Increasing Heap Size on NCM

Increasing Heap Size on NCM

Has anyone have issues with the low heap size on NCM? It's showing me it uses about 600MB while it only has 100MB heap size.

I tried tuning the heap size by executing the -Xms and -Xmx commands but it looks like it needs to point to a certain java "object" (or script? not that familiar with JVM).

Wondering if anyone have any experience tuning the heap size and can share the command line they used.

Thanks
