IT25614: MQ 9.0: AMQ8227 Channel not found error when issuing command to stop auto-defined CLUSSDR channel

APAR status

• Closed as program error.

Error description

• When using MQ 9.0 and issuing runmqsc command "stop channel"
  for an auto-defined clussdr channel, the following error is
  generated:
  AMQ8227 channel not found
  
  The runmqsc commmand "DISPLAY CHS" (to display channel status)
  shows that the clussdr channel is in running state.
  
  The problem happens when the environment variable is set while
  creating queue manager:
    MQSNOAUT=YES
  
  Because of this environment variable, the Authorization Service
  stanza is not created inside the file qm.ini.
  

Local fix

• Recreate the queue manger without setting the environment
  variable:
    MQSNOAUT=YES
  If you have already created the environment variable, unset it:
  Windows:  set MQSNOAUT=
  Unix:     unset MQSNOAUT
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users that have created a queue manager with no authorization
  service by setting MQSNOAUT=YES before running crtmqm and
  configures the queue manager to be a member of a Queue Manager
  Cluster
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The problem occured because authorisation checking returned a
  success return code when no authorization service is available.
  Some cluster object lookup code relies on an
  MQRC_UNKNOWN_OBJECT_NAME return code  to be returned for local
  object checks, before it proceeds to look up the object (in this
  case a channel) in the cluster cache.
  

Problem conclusion

• The problem is fixed by enabling an error to be returned during
  the authorization check in the code (which would typically
  return success when no authorization service is available) and
  handling the error code to perform checks and processing that
  would otherwise not be executed.
