NEW QUESTION: 3
Which three statements are true about adaptive SQL plan management?
A. It adds new, bettor plans automatically as fixed plans to the baseline.
B. The non-accepted plans in a SQL plan baseline are automatically evolved, in COMPREHENSIVE mode, during the
nightly maintenance window and a persistent verification report is generated.
C. It automatically performs verification or evolves non-accepted plans, in COMPREHENSIVE mode when they
perform better than existing accepted plans.
D. The non-accepted plans are automatically accepted and become usable by the optimizer if they perform better
than the existing accepted plans.
E. The optimizer always uses the fixed plan, if the fixed plan exists in the plan baseline.
Answer: B,C,D
Explanation:
With adaptive SQL plan management, DBAs no longer have to manually run the verification or evolve process for non-
accepted plans. When automatic SQL tuning is in COMPREHENSIVE mode, it runs a verification or evolve process for
all SQL statements that have non-accepted plans during the nightly maintenance window. If the non-accepted plan
performs better than the existing accepted plan (or plans) in the SQL plan baseline, then the plan is automatically
accepted and becomes usable by the optimizer. After the verification is complete, a persistent report is generated
detailing how the non-accepted plan performs compared to the accepted plan performance. Because the evolve
process is now an AUTOTASK, DBAs can also schedule their own evolve job at end time.
Note:
* The optimizer is able to adapt plans on the fly by predetermining multiple subplans for portions of the plan.
* Adaptive plans, introduced in Oracle Database 12c, enable the optimizer to defer the final plan decision for a
statement until execution time. The optimizer instruments its chosen plan (the default plan) with statistics collectors
so that it can detect at runtime, if its cardinality estimates differ greatly from the actual number of rows seen by the
operations in the plan. If there is a significant difference, then the plan or a portion of it will be automatically adapted
to avoid suboptimal performance on the first execution of a SQL statement.

NEW QUESTION: 3
Which three statements are true about adaptive SQL plan management?
A. It adds new, bettor plans automatically as fixed plans to the baseline.
B. The non-accepted plans in a SQL plan baseline are automatically evolved, in COMPREHENSIVE mode, during the
nightly maintenance window and a persistent verification report is generated.
C. It automatically performs verification or evolves non-accepted plans, in COMPREHENSIVE mode when they
perform better than existing accepted plans.
D. The non-accepted plans are automatically accepted and become usable by the optimizer if they perform better
than the existing accepted plans.
E. The optimizer always uses the fixed plan, if the fixed plan exists in the plan baseline.
Answer: B,C,D
Explanation:
With adaptive SQL plan management, DBAs no longer have to manually run the verification or evolve process for non-
accepted plans. When automatic SQL tuning is in COMPREHENSIVE mode, it runs a verification or evolve process for
all SQL statements that have non-accepted plans during the nightly maintenance window. If the non-accepted plan
performs better than the existing accepted plan (or plans) in the SQL plan baseline, then the plan is automatically
accepted and becomes usable by the optimizer. After the verification is complete, a persistent report is generated
detailing how the non-accepted plan performs compared to the accepted plan performance. Because the evolve
process is now an AUTOTASK, DBAs can also schedule their own evolve job at end time.
Note:
* The optimizer is able to adapt plans on the fly by predetermining multiple subplans for portions of the plan.
* Adaptive plans, introduced in Oracle Database 12c, enable the optimizer to defer the final plan decision for a
statement until execution time. The optimizer instruments its chosen plan (the default plan) with statistics collectors
so that it can detect at runtime, if its cardinality estimates differ greatly from the actual number of rows seen by the
operations in the plan. If there is a significant difference, then the plan or a portion of it will be automatically adapted
to avoid suboptimal performance on the first execution of a SQL statement.
