Get metrics data failed. java.lang.OutOfMemoryError: Java heap space

  • 1.  Get metrics data failed. java.lang.OutOfMemoryError: Java heap space

    Hi all
           I'm trying to enable motorization for my environment using IBM DMC and it works fine until it has this message:
                   Get metrics data failed. java.lang.OutOfMemoryError: Java heap space

           Can someone tell me where I can enlarge this value?

    Hello Daniel,
    DMC is a little different compared to DSM.
    You will need to increase the following parameter in the jvm.options file:
    -Xmx2048m
    The default is 2 GB, but depending on how many databases you are monitoring, you will need to increase that number accordingly.
    For additional information, please refer to the following link:
    https://www.ibm.com/support/knowledgecenter/SS5Q8A_3.1.x/com.ibm.datatools.dsweb.ots.upgrade.doc/topics/postupgrade.html

    Currently we don't have a capacity planing document for DMC, my recommendation is to use the one for DSM instead for now:

    I hope that helps!
    Please let me know.
