    --------------------------------

    As above

    I am a bit confuse about the

    Application servers > AppSrv01 > Process Definition > Environment Entries > Java Virtual Machine

    Initial Heap Size and Maximum Heap Size

    If is set both (post_id, thread_id, post_subject, post_timestamp, post_content) VALUES to be the same say 256mb

    will my java.exe always be 256 regardless ?

    A little google would save you some time.

    Initial Heap = starting heap size
    Mac heap = maximum value the heap can reach

    As for setting them the same, that depends on the version of the SDK you are running and on what platform your are running on.

    Setting the heap size of your application is not a trivial task!
