Subject [jira] Commented: (JS2-1072) Jetspeed 2.1.1 getting out of memory.
Date Mon, 09 Nov 2009 08:08:32 GMT

    [ https://issues.apache.org/jira/browse/JS2-1072?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12774890#action_12774890
] 

Randy Watler commented on JS2-1072:
-----------------------------------

Another possible option available since Java 1.5_07 is to have the JVM dump a full heap file
on an OOME using these options:

-XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=<hprof output file>

One can process the generated hprof file using a HAT tool to get the same summary information
that would be generated by the control+break and the -XX:+PrintClassHistogram option

> Jetspeed 2.1.1 is configured with MSSQL and is throwing out of memory with 13 users.
The jetspeed was throwing this exception even with derby database then we decided to move
to MSSQL. The customer has 20 portal application and around 13 users working as of now.
> Can you give us the guidelines for the performance improvement for jetspeed 2.1.1. so
that we can remove this out of memory exception.
