    Unanswered: DB2 diag.log error

    Hi all,

    We are using DB2 V8.1 and Fixpak 6 and OS-AIX 5.2. I am getting the following error in the DB2diag.log in one of my server.Need a help in finding the root cause of this error and its solutions.

    Error
    Reserved heap size exceeded for Database Monitor Heap (MON_HEAP_SZ) on node 0,
    allocating additional unreserved memory.

    Any help.

    Thanks

    It is saying that your DBM parameter MON_HEAP_SZ is to small for your server. Although DB2 will get any additional memory needed for monitoring from unreserved memory, you should increase this because you may end up with a situation where there will be no unreserved memory.
