PM78113: CSQE020E IS GENERATED AFTER MIGRATION TO WEBSPHERE MQ V710 WHEN QMGR BEGINS STARTUP OR IS NOTIFIED OF CF RESOURCE AVAILABILITY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After migration to WebSphere MQ Version 710 multiple instances
  of CSQE020E are seen at initial QMGR start and some time after
  restart. At restart this indicates that the QMGR is going
  through all CFSTRUCTS (including those which are 'auto-defined'
  by DEFINE QLOCAL which can specify a CFSTRUCT which does not yet
  physically exist in the CF).
  
  
  
  
  For the case where CFSTRUCTs have been auto-defined by the
  QMGR itself, it is unnecesary for the queue-manager to
  automatically attempt to connect to these structures (either
  at start-up, or when notified by the operating system that
  CF resources have become available). This apar will serve to
  rectify this behavior.

  ****************************************************************
  If a shared queue is defined in a CF Structure that is new but
  not defined in the coupling facility policy, it generates
  messages IXL013I and CSQE020E during queue manager restart after
  a connection to the structure is attempted.
  
  Before the connection to the structure is attempted, the ENF
  listener is started and it is stopped if the connection is
  successful.
  
  When ENF events are received, a connection to the invalid
  structure is attempted generating the IXL013I and CSQE020E
  messages again.
  

Problem conclusion

• Queue manager restart has been changed to not attempt to connect
  to CFSTRUCT objects that had never been used.
  
  This will stop all the IXL013I and CSQE020E messages for this
  structure unless one of the queues defined in the structure is
  opened by an application.
