Error description

  • A JVM server is stuck in a disabling state as a result of the
    following exception during
    
    Liberty startup joblog :
    JVMSERVER XXXXXX is now enabled and is ready for use.
    JVMSERVER XXXXXX is being disabled due to a PHASEOUT
    request.
    
    In the JVMLOG:
    java.lang.Exception: Server has not responded within xxxxx
    milliseconds
    
    This JVM server causes the subsequent shutdown of the CICS
    region to hang..
    

Local fix

  • Set a larger timeout value for:
    com.ibm.cics.jvmserver.controller.timeout=e.g. 600000 (10 mins)
    to allow the Liberty server to start normally.
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICS Users                               *
    ****************************************************************
    * PROBLEM DESCRIPTION: CICS Liberty JVM server fails to start  *
    *                      within the set timeout limit and        *
    *                      CICS attempts to disable it using       *
    *                      a PHASEOUT but the JVM server remains   *
    *                      in a DISABLING state.                   *
    ****************************************************************
    There is a timing window within which if a Liberty JVM server
    exceeds the startup timeout value (determined by property:
    -Dcom.ibm.cics.jvmserver.controller.timeout), the PHASEOUT
    process fails to complete leaving the JVM server in a
    DISABLING state.
    

Problem conclusion

  • CICS has been change so that PURGE, FORCEPURGE and KILL will
    be used if necessary to ensure the JVM server is disabled.
