IT21093: Administered subscription with DESTCLAS(PROVIDED) cannot be joined by MQ Light clients.

APAR status

• Closed as program error.

Error description

• There are cases where it is useful for an administrator to
  create an MQ Light subscription manually (following the MQ Light
  sub naming conventions of ':private:<clientid>:<topicstring>' or
  ':share:<sharename>:<topicstring>').
  
  This works currently if the DESTCLAS of the administered
  subscription is MANAGED, because MQ Light clients use managed
  subscriptions themselves. However if the administered sub is
  DESTCLAS(PROVIDED), the MQ Light client tries to modify it to
  DESTCLAS(MANAGED) which fails. Error that may be encountered is
  MQRC_DEST_CLASS_NOT_ALTERABLE
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of:
  
  - The WebSphere MQ V8 AMQP channel
  - The IBM MQ V9 AMQP channel
  
  who have a MQ Light client applications that:
  
  - subscribes to an administered Subscription with PROVIDED
  destination (queue).
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  Administered subscription of a MQ Light client failed when it
  was DESTCLASS(PROVIDED) with the following exception:
  
  	MQException: AMQXR0004E: MQSeries verb=SPISubscribe(String)
  returned cc=2(int) MQCC_FAILED rc=2533(int)
  MQRC_DEST_CLASS_NOT_ALTERABLE
  
  because the MQ Light client tried to modify the administered
  subscription to DESTCLAS(MANAGED). This caused a problem because
  MQ Light clients can use only managed subscriptions.
  

Problem conclusion

• The AMQP listener has been updated to let the MQ Light clients
  join an existing administered subscription without modifying the
  DESTCLAS.
