APAR status
Closed as program error.
Error description
A client application connected to a V8 distributed queue manager using SVRCONN channels configured with SHARECNV>0, can generate FDC files in the client side when the queue manager is shutdown while the application is running. FDC reports error rrcE_PROTOCOL_ERROR, probe Id CO398008 and error message AMQ9504. An FDC with Probe Id XC076010 is also generated.
Local fix
Workaround is to terminate client application prior to shutting down the queue manager
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM MQ client applications that use channels with SHARECNV > 0 may be affected by this problem. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A logic error within the MQ channel code meant that it was possible for a channel process to incorrectly attempt to send a notification to a client, after the conversation or connection to the client had been terminated, while the queue manager was ending. This attempt to communicate over a closed connection resulted in the FDC records being generated.
Problem conclusion
The MQ channel logic has been changed to avoid sending notifications to a client after the channel conversations have been ended. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.12 v9.1 CD 9.1.2 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 ---------------------------------------------------------------
