Oracle Database 12c: Installation and Administration — Question 236

Your database supports a DSS workload that involves the execution of complex queries: Currently, the library cache contains the ideal workload for analysis. You want to analyze some of the queries for an application that are cached in the library cache.
What must you do to receive recommendations about the efficient use of indexes and materialized views to improve query performance?

Answer options

• A. Create a SQL Tuning Set (STS) that contains the queries cached in the library cache and run the SQL Tuning Advisor (STA) on the workload captured in the STS.
• B. Run the Automatic Workload Repository Monitor (ADDM).
• C. Create an STS that contains the queries cached in the library cache and run the SQL Performance Analyzer (SPA) on the workload captured in the STS.
• D. Create an STS that contains the queries cached in the library cache and run the SQL Access Advisor on the workload captured in the STS.

Correct answer: D

Explanation

The correct answer is D because the SQL Access Advisor specifically provides recommendations for indexes and materialized views based on the workload captured in the STS. Options A and C involve tools that focus on query tuning and performance analysis rather than index and materialized view recommendations, while option B is a broader monitoring tool and does not provide specific advice on improving query performance.
