The invention provides transaction synchronization in the form of COMMIT processing in a distributed, heterogeneous database system wherein some resources are synchronized to a transaction by a single-phase commit procedures while other resources synchronize by multi-phase commit procedures. The invention invests an application requestor at an application site with authority to represent all single-phase commit resources in multi-phase commit processing.

Method for synchronizing transaction processing in a distributed

Application programs which are developed and scheduled within a first computing system environment are permitted to access relational data registered at a remote database management system (DBMS) operating in a second computing environment dissimilar to the first computing environment. Access to data through the DBMS from an application execution site remote from the DBMS is supported by a process, logically subordinate to the application program which maps application program data access requests to the DBMS.
