  • Closed as program error.

Error description

  • For situations of frequent Agent logons, such as IDAA customers,
    it is possible that an Agent connection request arrives before
    the shutdown is issued, but its processing is handed to the next
    stage task after the shut down has started.  This can leave the
    Agent initiation request stalled.  This will inhibit the
    conclusion of shutting down the address space.
    The processing load on the system is probably a factor in the
    probability of this occurring.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of IIDR CDC for z/OS who frequently    *
    *                 log on to a configuration agent and log off  *
    *                 again.                                       *
    ****************************************************************
    * PROBLEM DESCRIPTION: During Agent logon processing, it is    *
    *                      possible that an Agent logon request is *
    *                      accepted just before the address space  *
    *                      is being shut down.  If the connection  *
    *                      to DB2 is then terminated before the    *
    *                      logon completes, the Agent connection   *
    *                      can remain partly processed, and will   *
    *                      then inhibit the termination of the     *
    *                      communications component of the address *
    *                      space.  The address space will remain   *
    *                      up until it is cancelled.               *
    ****************************************************************
    * RECOMMENDATION: APPLY CORRECTIVE SERVICE                     *
    ****************************************************************
    Frequent Agent logons can render the address space unable to
    shut down.
    

Problem conclusion

  • Accounting of the pending Agent connections will be corrected so
    that the address space will be able to detect and terminate them
    during shut down processing.
