Gateway process overview

The HP NonStop Transaction Management Facility (TMF) provides services to enable a gateway process to register as a resource manager. The TMF/Gateway process used by IBM MQ client for HP Integrity NonStop Server runs under Pathway.

IBM MQ client for HP Integrity NonStop Server registers a single gateway process for each queue manager that is coordinated by TMF, therefore we must configure a separate TMF/Gateway for each queue manager that is to participate in TMF coordinated units of work. This registration is so that each queue manager is an independent resource manager, and for administrative purposes, registering each queue manager once with HP NonStop TMF results in an easy to understand mapping.

For multiple installations of IBM MQ client for HP Integrity NonStop Server, we must nominate a single gateway process from one of these installations for each queue manager to be coordinated by TMF.

The interface to the gateway process supports any client at the same version or earlier.
