Error description

  • You are running CICS V3R1 with CICSPlex SM, and during normal
    operation, you terminate the logger with FORCE IXGLOGR,ARM.  The
    CMAS terminates due to the logger outage, and requests LRT
    termination of the MASes and WUI.
    .
    The CMAS attempts to restart immediately due to automation, and
    afterward, the WUI LRT termination completes.  The CMAS
    connection completes, but a series of ABEND 067/AKEB conditions
    ensue.
    .
    The ABEND 067 indicates 'An access register translation
    exception' in XSRR.  The MAS is trying to access a queue
    dataspace that has been deleted by the CMAS' restart.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All CICSPlex SM V4R1M0 Users                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: A MAS may exerience abend ASRB/S0067 if *
    *                      the CMAS to which the MAS is connected  *
    *                      is terminated abnormally and restarted  *
    *                      before the MAS is able to terminate and *
    *                      enter restart mode.                     *
    *                                                              *
    *                      The abend will most likely occur in a   *
    *                      method called from method EYU0XQPQ      *
    *                      (XQPQ), and XQPQ will most likely be    *
    *                      called from method EYU0XMSM (XMSM) or   *
    *                      from method EYU0XZPT (XZPT).            *
    ****************************************************************
    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all MASes must be restarted.  Note     *
    *                 that the restarts do not need to occur at    *
    *                 the same time.                               *
    ****************************************************************
    When a CMAS terminates, any MASes that were connected to the
    CMAS will terminate their MAS agent and enter restart mode.
    During this time, the MASes will issue messages and may issue
    exception or level traces:
    
    -  As part of message processing, XMSM will call XQPQ to write
       the message to the CMAS's consolidated message log queue, so
       that the messages can be written to the CMAS's EYULOG.
    
    -  As part of trace processing, XZPT will call XQPQ to write the
       message to the CMAS's MAS trace processing queue, so that the
       messages can be written to the CMAS's auxtrace datasets.
    
    Even though the CMAS has terminated, the queues will still exist
    and be accessible to the MASes.
    
    When the CMAS restarts, the storage areas where the queues
    reside are freed.  If the MAS is still issuing messages and/or
    traces while terminating and entering restart, abends may occur
    when XQPQ calls a method that attempts to access the freed
    storage.
    

Problem conclusion

  • Method EYU0NLRT (NLRT) has been updated to clear the ID of the
    consolidated message log queue token from the MSG component's
    major obect environment block (MOEB) and to clear the ID of the
    MAS trace processing queue token from the TRC component's MOEB
    prior to starting the termination and restart processing.  When
    the tokens are cleared, XMSM and XZPT will not call XQPQ to
    write to the queues.
