WebSphere JVM memory

the WAS started to load very slow and keep hanging for whatever actions selected, end with a “java.lang.OutOfMemoryError” error message in the WebSphere’s log file.

The default WebSphere’s Java Virtual Machine memory is not enough; you should adjust more memory to your WebSphere Application Server. See following guide to increase WebSphere’s JVM memory.

1. In WebSphere web console, select Servers -> Server Types -> WebSphere application servers -> Server Infrastructure -> Java and Process Management -> Process definition.
WAS-adjust-memory-1

In Additional Properties section, select Java Virtual Machine

WAS-adjust-memory-2

In General Properties section, put 256 for “Initial heap size” and 1024 for “Maximum heap size”.

WAS-adjust-memory-3

Done, restart WebSphere.
