Error description

• While in the process of upgrading to CPSM 6,1, the CMAS has been
  upgraded to 6.1.  The MASes were upgraded to CPSM 6.1 while
  running CICS 5.6.  Now during start up the EYUCS0207W and
  EYUCS0208I messages began to appear in the log for some of the
  MAS regions:
  
  EYUCS0207W applid Connected MAS CICSMAS is not responding -
  APPLID(CICSMAS) CICSplex(CICSPLX).
  EYUCS0208I applid Connected MAS CICSMAS is now responding -
  APPLID(CICSMAS) CICSplex(CICSPLX).
  
  The MAS CICSMAS was deemed non-responsive shortly after the TOP
  Connect was completed to the CMAS.  From a CICS perspective the
  region was not hung or looping.  The MAS did receive the MOS
  NQCR MAL from the CMAS.  But when it tried to tried to return
  the MAL to the CMAS it failed with these exceptions:

  The MAL failed to be returned to the CMAS with its response.
  This failure in CAMR is what caused the CMAS to think the MAS
  was unresponsive.  This failure occurred running the COIR task
  which is the RTA EVALDEF task.
  

Local fix

• This issue only occurs when the RTA configuration has the
  separate task indicator (SEPTASK) set to YES on the evaluation
  definition (EVALDEF). Setting this to NO should bypass the
  issue, though it will change the behavior of the evaluation,
  with it running on the MAS LRT (long running task) rather than
  running on a separate task which is started for the evaluation.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICSPlex SM Users.                       *
  ****************************************************************
  * PROBLEM DESCRIPTION: A CMAS may report a MAS region as       *
  *                      unresponsive with message EYUCS0207W or *
  *                      the MAS region may abend ASRA in CAMR.  *
  *                      when a MAS resource monitoring (MRM)    *
  *                      evaluation definition is defined for a  *
  *                      CICSRGN resource.                       *
  ****************************************************************
  * RECOMMENDATION: Apply PTFs to all CMAS and MAS regions.      *
  *                 This may be performed in any order.          *
  ****************************************************************
  Real-time analysis (RTA) MRM evaluation definitions can be
  configured to monitor the CICSRGN resources. The requests to
  inquire these resources are sent to the appropriate MAS regions.
  The inquire for this resource is handled by EYU0NQCR. However
  logic to convert time values for the resource may overlay
  working storage.
  
  As a result, if the evaluation definition has the separate task
  indicator set, the field, KOPB_OACB_MPFX, required to reply to
  the request may be overlaid. With the incorrect value in
  KOPB_OACB_MPFX, the function to reply to the CMAS, CAMR may
  fail. The CAMR call may fail with reason METHOD_FAILED, or
  a 0C4 abend occurs in CAMR, which results in the MAS abending
  ASRA in CAMR (ASRA with SCODE=S00C4 TRAN=COIR). The failure in
  CAMR prevents the CMAS receiving the required response,
  resulting in the CMAS reporting the MAS as unresponsive with
  the following message:
  EYUCS0207W applid Connected MAS CICSMAS is not responding -
  APPLID(CICSMAS) CICSplex(CICSPLX).
  

Problem conclusion

• The convert time logic in EYU0NQCR has been corrected to
  address the overlay, to allow CAMR to respond correctly.
