IT11547: WEBSPHERE MQ CLIENT APPLICATIONS CANNOT USE CCDT FILES GENERATED ON A NEWER LEVEL QUEUE MANAGER.

APAR status

• Closed as program error.

Error description

• An IBM MQ v8 Queue Manager is used to generate a CCDT file,
  which is then shared with a  v7.1 WebSphere MQ Client.
  
  The application using the v7.1 WebSphere MQ Client is unable
  to connect to the queue manager using this CCDT file.
  

Local fix

• Generate the CCDT on a queue manager major version (version and
  release) which is less than or equal to the version of the IBM
  MQ Client
  code.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of pre-v8 clients who use CCDT files generated on a v8
  queue manager
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  IBM support for using CCDT files on older client levels is
  documented at this link:
  
  http://www-01.ibm.com/support/docview.wss?uid=swg21312967
  
  The compatibility restrictions were such that a newer CCDT
  cannot be used on an older client
  even if the older client was not making use of the attributes
  that were added in the newer version
  of the product.
  

Problem conclusion

• This APAR change relaxes the restriction by allowing newer CCDTs
  to be used on older clients but
  with the caveat that the older client cannot make use of any of
  the newer channel attributes.
  
  These attributes will assume their default values when the CCDT
  is negotiated with the queue manager.
