Method and system for data update synchronization by two-phase commit

摘要

In an integrated management database system having a plurality of element databases holding the configuration information about an information system and an integrated database for integrally managing the element databases, an element database which cannot return a reply while maintaining a secure state in response to an update request is not informed of the update request in the first phase of a two-phase commit, thereby attaining synchronization when data is updated, and maintaining the consistency of the data in the system.
