IMPLEMENTASI FAILOVER DATABASE MENGGUNAKAN HEARTBEATS

Abstrak

For implement this high availability server, you can use special application software for clustering, such as heartbeat. This heartbeat is part of linux high availability project. Using heartbeat, you can do failover by promoting an active server to serve requests from clients and replace the function of the main server. This is done to ensure that the availability of existing data on the database server is always available when there is a request by the client. The purpose of this research is to build a database server that is always available by implementing a failover server and implementing data replication system on the database server. Database failover technology using heartbeats and using master to master replication system, data availability and system performance increase because the data has a backup. Failover database using heartbeats using master to master replication system has advantages (can do data backup automatically) and disadvantages (requires additional devices), so using this technology needs to be adjusted to the needs of system development.
