Title:
SERVER SYSTEM AND REPLICATION METHOD
Document Type and Number:
Japanese Patent JP2018136775
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To quickly ensure the redundancy of important data while reducing the impact on service provision when collective replication is performed.SOLUTION: ACT-based DB server 10A of DB server system 100 performs control in such a manner that data having been set as data of high importance, among data stored in DB 15A of the ACT-based DB server 10A, is preferentially processed in replication from ACT-based DB server 10A to SBY-based DB server 10B compared to data having been set as data of low importance. Then, when the processing load of the ACT-based DB server 10A exceeds a threshold 2 during the replication for the data of low importance, the ACT-based DB server 10A suspends the replication.SELECTED DRAWING: Figure 1
