摘要

PURPOSE: To appropriately process an error state by backing out resource updating performed in a working unit in accordance with the detection of the error state by using an application and, at the same time, preventing eliminated operation from being used for another application. CONSTITUTION: A connection manager 90 calls a restoration manager 130 and, when an application outputs a commit or back out or the connection manager 90 recognizes the termination of the application, the manager 90 commits or backs out transactions. The restoration manager 130 calls a restoration log manager 140 and writes a transaction state converting log record. The manager 150 calls a lock manager 150 and cancels all committed locks after recording the terminations of committing or backing out operation on a log.
