Troubleshooting IBM MQ client for HP Integrity NonStop Server

Provides information to help you to detect and deal with problems when you are using the IBM MQ client for HP Integrity NonStop Server.

Toggling between the use of IBM MQ and TMF transactions on a single connection

If an IBM MQ client for HP Integrity NonStop Server toggles between the use of IBM MQ and TMF transactions on a single connection, then IBM MQ operations such as MQPUT and MQGET might fail with a return code of 2072 (0818) (RC2072): MQRC_SYNCPOINT_NOT_AVAILABLE. Errors and a first failure symptom report for the client application are generated in the IBM MQ client for HP Integrity NonStop Server errors directory.

This error occurs because mixed TMF and IBM MQ transactions on a single connection are not supported.

Use the standard facilities that are supplied with the system to record the problem identifier and to save any generated output files. Use either the IBM MQ Support site: IBM MQ Support, or the IBM Support Assistant (ISA): IBM Support Assistant web page to check whether a solution is already available. If we are unable to find a solution, contact the IBM support center. Do not discard these files until the problem is resolved.
