Which three functions are performed by the SQL Tuning Advisor?
A.
Building and implementing SQL profiles
B.
Recommending the optimization of materialized views
C.
Checking query objects for missing and stale statistics
D.
Recommending bitmap, function-based, and B-tree indexes
E.
Recommending the restructuring of SQL queries that are using bad plans
Explanation:
The SQL Tuning Advisor takes one or more SQL statements as an input and invokes the Automatic Tuning
Optimizer to perform SQL tuning on the statements. The output of the SQL Tuning Advisor is in the form of an
advice or recommendations, along with a rationale for each recommendation and its expected benefit. The
recommendation relates to collection of statistics on objects (C), creation of new indexes, restructuring of the
SQL statement (E), or creation of a SQL profile (A). You can choose to accept the recommendation to
complete the tuning of the SQL statements.
