Error description

• PTF UI32246 for APAR PI44085 is not working. This APAR allows to
  customer, using CHISERVP parameter, remove some error messages
  from CHIN log (CSQX053E and CSQX504E) in WMQ for z/OS Ver.8.0.
  But, with the PTF applied and the CHISERVP parameter correctly
  set, the error messages and CSQSNAP FFST entries are not
  removed from CHIN log.
  
  CHIN log shows the CHISERVP is correctly set, but also shows
  messages CSQX053E and CSQX504E:
  
  ----------------------------------------------------------------
  +CSQX053E ?QSM CSQXFFST Error information recorded in CSQSNAP
  data set
  +CSQX053E ?QSM CSQXFFST Error information recorded in CSQSNAP
  data set
  +CSQX504E ?QSM CSQXRESP Local protocol error,  567
   channel JMS.ATG.COMMERCE
   type=0000000B data=00000000
  ----------------------------------------------------------------
  
  And CSQSNAP shows Eyecatchers:

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 *
  *                 Release 0 Modification 0.                    *
  ****************************************************************
  * PROBLEM DESCRIPTION: When a Java client at version V7.0.0.0  *
  *                      connects to a V8.0.0 z/OS queue manager *
  *                      an MQOPEN of a queue will fail with     *
  *                      'CSQX504E Local protocol error'.        *
  *                      APAR PI44085 attempted to address this  *
  *                      issue but did not provide a complete    *
  *                      fix.                                    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The Java V7.0.0.0 code does not send a valid flow for the MQOPEN
  API call. This invalid data is tolerated by V7.0.1 (and V7.1.0
  with toleration PTF enabled) queue managers, but at V8.0.0,
  additional tests will detect the invalid flow and terminate the
  channel connection, reporting a CSQX504E error. In addition an
  FFST is captured on the z/OS server side indicating
  "rriBadDataReceived".
  
  This issue is addressed in the Java Client Fix Pack 1
  (V7.0.0.1 and above), but it may be impractical for a customer
  to deploy the client-side fix throughout their enterprise.
  

Problem conclusion

• Following the application of the PTF for this APAR, customers
  may elect to enable less stringent checking of MQOPEN flows from
  clients to prevent the failure from occurring on the server.
  
  This checking will only be disabled when activated using the
  appropriate CHISERVP service parameter under the direction of
  the IBM MQ Support team. Without this activation, the
  server behavior will remain unchanged.
  
  Please contact IBM MQ Support if you wish to activate this
  capability.
