IT19827: MQ Appliance auto defined CLUSSDR channel fails with AMQ6174 when looking for channel exit

APAR status

• Closed as program error.

Error description

• The auto defined channel used for communicating with a queue
  manager in a cluster fails with the following error message:
  
    AMQ6174: The dynamically loadable shared library
    '/var/mqm/exits64/xxxxxxxx' was not found. The
    system returned error number '2' and error message
    'No such file or directory'.
  
  Since exits are not supported on the IBM MQ Appliance
  queue manager, this generates an error and stops the channel
  from working.  The reference to the exit cannot be removed
  because it is used by other auto defined cluster sender channels
   on other non-Appliance queue managers.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  IBM MQ Appliance users using queue manager clusters which have
  channel exits defined on the cluster receiver channels of non
  Appliance queue managers that are part of the cluster.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  If channel exits are configured for cluster receiver channels
  then the corresponding auto defined cluster sender channels
  created on MQ Appliance queue managers will fail to start since
  exits are not supported on the IBM MQ Appliance.
  

Problem conclusion

• The IBM MQ Appliance code has been modified to ignore channel
  exits on auto defined cluster sender channels.
