Patent ID: 8572047

Claim:
An integrated management database system having a plurality of element databases for holding configuration information about an information system to be managed and an integrated database for integrally managing the plurality of element databases, wherein the integrated database comprises: a storage device including a non-transitory computer readable storage medium to store the integrated database; a configuration information database to collectively manage the configuration information held in the plurality of element databases; processing policy registration unit for registering in advance a processing policy for a two-phase commit protocol for each of the configuration information registered in the configuration information database; update request unit for referring to the processing policy relating to update data registered in the processing policy registration unit when data stored in the configuration information database is updated, and transmitting an update request only to a higher priority element database holding the update data; updatability decision unit for receiving a response from the element database to which the update request unit transmitted the update request, and determining whether or not an update is committed based on the received response; and update process communication unit for instructing all element databases holding the update data to perform commit or rollback depending on the determination result of the updatability decision unit, wherein the processing policy is information for classification of the element database and configuration information database of the integrated database into a priority element database, a reference element database, or an other element database, according to priority of the update data held by each of the element databases, the processing policy including a condition of determining a priority element database or a reference element database based on a mathematical expression for calculating a priority and on a calculated priority, wherein the mathematical expression includes as coefficients a point assigned to each of the element databases, a point assigned to the configuration information database of the integrated database, and a point assigned to a master element database holding the configuration information as a primary information source in the system, and wherein the update request unit determines each element database as a priority element database, a reference element database or an other element database, and notifies only the priority element database and the reference element database of the update request.
