Error description

• PE33763-F802
  After applying PTF UK33763 for APAR PK56985 if an abend occurs
  in a task and transaction isolation is active ( TRANISO YES is
  specified in the CICS SIT ), the following messages may be seen
  in the CICS region:

  If the abends continue to occur at a high rate, you may also
  receive the following messages in MAS or CMAS:
  .
  EYUXC0023S applid Maximum data cache limit has been reached
                    for QUE cache
  EYUXC0024S applid   The CMAS is terminating due to a previous
                      error with the Cache component
  .
  MAS method NLS4 is called to process XSTOUT in error.  EYU9NLDC
  XDUREQC GLUE uses R6 for an XPI call to SM domain for TRANISO
  processing and then uses R6 again later to set XMEMSG_ACTION in
  the message bucket.  The XPI parmlist is later interpreted by
  MAS method NLXD as an XSTOUT request resulting in the abend.
  Method NLS4 has created a work queue but does not delete the
  work queue if an abend occurs.  If many abends occur, the
  EYUXC0023S and EYUXC0024S messages may occur for the QUE cache.

  ****************************************************************
  CPSM uses CICS Global User Exit (GLUE) programs to capture CICS
  processing information, place it in a buffer, and post method
  EYU0NLXD (NLXD), running under the MAS long running task CONL,
  to process.  For example, EYU9NLDR, running as an XDUREQ GLUE,
  captures Trandump and Sysdump start, while EYU9NLDC, running as
  an XDUREQC GLUE, captures Trandump and Sysdump complete.  These
  buffers include a flag (XMEMSG_ACTION) which indicates what kind
  of information is in the buffer, so that NLXD can determine how
  to process the data.
  
  When NLXD receives a Trandump or Sysdump start, it builds an
  EMASSICK record which it passes to the CMAS to which the MAS is
  connected.  This will cause the CMAS to issue a !!SAMTDM or
  !!SAMSDM event if RTA SAM is active for the MAS.  Additionally,
  if the MAS is a CPSM WLM target region, WLM will mark the MAS as
  being sick, lowering the probability that transactions will be
  routed to it.
  
  When NLXD receives a Trandump or Sysdump complete, it builds an
  EMASWELL record which it passes to the CMAS to which the MAS is
  connected.  This will cause the CMAS to resolve an outstanding
  !!SAMTDM or !!SAMSDM event if RTA SAM is active for the MAS.
  Additionally, if the MAS is a CPSM WLM target region, WLM will
  mark the MAS as being well, increasing the probability that
  transactions will be routed to it.
  
  UK33763 added code to CICSPlex SM GLUEs to switch to CICS
  BASESPACE mode when transaction isolation is active in the MAS,
  to avoid possible AKEB/S202 abends.  In the code that was added
  to EYU9NLDC, the contents of the XMEMSG_ACTION flag passed to
  NLXD was invalidly modified.  As a result, NLXD may not process
  a Trandump or Sysdump complete correctly.  This will result in
  EMASWELLs not being issued for previous EMASSICKs, and possible
  other problems, including abends in method NLS4.
  

Problem conclusion

• EYU9NLDC has been updated such that the XMEMSG_ACTION flag that
  it passes to NLXD is not invalidly modified by the processing
  added for UK33763.
