The default for this is normally adequate and you shouldn't need to change it.

Hey...I was also trying the 'minimumHeapSize' attribute to change the minimumHeapSize as well, but did not work..any corrections, pls suggest? Thanks Very well explained!

I have a very large topology using XD. One Dynamic Cluster and one standard cluster. I would like to change the MaxHeap for 'all' JVM's in the standard cluster. For instance the dynamic cluster members are named something like: XXX-A01-SIS-xxxx and the standard cluster is XXX-A01-XES-xxxxx. Is there a way for instance to use grep w/ the python script? Is this possible? Also where I can find a list of I can list w/ AdminConfig.list like in your example where you used JavaVirtualMachine? Is it possible to pass the list of servers through grep?

You might find this does the job, I haven't used it: http://www.alphaworks.ibm.com/tech/gcdiag?open&S_TACT=105AGX59&S_CMP=GR&ca=dgr-jw26awgcdiag.

What I am looking for is to now 'list' all the HEAP for all the JVM's in my cluster. I would really like to be able to list what is actually being used. Is that possible?
