Oracle WebLogic Server 12c: Administration I — Question 11

GridLink data sources are designed for use with an Oracle RAC database. By using the Fast Connection Failover (FCF) pattern, GridLink data sources can quickly react when a RAC node goes down.
Which two statements are true? (Choose two.)

Answer options

• A. The Oracle Notification Service is used to notify the data source of changes to RAC nodes.
• B. The reaction is quick, because in using FCF all network timeouts are set very low.
• C. FCF is faster because it polls and tests connection, freeing the data source from these tasks.
• D. FCF requires the use and configuration of a database server in the GridLink data source.
• E. You can use any Oracle Thin database driver with a GridLink data source.

Correct answer: A, D

Explanation

Option A is correct as the Oracle Notification Service plays a crucial role in alerting the data source regarding changes in RAC nodes. Option D is also correct since configuring a database server is essential for the GridLink data source to function properly. Options B, C, and E are incorrect because they misrepresent the functionality and requirements of FCF and GridLink data sources.
