JVM programs - Public: Resource statistics

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.
