Scenario 2: Other software provides the coordination

In scenario 2, an external transaction manager coordinates global units of work, starting and committing them under control of the transaction manager's API. The MQBEGIN, MQCMIT, and MQBACK verbs are unavailable.

This section describes this scenario, including:

• External sync point coordination
• Use CICS
• Use the Microsoft Transaction Server (COM+)

The IBM MQ client for HP Integrity NonStop Server can use the HP NonStop Transaction Management Facility (TMF) to coordinate global units of work. For more information, see Use HP NonStop TMF.

• External sync point coordination
  A global unit of work can also be coordinated by an external X/Open XA-compliant transaction manager. Here the IBM MQ queue manager participates in, but does not coordinate, the unit of work.
• Use CICS
  CICS is one of the elements of TXSeries.
• Use the Microsoft Transaction Server (COM+)
  COM+ ( Microsoft Transaction Server) is designed to help users run business logic applications in a typical middle tier server.
