Tomcat7/RHEL/Oracle JVM 1.7.0_80/Pega7.1.5/Oracle12c

Hello,

We are using below combination in our environment Tomcat7/RHEL/Oracle JVM 1.7.0_80/Pega7.1.5/Oracle12c.Our GC policy is -XX:+UseG1GC. -XX:ParallelGCThreads=4 -XX:ConcGCThreads=2.

Can you please let us know the ideal GC policy for the above combination?

I think the GC policy depends on number of factors and how your application is designed

So there is no ideal setting as such as discussed on various post, but you can check below links for reference.
