XA Support

The XA interface is part of the X/Open DTP (Distributed

Transaction Processing) standard. It deﬁnes the interface that

transaction managers (TM) and resource managers (RM) use

to perform the two-phase commit protocol. (Resource managers

are underlying database systems such as ORACLE RDBMS,

Microsoft SQL Server, and others.) This interface is not used by

the application programs; it is only used by TM-to-RM exchanges

to coordinate a transaction.

For details on using XA, see the RTR C Application

Programmer’s Reference Manual and the RTR Application

Design Guide.
