Orbeon application requires more memory on Weblogic 12c

Hi,

Does anyone know why the same application loaded in WL 12c requires more Perm Gen memory, loading more classes, than in WL 11g. A Orbeon application we deployed expend 25M PermGen in WL 11g but expend 140M PermGen in WL 12c.

I am using Orbeon Forms 3.7.0beta1.200808240812.

Thanks!

Hi James,

Hard to say; it might be because of the different JVM being used (6
for WL 11g, and 7 for 12c), or changes in the application server
itself. But we're still talking about a reasonably low amount of
permgen, so that shouldn't be a problem, right?

Thank you for your reply.

The issue is critical. WebLogic 12c crashes every time when I re-deploy the Orbeon application. WebLogic 12c is running on the same JDK 6 as WL 11g.

Please let me know if you have any suggestions.

Hi James,

Are you saying that the problem still happens after you extended the permgen?

No, I have to double the memory of PermGen to avoid the issue, even though memory is limited on server machine. I don’t understand why there is difference since the same Orbeon application is running with the same JDK 6 on WLS 12c

Hi James,

OK, good – in the sense that it works by doubling the memory allocated
to the permgen. Based on the information in your original message,
you're going from 25M to 140M, an increase of 115M. This seems to be a
trivial amount of memory to me, with servers (and even laptops)
shipping with GB of memory. If it is working by allocating such a
small additional amount of memory to the VM, I would personally shrug,
and assume that somehow the new JDK or WLS just needs more memory.
