommerce site using Oracle 10G/9I/8I? Just some examples as how to make the datamodel regarding the shopping basket etc.
2. I prefer DreamWeaver as it let's me make nice looking css style based pages without throttling too much through the code. Are there Oracle tools which allow me to make an advanced nice looking ecommerce site?
I hope some of you can help me get started. Any effort is appreciated.

Using scatter graph type in oracle 10g forms using bi beans
hi.. how i can use scatter graph type in oracle 10g using bi beans..
it seems scatter graph is supported in 10g but it doesnt work at all..
i used to use oracle graphics builder in oracle 6i forms,now i need to convert all my old graphs to 10g forms..the line,bar and pie it work very well but the scatter didnt work..
so please if anyone know how to use it please tell me.. and what versions of bi beans support the scatter graph type
thanks.
u can email me in
[email protected]Hi,
What version of Oracle Forms are you using? If it is 10.1.2.0.2 (10g R2 Phase 2) then the BI Beans version should be 10.1.2.1 (3.2.2.0.24.2).
When you run a Graph, do you see any version numbers?
Regardless of the version, scatter graph should work. What kind of errors are you getting?
When you install BI Beans in JDeveloper, you get access to BI Beans Help. Go to the following topic for setting up data for a scatter graph:
Help -> Building Applications with BI Beans -> Presenting Data in Graphs -> Specifying Data for Graphs
Did you try posting your question on the Oracle Forms forum?

What is the use of SYSAUX Tablespace in Oracle 10G
Dear Experts,
Please Tell me What is the use of SYSAUX Tablespace in Oracle 10G Because
during Web Load Testing It is going to increase countinuosly.Although i am not using this with any tables.
How Can I find out the what is gong on in this.
Can I Remove this tablesspace and other non using Schemas like FLOWS_020100,MDSYS,OUTLN,DIP and TSMSYS etc.What is SYSAUX?
The SYSAUX tablespace provides storage of non-sys-related tables and indexes that traditionally were placed in the SYSTEM tablespace. For example, the tables and indexes that were previously owned by the system user can now be specified for a SYSAUX tablespace. Unfortunately, Oracle still places the SCOTT schema and the other demonstration schemas in the SYSTEM tablespace. Go figure.
The SYSAUX tablespace is specified with the CREATE DATABASE command. This is demonstrated in the example database creation script in Figure 1.1.
CREATE DATABASE test
MAXINSTANCES 1
MAXLOGHISTORY 1
MAXLOGFILES 5
MAXLOGMEMBERS 3
MAXDATAFILES 100

GROUP 3 ('/usr/oracle/OraHome1/oradata/aultdb1/test/redo03.log') SIZE 10240K
USER SYS IDENTIFIED BY "password" USER SYSTEM IDENTIFIED BY "password";
Oracle10g sysaux
With the new SYSAUX tablespace, Oracle comes closer to providing all the needed tablespaces for a truly OFA-compliant database right out of the box. With just one CREATE DATABASE command we can specify the SYSTEM tablespace, the TEMPORARY tablespace, the AUXSYS tablespace, the default UNDO tablespace, and the redo logs.
Of course, with the Oracle Managed Files option you can create an entire database with a single command, but the database created is not suitable for production use and is not OFA-compliant.
The SYSAUX tablespace is required in all new 10g databases. Only the SYSAUX tablespace datafile location is specified. Oracle specifies the remainder of the tablespace properties including:
online
permanent
read write
extent managment local
segment space management auto
If a datafile is specified for the SYSTEM tablespace, then one must be specified for the SYSAUX tablespace as well. If one is not specified, then the CREATE DATABASE command will fail. The only exception is for an Oracle Managed File system.
During any update of a database to Oracle Database 10g, a SYSAUX tablespace must be created or the upgrade will fail. The SYSAUX tablespace has the same security profile as the SYSTEM tablespace. However, loss of the SYSAUX tablespace will not result in a database crash, only the functional loss of the schemas it contains.
Can I drop SysAux?

