Your system has been upgraded from Oracle Database 10g to Oracle Database 11g. You
imported SQL Tuning Sets (STS) from the previous version. After changing the
OPTIMIZER_FEATURE_ENABLE parameter to 10.2.0.4 and running the SQL Performance
Analyzer, you observed performance regression for a few SQL statements. What would you
do with these SQL statements?
A.
Set OPTIMIZER_USE_PLAN_BASELINES to FALSE to prevent the use of regressed
plans.
B.
Set OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES to FALSE to prevent the plans
from being loaded to the SQL plan baseline.
C.
Capture the plans from the previous version using STS and then load them into the
stored outline.
D.
Capture the plans from the previous version using STS and then load them into SQL
Management Base (SMB).
