Error description
The change in behaviour introduced by APAR IV56612 will be withdrawn from the product
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All MQ users using channels for communication. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: APAR IV56612 introduced code changes which check the TRPTYPE of the channel on both communicating sides. For example, both the sender and receiver sides of the channel pair. The channels would not be started if the TRPTYPE on each side did not match. This change was directly in contradiction with the documented behaviour of MQ, which states the following for the TRPTYPE attribute: "This parameter is optional because, if you do not enter a value, the value specified in the SYSTEM.DEF.channel-type definition is used. However, no check is made that the correct transport type has been specified if the channel is initiated from the other end. On z/OS, if the SYSTEM.DEF.channel-type definition does not exist, the default is LU62."
Problem conclusion
The IV56612 code changes have been removed from the product in order to remain consistent with the documented behavior. Accordingly, this check of the TRPTYPE values is no longer performed. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.1 7.1.0.8 v8.0 8.0.0.4 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 ---------------------------------------------------------------
