Explanation
| Question ID 20777 | 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?
|
| Option 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.
|
| Option B | Run the Automatic Workload Repository Monitor (ADDM).
|
| Option 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.
|
| Option 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 * SQL Access Advisor is primarily responsible for making schema modification recommendations, such as adding or dropping indexes and materialized views. SQL Tuning Advisor makes other types of recommendations, such as creating SQL profiles and restructuring SQL statements. * The query optimizer can also help you tune SQL statements. By using SQL Tuning Advisor and SQL Access Advisor, you can invoke the query optimizer in advisory mode to examine a SQL statement or set of statements and determine how to improve their efficiency. SQL Tuning Advisor and SQL Access Advisor can make various recommendations, such as creating SQL profiles, restructuring SQL statements, creating additional indexes or materialized views, and refreshing optimizer statistics.

This cache contains the shared SQL and PL/SQL areas and control structures such as locks and library cache handles. Reference: Tuning SQL Statements
