    We are planning to implement WEBMTHODS and METAMATRIX tool. These apps require Oracle database. We are planning 3 HP rp4410 servers running HP-UX 11i. One foe WEBMETHODS APP, ONE FOR METAMATRIX. BOTH APPS are using one ORACLE DB server.
    I am looking some type of ORACLE 10g server sizing information to support ny hardware configuration. Can someone help me where to find this information?
    Thanks.

    Hi
    What is AFAIK? As Far As I Know
    Can you send the contact info?Unless you're not living in the same country (please see my profile), I don't think it would make any sense. I do know that hp.at offers sizing information.
    If you are refering to Just HP support I did contact
    them. They asked me to contact Oracle. I am looking
    for some guideline documentation.So thing are a bit different in your country ...

  • Error when installing 9.0.1.4.0 patch set for the Oracle Database Server.

    Hi to all.
    Currently, i am trying to install patches for portal server.
    The server OS is Sun Solaris 8.
    We are using Oracle9iAS.
    Now, we are installing 9.0.1.4.0 patch set for the Oracle Database Server.
    We managed to install the patch, but have problem with the Post Install Action.
    We managed to run
    -ALTER SYSTEM ENABLE RESTRICTED SESSION;
    -@rdbms/admin/catpatch.sql
    -ALTER SYSTEM DISABLE RESTRICTED SESSION;
    -CONNECT / AS SYSDBA
    -update obj$ set status=5 where type#=29 and owner#!=0;
    -commit;
    But, when we come to the next command, which is to shutdown, it gives us like
    this..
    SQL> update obj$ set status=5 where type#=29 and owner#!=0;
    1402 rows updated.
    SQL> commit;
    Commit complete.
    SQL> shutdown immediate
    Database closed.
    Database dismounted.
    ORA-00604: error occurred at recursive SQL level 1
    ORA-01219: database not open: queries allowed on fixed tables/views only
    We tried to startup the database..it gives us this error..
    SQL> startup
    ORA-01081: cannot start already-running ORACLE - shut it down first
    So, we tried to shutdown again..
    SQL> shutdown immediate
    ORA-01089: immediate shutdown in progress - no operations are permitted
    I been informed that this is maybe a Database problem related. Any ideas?
    Best Wishes,
    Rushdan Md Saad.

    Patchsets could be obtained (only) from http://metalink.oracle.com
    You need to have valid CSI for access.
    P.S: Sorry Werner, I didn't see you post.

    Initially i tried to access pdf file from database server. I didn't get any solution for that. So I copied all my pdf files to Application server which is in Linux environment at "/home2/docs" directory.
    I gave the following command for accessing the pdf files kept in Lnux Application Server from Oracle 10g forms in a button press trigger.
    web.show_document('http://192.168.1.53:7779/home2/docs/test.pdf');
    It says "page cannot be found"
    So I copied one of the pdf file named "test.pdf" to "/oracle/oas10g/IasHome/forms90/java" in Linux Application Server . Then the following command
    web.show_document('http://192.168.1.53:7779/forms90/java/test.pdf');
    has opened the the pdf file in browser.
    192.168.1.53 is my Linux Application Server IP. and 7779 is the port.
    Actually we have lacs of pdf files. So i cannot keep all the pdf files in "/oracle/oas10g/IasHome/forms90/java" directory in Linux Application Server. And also all the pdf files not in the same directory , "/home2/docs" some of the pdf files r in the subdirectories of "/home2/docs/" like /home2/docs/sub1, /home2/docs/sub2, /home2/docs/sub3 etc.
    Then how to configure my "/oracle/oas10g/IasHome/forms90/server/forms90.conf" file for retrieving pdf files from "/home2/docs/" and its subdirectories. Is Anything other than this, required for solving my problems.
    Now My PDF files r in LINUX APPLICATION SERVER not in database server.

  • Where can I get Oracle database server 9i for windows 2003

    Hi,
    I need Oracle Database Server 9i for Windows 2003. From Oracle online download, there is one a patch set available. Where can I get the full version?
    Thanks
    Laura

    Hi, I found the solution. There is no software to direcly install Oracle 9i on Windows 2003. I need to install the software for NT/2000 first, the patch it.
    That's why there is only patchset for 2003 for downloading. See the doc below:
    three installation components required to install
    Oracle9i Database release 2 (9.2.0.3.0) on Windows Server 2003. These three
    installation components must be installed in the order listed. If you are
    migrating a pre-existing Oracle9i database to Windows Server 2003, first
    upgrade the database to the Oracle9i Database release 2 (9.2.0.3.0) patch set
    before upgrading the operating system.
    Obtain the following installation components:
    Oracle9i Database Release 2 (9.2.0.1.0) for Windows
    Oracle Universal Installer release 2.2.0.18.0 for Windows
    Oracle9i Database Release 2 (9.2.0.3.0) Patch Set for Windows

  • How to create connection to cluster of Oracle database server?

    Hi, all!
    I have to create connection to Oracle cluster. How to do that?
    I can make a connection to one server but to cluster ....
    I saw many documents but without any result.

    Hello
    Two servers with oracle database server installed organized as a cluster.
    Both server work in parallel, when one of them stop work the other takes connection automaticaly.
    The connection to the cluster is not usual as a one server.
    I have to specify both servers.Any time i can make a connection to one of them but when he stop work my connection will be broken.
    Because of that the servers work under oracle server software.
    So i can make a connection to one of them and both.
    This is made because it is for production firm with many test computers that work 24/7 and send information to this oracle server.
    So i have to make a connection to the general oracle cluster (the two servers simultaneously).
    I saw some connection strings to do tha written on Visual Basic but i have no idea how to do that in C/C++.
    There is no information about that in the Oracle tutorials and manuals.
    I need this explanation because i make a connection without TNS config file.
    Can you help me?
    I will be very appreciated.

    Is there a newer release of Oracle database server 10g which supports SLES 10 SP2? A download link would be of great help.
    Thanks,
    Ashutosh

    Some suggestions.
    Edit /etc/SuSE-release to say:
    SUSE Linux Enterprise Server 9 (i586)
    VERSION = 9
    Change it back after Oracle 10.2.0.1 is installed & before applying latest 10.2 patch.
    Install the 'orarun' SLES package. (yast as root - Before Oracle Install)
    I also install 'gvim' 'Gnu C compiler' & ' Sun Java 1.4.2'. (also, yast as root b4 Ora install)
    Then load latest OPatch for 10.2.0.? (Patches are OK with SLES10 in 'release' file)
    Then latest CriticalPatchUpdate.
    I've had a long battle - and won - , getting 15GB SGA's running on 32bit Linux.
    Use 64bit hardware and OS and Oracle if you have a choice. Much simpler.
    Regards, Vin.

  • In TestStand 2.0, will a record be lost if an Oracle database server is down? Can it be written to a file to be entered later?

    I currently have TestStand 2.0 setup to log information to an Oracle 8i server located on a network. Everything works correctly; however, if I lose the network connection, what happens to the database record that is,or would be, created? Is it lost? Can it be saved to a file and entered into the database at a later date?

    TestStand has no built in mechanism for handling a database that is offline. The logging sequence will generate an error if it is unable to write. You could modify the sequence to trap the error, write to a backup file, and then transfer the records when the database is back on line. What we're implementing here is to always write to a local database and an ActiveX component running in the background transfers records to the network database when it is available.
