PH37147: MAS REGION IS NOT REGISTERED TO A CMAS WORKLOAD AFTER CHANGE IT FROM LPAR. MESSAGES EYUNL0160I & EYUWI0020I ARE NOT ISSUED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MAS region that is not registered to a CMAS workload after
  change it from an LPAR to another. The registration only happens
  when customer use COSH/COLM transaction.
  
  MAS log the following messages are issued when it is connected
  to CMAS:
  
   EYUCL0012I Connection of XXXXXXX to YYYYYYYY complete.
   EYUTS0003I Topology Connect for XXXXXXXX Complete - APPLID
              (XXXXXXXX) CICSplex(ZZZZZZZZ).
  
  But messages:
  
   EYUNL0160I Workload registration complete.
   EYUWI0020I WLM Routing initiated for workload(WWWWWWWWW) in
              Routing Region(XXXXXXXX)
  
  are not issued until you use COSH/COLM transaction. It is not
  the expected behaviour.
  

Local fix

• Use COSH/COLM transaction to complete the Workload registration.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS CPSM users                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: A MAS is shut down, and restarted.      *
  *                      During the restart the MAS connects     *
  *                      to a different CMAS from where it       *
  *                      was previously connected.               *
  *                      The MAS does not connect to             *
  *                      workload manager as a routing region.   *
  ****************************************************************
  * RECOMMENDATION: Apply the fix and recycle CMASes in any      *
  *                 order when convenient to implement.          *
  ****************************************************************
  When a CMAS performs a CPSM CMAS warm restart, it sets all the
  MASes it knows were previously attached to other CMASes to
  lost connection status. It does not note if these MASes were
  stopped prior to the point where the CMAS was shut down.
  If one of these MASes then restarts and connects directly
  to this CMAS then WLM restart is not performed, and the
  MAS does not rejoin the workload.
  Messages EYUNL0160 and EYUWI0020 are not issued by the MAS:
  +EYUNL0160I applid Workload registration complete.
  +EYUWI0020I applid WLM Routing initiated for Workload(workname)
   in Routing Region(sysname).
  

Problem conclusion

• The CMAS Topology warm restart code in method EYU0TIWS has
  been modified to test the last known state of MAS systems.
  This allows the CMAS to detect when a MAS has connected
  locally having previously been connected to a different
  CMAS. This allows for WLM restart to function as expected.
