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 ______________________________________________________________________________________ Clint Brown | Programmer Analyst II (Advisors) | o: 512.683.5232 | m: 512.736.6337
