2.2.9.1.2.1 CONNTYPE_PARTNERTM_BRANCH

The CONNTYPE_PARTNERTM_BRANCH connection type is used by a subordinate transaction manager to register a new subordinate enlistment with a superior transaction manager. The two transaction managers also use this connection type to execute the Two-Phase Commit protocol. This connection type is initiated as a result of a TXUSER_ASSOCIATE_MTAG_ASSOCIATE message that is sent by an application to the subordinate transaction manager to request a pull propagation operation.
