IC64545: CONVERSION NOT SUPPORTED ERROR (AMQ6047) REPORTED AFTER INSTALL OF WMQ V7.0.1.0

WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.3
WebSphere MQ V7.0 Fix Pack 7.0.1.3

APAR status

• Closed as program error.

Error description

• Error AMQ6047, conversion not supported, reported after
  installing WebSphere MQ (WMQ) v7.0.1.0. In this case, trace
  shows:
  
  (07)--------{  xcsConvertString
  fromCCSID:1051 toCCSID:932, in length:8, out length:8 options:
  00000001
  (07)--------}! xcsConvertString (rc=xecX_E_CONV_NOT_SUP)
  
  In 7.0.1.0, changes were made to ensure that if the remote queue
  manager does not support message properties and the channel has
  PROPCTL set to COMPAT (default setting), then unsupported RFH2
  syntax is removed from the message before sending it across to
  the remote queue manager. Before removing the RFH2 syntax, the
  RFH2 syntax is converted from 1051 to 932 (system locale).
  There is no direct conversion between these two CCSIDss as they
  encode different languages. As a result, the conversion fails
  and the message is not sent across the channel.
  
  This problem does not exist in fix packs released prior to
  7.0.1.0. This problem is only evident from 7.0.1.0 onwards.
  The error xecX_E_CONV_NOT_SUP is reported in prior versions
  in the trace files but the messages are sent.
  

Local fix

• If Message Properties is not used, set channel attribute
  PROPCTL to NONE as a work-around
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of WMQ who send messages via channels to an older
  queue manager which does not support message properties (for
  example a v6.0 queue manager). This problem manifests only if
  there is no direct conversion between the user locale and the
  CCSID of the queue manager (for example 1051 and 932).
  
  Platforms affected:
   All Distributed (iSeries, all Unix and Windows)
  ****************************************************************
  PROBLEM SUMMARY:
  The problem occurred when the channel process tried to parse
  through the message to remove any unsupported MQRFH2 syntax from
  a message as the message was going to be sent down a channel to
  a back level queue manager (for example, a v5.3 queue manager).
  During this stage, there was an attempt to convert some headers
  in the message into the CCSID of the queue manager. However,
  these headers in the message were in CCSIDs that could not be
  converted into the CCSID of the queue manager and vice versa.
  As a result, the conversion failed with "xecX_E_CONV_NOT_SUP"
  error and the message was not sent to the remote queue manager.
  
  A review of the data that was being converted indicates that,
  the respective data was in the invariant character set. This
  kind of invariant data does not require a full conversion table
  for the conversion to take place.
  

Problem conclusion

• The code was modified to correctly handle the data conversion
  to enable the RFH headers to be modified to be shipped to a
  back level system, by performing invariant data conversion
  where appropriate.
