Error description
When using the GMO_CONVERT option, an application receives a message larger than the original buffer length. The message body has been converted, but the MQMD.CodedCharSetId reports the original CCSID before the message was converted. The application is using asynchronous consume directly, or is a Java/JMS application.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When performing async consume with * * convert the staging area may be * * resized. When this happens, the MQMD * * may be overwritten, causing the message * * to return a converted body with the * * MQMD of the unconverted message. * **************************************************************** A logic error when handling conversion of large messages within the MQ channel process meant that the MQMD prior to data conversion could be written into the returned data instead of the MQMD after conversion. As such the CCSID and encoding fields did not correctly reflect the converted data being returned.
Problem conclusion
The MQ conversion logic has been corrected to return the MQMD fields reflecting the data after conversion.
