Application Switchover in a Data Guard configuration

in High Availability Data Guard, Sharding and Global Data Services (MOSC) 7 commentsAnswered

We are running RAC Oracle 19c database on an active physical data guard configuration.

When we switchover the database from primary to standby, we want the applications to automatically reconnect to the new primary database.

Our team doesn't manage the applications that connect to the database. So, our solution can be implemented/modified on the database side.

We are looking at TAF (Transparent Application Failover) and FAN (Fast Application Notification) details.

Other than changing the tnsnames.ora in the client application side, is there any other change that is needed on the client side to implement TAF basic configuration with FAN?

Howdy, Stranger!
