PM86921: WMQ 710 - CHANNEL EVENTS ARE NOT GENERATED WHEN WARN=YES IS SPECIFIED IN CHLAUTH RECORDS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• No channel blocked event message with reason
  MQRC_CHANNEL_BLOCKED_WARNING is generated when WARN=YES
  is specified in CHLAUTH records.
  .
  To reproduce the problem, define only one CHLAUTH rule like this
  
  .
  SET CHLAUTH(SYSTEM.ADMIN.SVRCONN) TYPE(ADDRESSMAP) ADDRESS(*)
  USERSRC(NOACCESS) WARN(YES)
  .
  With that rule no channel blocked event message with reason code
  MQRC_CHANNEL_BLOCKED_WARNING is generated.
  
  Changing it from WARN(YES) to WARN(NO) results in a channel
  blocked event message being generated with reason
  MQRC_CHANNEL_BLOCKED.

  * PROBLEM DESCRIPTION: No channel blocked event message is     *
  *                      generated when WARN=YES is specified in *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The following CHLAUTH rule is defined:
  SET CHLAUTH(SYSTEM.ADMIN.SVRCONN) TYPE(ADDRESSMAP) ADDRESS(*)
  USERSRC(NOACCESS) WARN(YES)
  which should generate an event message with return code 2578
  (MQRC_CHANNEL_BLOCKED_WARNING) in the SYSTEM.ADMIN.CHANNEL When
  a connection is made that is covered by this rule, it is allowed
  and no EVENT message is written to SYSTEM.ADMIN.CHANNEL.EVENT.
  The same definition with WARN(NO) will fail and a message will
  be written to SYSTEM.ADMIN.CHANNEL.EVENT with RC 2577
  (MQRC_CHANNEL_BLOCKED).
  

Problem conclusion

• Function rsxMapChannelToUserId in CSQXRSCM has been updated to
  honour WARN(YES) on an ADDRESSMAP rule.
