• Test the failover functionality in the service
• Relocate a service from one instance to another
• Collect and view statistics on the sessions connected to a service grouped by module and action.

In this lecture, you will learn how to perform the following:

• Set up the following configurations:

•  Basic TAF on server side
•  Preconnect TAF on the client side and on the server side.
• Describe Fast Connection Failover (FCF)
• Describe and enable Fast Application Notification (FAN)

this is to continue the previous lecture.

In this practice you will implement and test different high availability methods for client connections in Oracle RAC database. Specifically, you will perform the following:

• Configure client-side connect-time load balancing
• Configure server-side connect-time load balancing with and without having the Load Balancing Advisory (LBA) enabled
