ABSTRACT:
The system, method and program of this invention provides a technique that enables a client, connected by a network, such as TCP/IP, to a multi-server system, such as a parallel database management system, to locate a server product that may have moved to a different network address within the multi-server system. More specifically, the client is able to perform two-phase commit and automatic resynchronization with a same DBMS server that may have moved to a new network address before a transaction with the client was committed. In order to complete the two-phase resynchronization process for uncompleted units of work, the client system has to reestablish connection to the previously connected DBMS member.
