    Unhappy Unanswered: Oninit consumes a lot of memory

    Hello all,

    When I was checking the usage of resourses of our servers I saw that the oninit.exe use more then 1GB of the memory.

    As far as I can see informix runs fine. (and the server too)

    because I don' t have much knowledge of Informix, I put the question here.

    More information:
    Windows 2000 server
    Informix version
    Oninit.exe = Created: Tuesday, June 19, 2001, 11:49:32 PM

    If you need more information please let me know

    Can anyone help me.

    Hi Teun,

    This situation is pretty normal. In windows the oninit process contains all memory from the engine like:
    - Buffers (data caching)
    - Session info
    - Locking table
    - Sort pools etc.

    All of this is configured in your onconfig file which you can find in the etc directory of your informix dir. You can check the onconfig.servername file with an editor. Here you will see the number of buffers (in 4KB pages), shmvirtsize and shmadd. These parameters will influence the size of the memory a lot.

    Hope this helps,

    Rob Prop

    Post What are the effects of it?

    Hi Rob,

    Thank you for the reply, but if I change the settings does it make the database slower or are the other effects.

    Is it neccecary to restart the services of informix to make the settings work.
    (I suppose it is.)

    thank you in advance.
