Database support for coordinated message flows

If the message flow processing includes interaction with an external database, the transaction can be coordinated using XA technology.

This ensures that all participants update or return to a consistent state. This external coordination support is provided by the underlying WebSphere MQ facilities on distributed systems, and by Resource Recovery Services (RRS) on z/OS.

The following databases provide the correct level of XA support for coordinating message flows on distributed systems:

On z/OS, database support for coordinated message flows is provided by DB2 only.
