You are administrating a database that supports an OLTP workload. A few users complain about the poor performance of some SQL statements. You notice that these SQL statements belong to different applications and conclude that there is no correlation between them. You create a SQL Tuning Set (STS) containing these SQL statements.
What must you do to analyze and generate recommendations for the SQL statements in the STS?
- A. Submit the STS as input to the SQL Tuning Advisor to generate recommendations for SQL plan baselines.
- B. Submit the STS as input to the SQL Performance Analyzer to generate recommendations for creating indexes and materialized views.
- C. Submit the STS as input to the SQL Tuning Advisor to generate recommendations for indexes or SQL profiles or both.
- D. Submit the STS as input to the SQL Access Advisor to generate recommendations for SQL profiles.
Correct Answer: A š³ļø
