Other profiling options

TACL command status can be used to obtain the detailed status of application, including the process time of a Java process. Also, PSTATE tool can be used to get details about the Java process.

In NSJ, if Parallel or CMS GC (deprecated in NSJ 11) is enabled, a Java application consists of a Java process group that includes the Java process and javahelper processes. If parallel or CMS GC is enabled, run the TACL command status and PSTATE/PSTATE2 tool individually for the Java and the javahelper processes. To obtain all the javahelper processes for a Java process, nsjps can be invoked with -gc option. For information about nsjps, see NSJ 11 Tools Reference Pages.

Also, the C heap usage reported by PSTATE tool for an application running with NSJ 11 will be lesser than C heap usage reported when the same application is run with NSJ6. This is because most of the JVM allocations and the Java heap are moved to flat segments in NSJ 8.0 and later versions.
