Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Invalid data added to publication * * messages when written to the dead * * letter queue following a failure to * * deliver to a subscriber. * **************************************************************** * RECOMMENDATION: * **************************************************************** When publishing a message, an attempt was made to deliver the publication message to a remote queue, however the message could not be put to the associated transmission queue and was put to the dead letter queue instead. During the attempt to put to the transmission queue, a transmission queue header (XQH) was added to the message, and during the subsequent put to the dead letter queue, this header was incorrectly included in the message. By this time the storage that previously contained the XQH had been reused, resulting in 428 bytes of invalid data being prepended to the message on the dead letter queue.
Problem conclusion
CSQMDLQP is changed to omit the XQH segment when putting the failed publication message to the dead letter queue. 100Y CSQMDLQP
