Error description
Using a Server-Requester channel to send a message from one WebSphere MQ v7 queue manager to another v7 queue manager fails with the following error: AMQ6047: Conversion not supported. Explanation: WebSphere MQ is unable to convert string data tagged in CCSID 819 to data in CCSID 932. These are supported CCSID's according to the WebSphere MQ v7 Application Programming Reference Manual. The following FDC's are generated: Probe Id :- JD514000 Component :- DmQueueManager.onError Process Name :- D:\IBM\MQ\java\jre\bin\javaw.exe UserApp :- TRUE Major Errorcode :- MQRCCF_CCSID_ERROR . Probe Id :- XC006001 Component :- xcsFreeMemFn Process Name :- D:\IBM\MQ\java\jre\bin\javaw.exe UserApp :- TRUE Major Errorcode :- xecS_I_PRIVATE_MEMORY_ERROR Probe Description :- AMQ6091 Arith1 :- 655711848 27155e68 Comment1 :- invalid tail tag . Probe Id :- ZT372000 Component :- zrfPrepareMsgForBackLevel Process Name :- D:\IBM\MQ\bin\amqrmppa.exe UserApp :- FALSE Major Errorcode :- xecX_E_CONV_NOT_SUP Probe Type :- MSGAMQ6047 The third FDC, ZT372000 / zrfPrepareMsgForBackLevel, shows that WebSphere MQ is trying to prepare a message for sending to a pre-v7 queue manager. In this case however, both queue managers are v7. Additional keywords: CCSID codepage conversion
Local fix
Use a SENDER-REVEIVER channel to ensure the WMQ v7-v7 communication is as efficient as possible.
Problem summary
**************************************************************** USERS AFFECTED: All users of Server-Requester channels talking from a V7.0.* queue manager to another V7.0.* queue manager. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: During the initial negotiation of a channel, parameters are agreed by both ends on what attributes the channel will have. When the channel which initiated the connection did not also initiate the negotiation phase (which is the case in a server to receiver setup) then a particular attribute was not being set correctly. This attribute controls whether the channel supports the new V7 message properties, and because it did not get set then when the message tried to flow it is incorrectly converted into a format understandable by pre-MQ v7.0 releases. In the normal case, for example sender to receiver, then the initiator of the channel also initiates the negotiation and this problem does not occur.
Problem conclusion
WebSphere MQ has been modified to correctly negotiate the attribute in question, meaning a v7 server to v7 receiver setup no longer converts into pre-v7 format when transferring a message. Note this change also prevents the need for conversion to occur, however the conversion error itself is addressed under APAR IC64545. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.4 -------- -------------------- Windows U200323 AIX U835793 HP-UX (PA-RISC) U836458 HP-UX (Itanium) U836463 Solaris (SPARC) U836459 Solaris (x86-64) U836465 iSeries tbc_p700_0_1_4 Linux (x86) U836460 Linux (x86-64) U836464 Linux (zSeries) U836461 Linux (Power) U836462 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 ---------------------------------------------------------------
