摘要

PPROBLEM TO BE SOLVED: To provide a failure restoring method of distributed transaction for continuing commitment processing by an alternative means when a failure occurs during the commitment processing. PSOLUTION: An existence management means 362 detects when a server processing means 32 is down during the commitment processing of transaction. A transaction restoring means 35 takes over the transaction which is processed by the server processing means 32 by referring to a transaction information management table 341 and a resource information management table 342. A two-phase commitment TX control means 372 continues the commitment processing with respect to the update of data on a database file 38 from a data update state in transaction information. When the commitment processing is completed, the completion is notified to the two-phase commitment TX control means 271 and the data update state on the transaction information management table 241 is rewritten.