Memory Leak when TOMCAT connects to Oracle 10g RAC using JDBC Thin driver.
We had experienced Memory leak when a Oracle 10g (10.2.0.3) RAC node was evicted. TOMCAT app server is connecting to the Oracle 10g RAC database instances using JDBC 10.2.0.3 thin driver.
Anyone had similar experience?
Any ideas? Any bugs reported/fixed?
Thanks,
RajIf you're doing XA, we absolutely do not support
driver-level load-balancing OR failover. Use neither.
For non-XA, you can use driver-level failover. For
non-XA, you could set load-balancing, but it won't
help because we get connections from the driver,
and keep them indefinitely, so the driver never gets
the chance to affect which connections the pool
uses after that. -
Is it possible to use multiple heterogeneous database connection in InfoVie
Iu2019m trying to develop a report that creates a list from one database (Oracle) and retrieves additional data from a different database server (db2) using a subreport. Iu2019m using BusinessView to access the data and I have successfully tested the report in Crystal XI R2. When I publish the report in to InfoView BusinessObjects XI R2 the sub-reports donu2019t retrieve the data.
Can this be accomplished with what I have describe or do I have to move the data to a single data source?
Thank you in advance,

Is it possible to use multiple hard drives with iphoto?
I am pretty new to Mac's so bear with me, I used to use multiple hard drives on my pc with my photos seperated by catagory in different hard drives. Is it possible to run iphoto with multiple hard drives without the photos loading onto my Imac? If so, How do I set it up. I have tried importing to a external drive, but when I check the file path of the photos it shows my Imac hd in the address. I seriously dont know why I cant just add the external hard drive as a library and have Iphoto work, Help
There are instructions - and not the caveats - on how to do what you want below.
However, you'e not quite grasping iPhoto:
I used to use multiple hard drives on my pc with my photos seperated by catagory in different hard drives.
When you do this, you're using the Finder (or file manager) to categorise the photos. All well and good, but why? That's exactly iPhoto's job. iPhoto is a database designed to help you manage your pics - including categorising them.
Anyway:
*How to do it:*
Simply go to iPhoto Menu -> Preferences -> Advanced and uncheck 'Copy Files to the iPhoto Library on Import'.
*What Happens:*
Now iPhoto will not copy the files, but rather simply reference them on your HD. To do this it will create an alias in the Originals Folder that points to your file. It will still create a thumbnail and, if you modify the pics, a Modified version within the iPhoto Library Folder.
*Some things to consider:*
1. Importing and deleting pics are more complex procedures. You have to to put the files where they will be stored before importing them. When you delete them you'll need to remove the files from the HD yourself.
2. You cannot move or rename the files on your system or iPhoto will lose track of them on systems prior to 10.5 and iPhoto 08. Even with the later versions issues can still arise if you move the referenced files to new volumes or between volumes.
3. Most importantly, migrating to a new disk or computer can be much more complex.
4. *Because iPhoto has no tools for managing Referenced Files, if, for some reason, the path to the photos changes then you could find yourself resolving aliases for +each photo in the Library+ one by one.*
My own opinion:
I've yet to see a good reason to run iPhoto in referenced mode unless you're using two photo organisers
If disk space is an issue, you can run an entire iPhoto Library from an external disk:
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.
If you're concerned about accessing the files, There are many, many ways to access your files in iPhoto:
*For Users of 10.5 and later*
You can use any Open / Attach / Browse dialogue. On the left there's a Media heading, your pics can be accessed there. Command-Click for selecting multiple pics.
Uploaded with plasq's Skitch!
You can access the Library from the New Message Window in Mail:
Uploaded with plasq's Skitch!
*For users of 10.4 and later* ...
Many internet sites such as Flickr and SmugMug have plug-ins for accessing the iPhoto Library. If the site you want to use doesn’t then some, one or any of these will also work:
To upload to a site that does not have an iPhoto Export Plug-in the recommended way is to Select the Pic in the iPhoto Window and go File -> Export and export the pic to the desktop, then upload from there. After the upload you can trash the pic on the desktop. It's only a copy and your original is safe in iPhoto.
This is also true for emailing with Web-based services. However, if you're using Gmail you can use iPhoto2GMail
If you use Apple's Mail, Entourage, AOL or Eudora you can email from within iPhoto.
If you use a Cocoa-based Browser such as Safari, you can drag the pics from the iPhoto Window to the Attach window in the browser.
*If you want to access the files with iPhoto not running*:
For users of 10.6 and later:
You can download a free Services component from MacOSXAutomation which will give you access to the iPhoto Library from your Services Menu. Using the Services Preference Pane you can even create a keyboard shortcut for it.
For Users of 10.4 and later:
Create a Media Browser using Automator (takes about 10 seconds) or use this free utility Karelia iMedia Browser
Other options include:
1. *Drag and Drop*: Drag a photo from the iPhoto Window to the desktop, there iPhoto will make a full-sized copy of the pic.
2. *File -> Export*: Select the files in the iPhoto Window and go File -> Export. The dialogue will give you various options, including altering the format, naming the files and changing the size. Again, producing a copy.
3. *Show File*: Right- (or Control-) Click on a pic and in the resulting dialogue choose 'Show File'. A Finder window will pop open with the file already selected.
If you really want to spread your photos across volumes like this, Aperture would be a better fit.
