  • System and method for supporting XA 2-phase commit protocols with a loosely coupled clustered database server
    Publication number: 20050144299
    Abstract: Indoubt transaction entries are recorded for each member of a database cluster, thereby avoiding the CPU cost and elapsed-time impact of persisting this information to a disk (either via a log write or a relational table I/O). This implementation allows for full read/write access and data coherency for concurrent access by all the members in the database cluster. At any given point in time, a full list of indoubt transactions is maintained for the entire database cluster in a relational table (e.g., an SQL table).
