--------------------------------------------------------------
Hi,
I have a jboss 5.1 app with sun jdk 1.7.something. At night, it runs a large job and gobbles memory. The process gets to 2.5GB and never goes down, but I hear that's normal with heap space? But after a few days of this, I begin to see the cpu spike to 100% of one cpu for a few seconds, then go down. This happens every 5 seconds or so, probably GC?
Using mostly a default run.bat, I have the jvm args set to:
-Xrs -Xms256M -Xmx2048M -XX:MaxPermSize=256m -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC
-Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000
-Dorg.jboss.resolver.warning=true
Should we be doing something more specific? And if the GC keeps running that often even after the thread to do the nightly job has ended, do I have a memory leak somewhere? We do sometimes run out of memory, but maybe it needs Xmx of 4gb just to finish the job.
I'm going to up the memory anyway, but what clues do we look for to determine if there is a leak and/or better GC settings?
Thank you very much!
Jim

--------------------------------------------------------------
I make JSF beginner's aplikacation and goal is that with index.html simply present the content of database table.
I make customerBean.java for connecting and read content of datatable.
I handling connection over datasource:
Database is Derby .
I made datsourc in jboss7.1 standalone and I can ping database.
@Resource(name="java:/MyDerby", type=DataSource.class)
private DataSource ds;
Is it correct that JDNI for @Resource written above?
I made datsourc in jboss7.1 standalone and I can ping database.
But when I start aplication on server I have got error on web server with code http status 500.
