X/Open Distributed Transaction Processing Standard

The X/Open Distributed Transaction Processing (X/Open DTP) group has defined a number of transaction processing standards. The two standards that are most relevant to OLE Transactions are the TX and XA standards.

• The X/Open DTP TX standard defines the application programming interfaces which an application program uses to communicate with the transaction manager. Application programs use these calls to begin, commit, and rollback transactions.
• The X/Open DTP XA standard defines the application programming interfaces which a resource manager uses to communicate with a transaction manager. The XA interfaces enable resource managers to join transactions, to perform two-phase commit, and to recover in-doubt transactions following a failure.
