Error description
v7 C++ applications returned the error 2298 (MQRC_FUNCTION_NOT_SUPPORTED) when all of the following conditions are met: a) The application issues the Get call with MQGMO_CONVERT b) The application uses automatic allocation of memory for the message using automaticBuffer() c) Either the queue manager is V6 or sharing conversations is disabled on a V7 queue manager (SHARECNV on the channel is 0).
Local fix
None, Install fix. C++ application ran fine at v6. The V7 C++ client can return MQRC_FUNCTION_NOT_SUPPORTED. This happenswhen sharing conversations is not enabled and a message is got with MQGMO_CONVERT using a message buffer that is supplied automatically. Sharing conversations is not enabled when communicating with a pre V7 queue managers or when SHARECNV on the CLNTCONN or SVRCONN channel is set to 0.
Problem summary
**************************************************************** USERS AFFECTED: Users of the v7 C++ client applications when MQGMO_CONVERT and automaticBuffer() are used together with sharing of conversations disabled. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: The new code introduced for v7 makes an incorrect validation check when sharing conversations are disabled and hence reported the MQRC_FUNCTION_NOT_SUPPORTED error.
Problem conclusion
The incorrect check during an MQGET call was modified so that the error does not occur. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.0 -------- -------------------- Windows U200306 AIX U823774 HP-UX (PA-RISC) U823665 HP-UX (Itanium) U823667 Solaris (SPARC) U823772 Solaris (x86-64) U824344 iSeries tbc_p700_0_1_0 Linux (x86) U823664 Linux (x86-64) U823773 Linux (zSeries) U823668 Linux (Power) U823666 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 ---------------------------------------------------------------
