Abstract:
Seamless failover in a database replication environment which has a primary database server and a plurality of standby database servers, is described. An example method includes orderly terminating transactions on the primary database server, where the transactions are originated from client applications. The transaction logs of the primary database server are drained and the transaction logs are replicated from the primary database server to the plurality of standby database servers. One of the standby database servers is designated as a new primary database server processing user transactions.
