Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When event messages are enabled, if the * * system event queue is defined as an * * alias queue to a topic, the put * * processing to the QAlias may fail to * * put the message to the subscribers. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the event message is being put to the event queue, in the case where it is a QAlias which targets a topic, the ASID of the message buffer of the event message is set to the application address space. However the message buffer is actually within the queue managers address space, which may result in the put of the event message failing, with MQRC_BUFFER_ERROR (MQRC 2004).
Problem conclusion
Event message processing has been changed for this scenario, to use the correct ASID for the message buffer, when putting the event message to a topic in this scenario. 000Y CSQMIARC
