Research And Implementation Of Real-time Data Replication System Based On DB2

With the advent of the information age,data security and distribution are a topic of great concern to government departments,enterprises and individuals.Especially when it comes to sensitive data,such as state secrets,internal corporate information,etc.,the security of these data is even more important.If there are no recent backup images,when the disaster or accident causes data damage,it will make a very huge impact.Therefore,data replication synchronization technology is extremely important.IBM's DB2 database is one of the mainstream databases in the market,especially at the enterprise level.Replication technology based on DB2 is very important for enterprises.This paper introduces the basic concepts of the database and the comparison of the advantages and disadvantages of different replication methods based on DB2.During the process of DB2 data replication,data source registration,control table establishment,subscription set design,data grabbing and application are analyzed and summarized,and finally DB2-based real-time replication system is realized.It also analyzes common faults and provides solutions.This system is a data replication based entirely on logs,eliminating the need to install software other than the DB2 database.So,it can be applied in a wide range.In addition to the DB2 database,it also supports data replication between non-DB2 relational databases and DB2.After the final test,the expected goal was achieved.
