How aware is Oracle 9i/10g of multiple CPUs?

We currently have a SunFire V880 with 4 CPUs. There is a plan to purchase another 4 CPUs for that same box. I was wondering if there was an optimal configuration for Oracle (with regards to CPUs).
Can Oracle use that many CPUs?
Is there a limit to how many CPUs Oracle can use effectively?
During what circumstances does Oracle use multiple CPUs?

It's the operating system a lot more than Oracle that takes care of using the various CPU's in a system. If Oracle has more than 8 concurrent threads/processes (depending on the operating system), the operating system should ensure that all the CPU's are being used. In a dedicated server configuration, assuming you have more than 4 concurrent users, going from 4 to 8 CPU's may be beneficial. If you spend a lot of time doing single-threaded ETL, though, you may need to increase your degree of parallelism to use more than 1 CPU.

  • How to connect oracle forms 10g with oracle 10g express database?

    Hi all,
    I have downloaded and installed oracle forms 10g and oracle database 10g express, when I open net configuration assistant to test local net service, I tested the default service (EXTPROC_CONNECTION_DATA) BUT THE RESULT IS "ora-28547 connection to server failed probable oracle net admin error"
    How can I solve this issue?
    My tnsname.ora is located in c:\DevSuiteHome\network\admin\tnsnames.ora, and its contents is:
    # tnsnames.ora Network Configuration File: c:\DevSuiteHome\network\admin\tnsnames.ora
    # Generated by Oracle configuration tools.
    EXTPROC_CONNECTION_DATA =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = nour-pc)(PORT = 1521))
    (CONNECT_DATA =
    (SERVICE_NAME = PLSExtProc)
    Edited by: user10228498 on Jan 21, 2011 11:37 PM

    I copied the contents of C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN\tnsnames.ora and appended it to C:\DevSuiteHome\NETWORK\ADMIN\tnsnames.ora
    and tried net configuration management to test local net service, the test was ok, thus the first problem resolved.
    but the login problem in forms developer still exist and it claims that: ora-12154 tns could not resolve the connect identifier specified.
    any ideas?

  • How to Migrate Oracle Forms 10g 9.0.4 to 10.1.2

    Hi I would like to find information on what is necessary to do in order to migrate Forms 10g 9.0.4 to 10.1.2.
    Do I need to use Oracle Migration assistant ?
    Is it enough only compile forms ?
    Where I find documentation on how to execute this migration. I am only find documentatio to migrate from 6i to 10g, but I need documentation to migrate from Forms 10g 9.0.4 to 10.1.2.

    Hi,
    Thank you for the answer about Oracle forms.
    Now I would like ask another question but this time for Oracle Application Server. As we have Oracle forms 10g 9.0.4 we also use the Application Server with this same version.
    Do you have any recommendations on how to Migrate the Oracle Application Server from 10g 9.0.4 to 10.1.2 ?
    Thank you .

    The complete installation installation guide is included with the installation software. It is also part of the exhaustively complete documentation set for every oracle product found at tahiti.oracle.com. Go there, select your product and version. When you arrive at the page for your specific product version, somewhere on that page (location varies between versions) you will find a link to the installation guide.
    Also please note that there are several versions of Vista, and the Oracle db is not certified for all of them, but only for specific versions.

  • How to Install Oracle Forms 10g (9.0.4) Demos

    Hi.
    My forms version is :
    Forms [32 bits] Versión 10.1.2.0.2 (Producción)
    Oracle Toolkit Versión 10.1.2.0.2 (Producción)
    PL/SQL Versión 10.1.0.4.2 (Producción)
    I'm trying to install Oracle Forms 10g (9.0.4) Demos. Everything works fine until step 5. I can even access the forms demos home page(changing forms90 to forms). However when i try to access any link, i get the following error:
    404 Not Found Resource /forms90/f90servlet not found on this server
    What's wrong?. I believe forms is pointing to the wrong direction:
    http://mluis:8888/forms90/f90servlet?config=reusable_picklist
    For example to show the tick image on step five on install guide, I have to replace
    http://mluis:8888//forms90/formsdemo/images/tick.gif
    for http://mluis:8888//forms/formsdemo/images/tick.gif
    This is because I don't have a forms90 directory in my Oracle_Home. I changed forms90 for forms in formsdemo.env. But still doesn't work. So my question is
    - Are these forms demos built for my forms version?.
    - If not, what do i have to change in order to make things work. I'm really interested in some special features like PJC, Webutil etc.
    - The configuration is still pointing at a forms90 directory. I need to change it to just forms but don't know which files.
    Thanks in advance ...!

    Hi,
    Have you resolved this issue? I have gotten a bit further.
    You also need to change any f90xxxxxx to frmxxxxxx
    But the servlet cannot seem to find any of the demo forms.
    I assume a path issue, but cannot seem to find it.
    Any clues?
    Thanks.

  • How to Connect Oracle Database 10g with using Oracle Dev 10g

    Hello there,
    I have problem with connection on database 10g using oracle dev 10g on the same server.
    The message is: TNS... bla..bla... it means not connect.
    Please advice
    Regards
    Leksono

    just simple
    copy the from the database instance the tnsnames.ora
    file's entried into developer folders tnsnames.ora
    file and you can connect to DBFirst of all there is no such error as TNS... bla..bla... it means not connect.
    there are several errors for the tnsnames, post the exact error
    And it is not recommended that you copy it from the database's tnsnames file, it doesn't always work.
    to configure the tnsnames.ora you have 2 ways, manual and GUI.
    For GUI use the Net configuration assistance from your Devsuite home and for manual you need edit the tnsnames.ora file usually under %ORACLE_HOME%/NETWORK/ADMIN
    You need to specify the connection string name, the hostname and the database SID name. It should look something like this.
    <connection identifier> =
      (DESCRIPTION =
        (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = TCP)(HOST = host name)(PORT = 1521))
        (CONNECT_DATA =
          (SERVICE_NAME = SID)
      )Regards,

  • How to configure oracle listener profile for multiple oracle database

    Hi,
    I am going to install solution manager system in the same server of ERP EHP4 on Windows. Both DB are oracle.
    I'd like to know how to configure listener in this kind of envirnmonent.
    a. use two listener and different ports
    b. use same listener but different ports
    c. use same listener and same port
    Which is the correct mothed?
    And, after installation, there seem three set of profiles of listten, one for ERP, one for SLM, and the other for OS?(%windir%system32), which one is functional?
    Please advise.
    Thanks a lot.
    Regards,
    Alex

    Hi,
    standard installation is creating new configs for listener for each instance.
    I would recommend to use one listener per each instance.
    YOU CAN NOT HAVE one port number for two differnet systems!
    If you want to use one listener than you must adapt tnsnames.ora, listener.ora and ensure that both systems will use different port numbers.
    For example PORT= 15<system number>
