First, the application attempts to connect to the primary database server, Database Server A (1). If connection failover is enabled and Database Server A fails to accept the connection, the application attempts to connect to Database Server B (2). If that connection attempt also fails, the application attempts to connect to Database Server C (3).In this scenario, it is probable that at least one connection attempt would succeed, but if no connection attempt succeeds, the driver can retry each alternate database server (primary and alternate) for a specified number of attempts. You can specify the number of attempts that are made through the connection retry feature. You can also specify the number of seconds of delay, if any, between attempts through the connection delay feature. See Using Connection Retry for more information about connection retry.
