Can I auto restart tomcat jvm on out of memory exception

Question

I know that this is not \"best practice\" but I would like to know if I can auto restart tomcat if my deployed app throws an outofmemory exception

Answer 1

You can try to use the OnOutOfMemoryError JVM option

-XX:OnOutOfMemoryError="/yourscripts/tomcat-restart"

It is also possible to generate the heap dump for later analysis:

-XX:+HeapDumpOnOutOfMemoryError

Be careful with combining these two options. If you force killing the process in "tomcat-restart" the heap dump might not be complete.
