Abstract
A transaction processing system providing improved methodology for invoking two-phase commit protocol (2PC) is described. More particularly, a transaction is handled without use of 2PC until the system determines that the transaction does, in fact, involve changes to more than one database. The methodology improves overall system performance by looking at each transaction to determine whether the transaction actually requires use of 2PC before incurring the overhead associated with use of the two-phase commit protocol. Because only a small percentage of real world transactions result in updates to more than one database, the methodology improves the overall performance of transaction processing systems considerably.
