PM72557: WEBPSHERE MQ V7.1.0 RECEIVER CHANNEL EVENTS NOT CREATED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Despite the CHLEV(ENABLED)  set in the Qmgr EVENTs when :
  - a receiver channel ends normally :
  msg CSQX501I CSQ1 CSQXRESP Channel YYY.TO.ZZZ no longer active
  or
  - a receiver channel ends abruptly (msg CSQX208E)
  events messages are not generated in SYSTEM.ADMIN.CHANNEL.EVENT
  .
  Events msgs are not generated because
  rrxResponder is issuing an MQDISC, and setting pWork->hQm to
  MQHC_UNUSABLE_HCONN, before rriEvent is invoked by rriFreeSess
  to issue
  the event message. rriEvent detects that pWork->hQm is set to
  MQHC_UNUSABLE_HCONN and therefore does not issue an event
  message.

  ****************************************************************
  CHLEV(ENABLED) has been set so channel events are generated,
  but when a Receiver channel stops an event message is not
  generated.
  In CSQXRMRS a MQDISC is issued followed by a rriFreeSess to
  tidy up the connection, and one of the actions rriFreeSess
  does is to issue rriEvent to generate the event message.
  But the connection handle has been set to MQHC_UNUSABLE_HCONN
  after the MQDISC which will stop an event message being
  generated.
  

Problem conclusion

• CSQXRMRS has been altered to issue the rriFreeSess before the
  MQDISC.
