OA59371: MQ INTO CICS: APPD TOKEN TRANSPARENCY

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• Currently, a customer who wishes to monitor their MQ/CICS
  applications may need to make application changes if they
  do not support RFH2 headers in a message. This fix will allow
  the use of old applications that do not specify any
  GMO properties (compiled with older unsupported versions of MQ),
  or that mark the queue with "PROPCTL=NONE" while using the
  default GMO properties or MQGMO_PROPERTIES_AS_Q_DEF and zAPM
  will save the RFH2 header from the message allowing zAPM Connect
  to monitor the subsequent call in CICS.
  
  This does not work for applications that put directly to
  an MQGET using the "fast put to waiting getter" configuration.
  
  This update will also improve the performance of MQ into CICS
  transaction flows in zAPM and may also solve a storage overlay
  

Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED: All zAPM users with MQ/CICS applications     *
  *                 without support for RFH2 headers on messages *
  ****************************************************************
  When AppDynamics inserts an RFH2 header on a message, some
  applications will fail unexpectedly, sometimes with an abend 0C7
  in CICS. zAPM also may cause a significant increase in CPU usage
  for some transaction paths.
  

Problem conclusion

• The product will now save the AppDyanamics header from the
  message if it has no GMO (Get Message Options) Properties set
  (this is true with older MQ versions) or the queue specifies a
  PROPCTL=NONE and GMO Property is MQGMO_PROPERTIES_AS_Q_DEF or
  MQGMO_NO_PROPERTIES. Storage handling has also been improved to
  reduce CPU usage and solve a potential overlay.
