You can retrieve statistics for public JVM programs by using the EXEC CICS
EXTRACT STATISTICS JVMPROGRAM system command. They are mapped by the DFHPGRDS
DSECT
JVM program resource statistics for public JVM programs show information and statistics
about each public JVM program, including the JVM profile that is used.
Statistics
for public JVM programs are mapped by the DFHPGRDS DSECT. For private JVM programs for
applications that are deployed on platforms, these statistics are mapped by the DFHPGPDS DSECT,
which has information about the application for which the JVM program was defined. For details
of the DSECT and DFHSTUP report for private JVM programs, see JVM programs - Private: Resource statistics.
JVM programs that
are defined as application entry points are identified by the PGR_JVMPROGRAM_ENTRYPOINT field.
Both public and private statistics records are written for these programs, mapped once by each
DSECT.
