    Ofcourse not, but depends on what kind of DB u have designed .. ( OLTP or DW ).

    In dedicated mode, each user process will have a dedicated conn to the server.

    In MTS mode, you can imagine like a multiplexing kinda concept..

    RTM and understand why the parameters that u specifed before were causing porblems.. and how its related to MTS/Dedicated.

    Its basically a 3 tier system , so around 400 clients access the database ,and commit or rollback their data , so creating a dedicated conn create any resource problems ...

    Thank you for solving the issue

    It is still unclear if you have a large_pool_size of 0 or not.

    Run: conn / as sysdba

    and then:

    show parameter large

    More important: you have a non-patched version of Oracle 9iR1. Having a possible memory leak is more than normal.

    Dear Julian


    I ran the show parameter large in sqlplus

    its gave this

    Large pool size 7048560


    More important: you have a non-patched version of Oracle 9iR1. Having a possible memory leak is more than normal.


    So what to do regrading the patch , whats the patch number so that I can run the patch...

    Regards,
    Ramesh.M

    7M is a small value for the large pool. I assume that you are having a memory leak/bug because of using a basic version.

    Apply patch 9.0.1.5.0. You can dowload it from Metalink.

    Not Necessarily. He needs to see how much PGA each session takes. Add it up and see how much Memory it is, because that's in addition to the SGA. I once had an app that had less than 50 connections, but each one was taking ~25Meg. (I know, bad app.. but I couldn't change it) The Machine only had 2 Gig of memory. I was swapping like CRAZY. Switched to MTS, no more problems.

    Just an FYI...
