APAR status
Closed as program error.
Error description
MQ C and unmanaged .NET clients earlier at versions earlier than 9.1.3 are sensitive to the incrementing of a version field within the CCDT. If these clients read such a CCDT from a 9.1.3 queue manager, the client is unable to correctly parse the CCDT.
Local fix
Recreate the CCDT file at the same release as the client from MQSC definitions.
Problem summary
**************************************************************** USERS AFFECTED: Users that have clients that use CCDTs generated by newer levels of code are potentially affected. This issue affects the MQ C client and unmanaged .NET client. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A CCDT was generated on an MQ 9.1.3 installation and used by an older level of client, the MQCD version used by MQ 9.1.3 was not understood correctly by the client and the channel definition was corrupted/unusable.
Problem conclusion
The MQ client logic was corrected to permit any version of MQCD to be read and to copy only the fields that the level of client can use. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.14 v9.0 LTS 9.0.0.9 v9.1 CD 9.1.5 v9.1 LTS 9.1.0.5 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
