JVM Configuration parameter -Xdisableexplicitgc

Question & Answer


Question

What is the purpose of the -Xdisableexplicitgc settings in respect to Maximo?

Cause

Customer has asked questions related to Garbage collection process

Answer

In Web Sphere triggering garbage collection could be done in two ways.

By the policy or explicitly by application. By default the parameter is not set and application may call System.gc() and trigger collection that will impact performance. -Xdisableexplicitgc will disable the garbage collection from the System.gc() call.


We recommend to include the parameter in JVM generic argument for Maximo application.
