[rules-users] Recommended permgen settings for Guvnor

[Clint Brown]

Hi,

We're using Drools Guvnor 5.0.1 in a production environment, running on 
Oracle's OAS10g 10.1.3.3.0 application server.  We're experiencing permgen 
issues, particularly when doing large imports of rules, archiving, or 
compilation of rules. 

We initially deployed to production with the following permgen settings: 
-XX:MaxPermSize=128M -ms128M -mx256M 

Following permgen exceptions, we increased the permgen to :
-XX:MaxPermSize=256M -ms128M -mx256M.

This sustained us for a while, but our assets are ever growing, and again 
we're exceeding the permgen space allocated.  Can someone recommend 
appropriate setting, particularly if you are using Guvnor to this 
capacity?  Is there a close correlation to the number of assets within 
Guvnor to the memory needed, so that we can project our future memory 
requirements?

Assets in Guvnor:
~ 1000 rules in 5 decision tables (.xls) in 5 separate packages
~ 125 technical rules (drl)
~ 5 Guided editor rules

Thanks,
Clint
