Subject: Re: Maximum Deployment Size? was (RE: Cluster SynchronizationException)
Hi,
the problem may (I had similar issues in the past) be caused by the fact
that the node agent spawns a JVM for the sync process and uses the
default Xmx heap settings for that jvm. If you specify a larger setting
the issues should go away. So for syncing larger apps in a clustered or
distributed environment you should apply the following settings for each
node agent:
asadmin set domain.node-agent.<node-agent-name>.property.INSTANCE-SYNC-JVM-OPTIONS="-Xmx256m"
Using -Xmx256m for 256m max Heap is just a suggestion over the jvm
default. In my deployments that was sufficient to also sync apps with
over 50m .ear files.
Please have a look at:
