You can use the EXEC CICS
COLLECT STATISTICS command,
or the
CEMT PERFORM STATISTICS command, with the
JVMPROGRAM option, to collect statistics on Java programs that run in a JVM.
(CICS does not collect statistics for these programs when a COLLECT or PERFORM
STATISTICS PROGRAM command is issued, because the JVM programs are not loaded
by CICS.) The JVM program statistics show, for each program:
- The JVM profile that the program requires (as specified in the JVMPROFILE
attribute of the PROGRAM resource definition).
- The execution key that the program requires (CICS key or user key, as
specified in the EXECKEY attribute of the PROGRAM resource definition).
- The main class in the program (the Java class whose public static
main method is to be invoked, as specified in the JVMCLASS attribute
of the PROGRAM resource definition).
- The number of times that the program has been used.
“Interpreting JVM statistics” in the CICS® Performance Guide has
more information about JVM statistics, and tells you how to find the full
listings and reports for these statistics.
