Use jcmd <PID> GC. Though both -Xms and -Xmx JVM options are used to specify the size of heap memory, main difference between them is that -Xms is used to specify initial heap memory while -Xmx is used to specify the maximum heap memory. The -Xmx argument specifies the maximum size of the heap, not of the total memory used by the JVM. It's recommended to set these values to be the same so the heap size isn’t contracting and expanding during the life cycle of the JVM — as resizing takes up overhead and can decrease overall performance. Step 6 - Replace 2G with how much RAM you want to allocate (e. Not sure how much default is defined for heapsize? How much maxpermgen and xmx values are permitted for a given RAM (2gb/4gb)?
