Error description
The subscriber app called MQGET with MQGMO_CONVERT. The message contained headers with (header).CodedCharSetId = MQCCSI_INHERIT. The MQGET call incorrectly returned the unconverted message to the application with warning completion and reason codes (CompCode = MQCC_WARNING, Reason = MQRC_SOURCE_CCSID_ERROR). The correct behaviour is to convert the message. Also failure data capture (FDC) records might be written with details matching these: - VP028002 vwb_rf_header vrcE_BAD_CCSID_0 - VP029002 vwb_rf_header_2 vrcE_BAD_CCSID_0
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Publish/subscribe applications where the message contains headers that use MQCCSI_INHERIT. The problem does not affect point-to-point queued MQPUTs/MQGETs. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: The published message contained at least one MQ header in which the (header).CodedCharSetId was MQCCSI_INHERIT. MQCCSI_INHERIT has the value -2, and is not a real coded char set identifier. Instead it is an instruction to the queue manager that it should replace the (header).CodedCharSetId with the value from the preceding header. The MQ code was not successfully changing the value to the correct coded char set identifier (CCSID), but was leaving the value of -2 in that position. The subscriber called MQGET with MQGMO_CONVERT. Because the MQ code had not changed the value from -2 to a real valid CCSID, the MQGET returned the unconverted message to the application with warning completion and reason codes (CompCode = MQCC_WARNING, Reason = MQRC_SOURCE_CCSID_ERROR).
Problem conclusion
The MQ code has been corrected to ensure that the occurrences of MQCCSI_INHERIT are replaced with the correct CCSID, so avoiding the problem reported. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.9 v8.0 8.0.0.9 v9.0 CD 9.0.5 v9.0 LTS 9.0.0.4 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 ---------------------------------------------------------------
