You run the SQL Tuning Advisor (STA) to tune a SQL statement that is part of a fixed SQL plan baseline. The STA generates a SQL profile for the SQL statement, which recommends that you accept the profile. Which statement is true when you accept the suggested SQL profile?
Correct Answer: C
Explanation/Reference: Explanation: 15.4 Using Fixed SQL Plan Baselines When you tune a SQL statement with a fixed SQL plan baseline using SQL Tuning Advisor, a SQL profile recommendation has special meaning. When the SQL profile is accepted, the database adds the tuned plan to the fixed SQL plan baseline as a non-fixed plan. However, as described above, the optimizer does not use the tuned plan when a reproducible fixed plan is present. Therefore, the benefit of SQL tuning may not be realized. To enable the use of the tuned plan, manually alter the tuned plan to a fixed plan by setting its FIXED attribute to YES.
