Many users restrict the Java heap size to 2-8 GB in order to minimize garbage collection pauses. Change the bump pointer space size to be as large as the heap capacity instead of 1/2 heap capacity like it used to be. For GSS, bump pointer spaces are set to 32MB currently. Changed GSS to have main space == non moving space since we don't need to copy from the main space. Heap dumps contain a snapshot of all the live objects that are being used by a running Java application on the Java heap. We can obtain detailed information for each object instance, such as the address, type, class name, or size, and whether the instance has references to other objects.java -Xmx1024m this means the java application can have maximum of 1024 Mega Bytes of Heap. If you don't know the maximum heap size for your application, check the command line of your java application to locate the -Xmx option. There are quite a few ways you can capture the heap usage.
