You notice some performance degradation for a high-load SQL statement in your database. After investigations, you run the SQL Tuning Advisor, which recommends a SQL Profile. You accept the profile recommendation resulting in a new, tuned execution plan for the statement.
Your database uses SQL plan management and a SQL plan baseline exists for this SQL statement.
Which statement is true?
A. The database adds the tuned plan to the SQL plan baseline as a nonfixed plan.
B. The database adds the tuned plan to the SQL plan baseline as a fixed plan.
C. The optimizer uses the new tuned plan only when a reproducible fixed plan is present.
D. The created SQL profile will continuously adapt to all changes made to the database, the object, and to the system statistics over an extended length of time.
You are administering a database supporting a DDS workload in which some tables are updated frequently but not queried often. You have SQL plan baseline for these tables and you do not want the automatic maintenance task to gather statistics for these tables regularly.
Which task would you perform to achieve this?
A. Set the INCREMENTAL statistic preference FALSE for these tables.
B. Set the STALE_PERCENT static preference to a higher value for these tables.
C. Set the GRANULARITY statistic preference to AUTO for these tables.
D. Set the PUBLISH statistic preference to TRUE for these tables.
