Document Type and Number:
Japanese Patent JP5905122
Kind Code:
B2
Abstract:
Replication is performed with consideration of data integrity between each subsystem when replication of a computer system that uses data by processing data and transferring the data to a next subsystem is performed. A management device that manages a computer system including a second subsystem which performs a predetermined process for data processed by a first subsystem and generates data which is a target of data processing by a third subsystem obtains process history information in which information indicating an input source and an output destination subsystem of data that is processed by each subsystem is included and trigger information in which information indicating a trigger for data input and output of the input source and the output destination subsystems is included, thereafter detects a dependence relationship of data input and output between each subsystem from the process history information, calculates a replication trigger for subsystems subsequent to a next subsystem for each of the subsystems subsequent to the next subsystem that is next to a subsystem of which an input source is not present with reference to the trigger information, and generates, in response to the replication trigger, a replication of each subsystem in another different computer system.
