Control-M/Server for UNIX and Microsoft Windows and Control-M/Enterprise Manager cannot use Transparent Application Failover (TAF) or Fast Application Notice (FAN)
Oracle Transparent Application Failover (TAF) and Fast Application Notice (FAN) are features of the Java Database Connectivity (JDBC) Oracle Call Interface (OCI) driver. They enable the application to automatically reconnect to a database, if the database instance to which the connection is made fails. In this case, the active transactions roll back.
When an instance to which a connection is established fails or is shutdown, the connection on the client side becomes stale and would throw exceptions to the caller trying to use it. TAF enables the application to transparently reconnect to a preconfigured secondary instance creating a fresh connection, but identical to the connection that was established on the first original instance. That is, the connection properties are the same as that of the earlier connection. This is true regardless of how the connection was lost.
There are High Availability features included with Control-M/Server for UNIX and Microsoft Windows 9.0.00 onwards that can be used instead.
There is also the option of using other database features to provide High Availability such as Oracle Data Guard or Microsoft SQL Server Always On.To manually reconfigure Control-M/Enterprise Manager or Control-M/Server to point to DR, run the command “restore_host_config -reconf_db” to get the usage utility, and use the options necessary for your environment. More details are found in the Utilities Guide documents how to run "restore_host_config" in HA environment and other procedure to ensure the changes take effect.
