Method for transaction recovery in three-tier applications

摘要

A three-tiered transaction processing system is provided in which state information maintained in the database tier is used to facilitate recovery of transaction coordinators without the transaction coordinators having to maintain their own recovery information and a method of accessing such state information while controlling the lifetime of this recovery information; i.e., keeping it around long enough so that client tier will have a consistent view of the world before the information is forgotten. This solves the problem of outcome determination.
