TOMCAT 6.0.32 with 64bit JDK?

Post by mikmartn »

Hi all,

We have been running TOMCAT 6.0.32 for years with the z/OS 31bit JDK. When we recently upgraded from JDK 6 to JDK 7, we occasionally get an OutofMemory condition when we recycle TOMCAT (a second recycle is usually successful).

I am wondering if we can just use the 64bit V7 JDK to gain more heap memory and avoid this memory condition.

Does anyone have any thoughts about us switching our existing TOMCAT from 31bit to 64bit, using the same TOMCAT? (we don't currently have plans to upgrade TOMCAT)

Have you looked at your max heap size?
