The CONNTYPE enumeration defines the connection types that are used by MSDTC Connection Manager: OleTx Multiplexing Protocol Specification [MS-CMP].

CONNTYPE_TXUSER_BEGINNER:  This connection type is used by applications that begin, commit, and roll back transactions.

CONNTYPE_TXUSER_IMPORT:  This connection type is used by a destination application to complete a Push Propagation that is initiated by a source application.

CONNTYPE_TXUSER_ENLISTMENT:  This connection type is used by a durable resource manager to establish an enlistment with its transaction manager.

CONNTYPE_TXUSER_EXPORT:  This connection type is used by a source application to initiate a push propagation to a destination application.

CONNTYPE_TXUSER_RESOURCEMANAGER:  This connection type is used by a durable resource manager to register with its transaction manager.

CONNTYPE_TXUSER_REENLIST:  This connection type is used by a durable resource manager to determine the outcome of an In Doubt transaction.

CONNTYPE_TXUSER_RESOLVE:  This connection type is used by an application either to manually resolve the outcome of an In Doubt transaction or to cause its transaction manager to forget a transaction that is in the Failed to Notify state.

CONNTYPE_TXUSER_VOTER:  This connection type is used by a volatile resource manager to establish a voter enlistment with its transaction manager.

CONNTYPE_TXUSER_ASSOCIATE:  This connection type is used by a destination application to complete the pull propagation of a transaction from a source application.

CONNTYPE_TXUSER_GETTXDETAILS:  This connection type is used by an application to retrieve details about a transaction from its transaction manager.

CONNTYPE_TXUSER_PHASE0:  This connection type is used by a resource manager to enlist for Phase Zero notifications from its transaction manager.

CONNTYPE_TXUSER_BEGIN2:  This connection type is used by an application to begin, commit, or roll back a transaction or to change the time-out of a transaction. This connection type supersedes CONNTYPE_TXUSER_BEGINNER and CONNTYPE_TXUSER_SETTXTIMEOUT2.

CONNTYPE_TXUSER_IMPORT2:  This connection type is used by a destination application to complete a Push Propagation that is initiated by a source application. This connection type supersedes CONNTYPE_TXUSER_IMPORT.

CONNTYPE_TXUSER_GETSECURITYFLAGS:  This connection type is used by an application to obtain the security configuration of its transaction manager.

CONNTYPE_TXUSER_TRACE:  This connection type is used by an application to ask its transaction manager to trace the status of a transaction by using an implementation-specific mechanism.

CONNTYPE_TXUSER_SETTXTIMEOUT:  This connection type is used by an application to modify the time-out of a transaction.

CONNTYPE_TXUSER_SETTXTIMEOUT2:  This connection type is used by an application to query the transaction manager's support for modifying the time-out of a transaction.

CONNTYPE_TXUSER_PROMOTE:  This connection type is used by an application to:

• Begin a transaction using an application-specified transaction identity

• Commit or rollback a transaction

• Change the time-out of a transaction

  This connection type supersedes CONNTYPE_TXUSER_SETTXTIMEOUT2.

CONNTYPE_TXUSER_EXTENDEDWHEREABOUTS:  This connection type is used by an application to obtain Extended Whereabouts from its transaction manager.

CONNTYPE_TXUSER_RESOURCEMANAGERINTERNAL:  This connection type is used by a durable resource manager to register with a transaction manager and to detect duplicate registrations. This connection type supersedes CONNTYPE_TXUSER_RESOURCEMANAGER.

CONNTYPE_TXUSER_EXPORT2:  This connection type is used by a source application to initiate a push propagation to a destination application. This connection type supersedes CONNTYPE_TXUSER_EXPORT.

CONNTYPE_PARTNERTM_PROPAGATE:  This connection type is used by a superior transaction manager to do a push propagation of a transaction to its subordinate transaction manager and to execute the Two-Phase Commit Protocol.

CONNTYPE_PARTNERTM_REDELIVERCOMMIT:  This connection type is used by a superior transaction manager to redeliver a Commit notification for a transaction to its subordinate transaction manager.

CONNTYPE_PARTNERTM_CHECKABORT:  This connection type is used by a subordinate transaction manager to query the outcome of a transaction from its superior transaction manager.

CONNTYPE_PARTNERTM_BRANCH:  A subordinate transaction manager uses this connection type to register a new subordinate enlistment with a superior transaction manager.
