PM96272: WMQ AFTER MIGRATION TO VERSION 7.1 PUTS BY APPLICATIONS TO CLUSTER QUEUES FAIL WITH MQRC 2087

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The problem appears to be caused by uninitialised data in one of
  the calling programs (CSQMORQ1). Note that subsequent runs of
  the application program(s) results in the PUT completing
  successfully.

  ****************************************************************
  A queue-remote specifies a clustered queue manager in the
  RQMName field. When an application puts to this queue CSQMORQ1
  invokes CSQMZLOO to find the clustered queue manager, passing
  lLookupOpts as one of the parameters. This value should only be
  2 or 6 in CSQMORQ1. In V710 CSQMORQ1 generates lLookupOpts
  by ORing, however if the value was not correctly initialised to
  zero then CSQMZLOO will receive a bad input parameter which will
  usually result in the cluster queue manager not being found and
  therefore a RC=2087.
  

Problem conclusion

• CSQMORQ1 has been changed to initialise lLookupOpts to zero.
