Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICS users.                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: When a JVM server is disabled whilst    *
    *                      non daemon threads are outstanding it   *
    *                      may hang with no output to the user.    *
    ****************************************************************
    When a JVM server is disabled when there are outstanding
    non daemon threads, it will hang and wait for these
    threads to finish their tasks. This can mean the JVM server will
    not disable if the threads are not completed in a set time.
    Without SJ domain tracing enabled, it is not clear to the user
    why their JVM server is hanging during shutdown.
    

Problem conclusion

  • CICS has been updated to display information in the
    JVMLOG/dfhjvmlog about any non daemon threads that may be
    causing a JVM server shutdown to hang.
