Cross Reference Option
NSJPS provides -x option that prints the parent-child Java process relationships.
This helps to identify the child Java processes started by a particular parent process.
In the cross reference listing, only the Java processes are considered and not the
GC processes. The following example shows the usage and output for -x option.
nsjps —x

Output Options
The output options are used to print details such as, PIN, User ID, and process ID on the selected
Java processes.
Heap Sizes
NSJPS prints the heap size only in bytes. Therefore, even if the heap size is large,
for example 24 GB, NSJPS displays it as 25769803776 bytes. Note that with
NSJ7, the heap space required for JVM and Java heap are allocated from flat
segments and the size output of a Java or GC process includes the size of these
segments in addition to the native C-heap. The following example shows the usage
and output for -h option:
/home/daya/ACC/nssjava/jdk170_h70/bin/nsjps -h
PID Cmd Heap
16777243 java 377126912
-h option
If —h option is used with —gc option, then the heap size for each process in the
Java process group is listed separately. The following example shows the usage
and output for -h option:
nsjps —h —gc

-l option
This option lists the Java or GC process command in long format. The following
example shows the usage and output for -l option:
nsjps —l
