IT40296: The DISPLAY CHSTATUS command incorrectly provides output for inactive channels

APAR status

• Closed as program error.

Error description

• The DISPLAY CHSTATUS command is explicitly displaying a record
  for an INACTIVE channel.
  
  This happens after the MQSC command 'STOP CHL(chlname)
  STATUS(INACTIVE)' is applied to a sender channel in STOPPED
  state.
  
  The expected behavior is to display the output as 'Channel
  status not found'.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of MQ channels between queue managers.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A logic error within the stop-channel routines meant that the
  channel status entry was not removed if an already stopped
  channel was stopped with INACTIVE state.   This then led the
  DISPLAY CHSTATUS code to explicitly display a channel status
  record, marked as having INACTIVE state.
  

Problem conclusion

• The IBM MQ queue manager channel logic has been corrected to
  remove the channel status entry from the table when the already
  stopped channel is stopped with INACTIVE state.
