Connection retry defines the number of times that the data provider attempts to connect to the primary, and, if configured, alternate database servers after the first unsuccessful connection attempt. Connection retry can be an important strategy for system recovery. For example, suppose you have a power failure scenario in which both the client and the server fail. When the power is restored and all computers are restarted, the client may be ready to attempt a connection before the server has completed its startup routines. If connection retry is enabled, the client application can continue to retry the connection until a connection is successfully accepted by the server.
Connection retry can be used in environments that only have one server or can be used as a complementary feature in connection failover in environments with multiple servers.
