Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1. * **************************************************************** * PROBLEM DESCRIPTION: Putting an event message to a remote * * queue, with intra-group queuing enabled * * may result in a 0C4 abend in CSQMPOM. * * This results in the intra-group queuing * * agent to go into a retry state. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the intra-group queuing agent attempts to put an event message to a remote queue it puts the message into a 64-bit buffer. It then calls CSQMPOM to put the message to the destination event queue, this does not expect the buffer to be in 64-bit storage, resulting in only the lower 4 bytes of the address to be used, and an 0C4 abend in CSQMPOM. As the message was not successfully put, the IGQ agent goes into a retry state.
Problem conclusion
Temporary fix
Comments
CSQMPOM has been updated to correctly handle event messages with the message data buffer in 64-bit storage.
