Enhanced shared memory based communication driver for improved performance and scalability is described. An example method includes creating a shared memory segment for a database server instance. The database server instance and a client reside on a same computing device. A first database connection is established to the database server instance using a pre-configured communication end point. An identifier of the shared memory segment for the database server instance is sent to the database server instance and the database server instance listens to subsequent connection requests generated on the shared memory segment. Moreover, a second database connection to the database server instance is established using the shared memory segment as a communication end point. Upon a successful connection of the second database connection, the first database connection is closed.

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.
