SQL Plan Management is not part of the Tuning Pack. It is a free tool available to all users of Oracle Enterprise Edition. What Kyle found in the Oracle documentation is a documentation bug. The wording implies you need the Tuning Pack when you don’t. SQL Plan Management works in conjunction with the Tuning Pack specifically the auto SQL Tune feature but is not part of it.
Automatic Plan Evolution of SQL Plan Management means if the Auto SQL Tune advisor finds a better plan for a SQL statement that has a SQL Plan Baseline that plan will be automatically added to the plan baseline as an accepted plan. Nothing more. More info on this can be found in this white paper http://www.oracle.com/technetwork/database/features/bi-datawarehousing/twp-sql-plan-management-11gr2-133099.pdf

here’s a link:
http://68.142.116.68/docs/cd/B28359_01/license.111/b28287/options.htm
says
“Automatic Plan Evolution of SQL Plan Management”
is part of the Tuning pack. Still unclear as to which commands are part of the pack and which or not.

Hello,

It looks like, I was wrong when I wrote that… Even if Oracle is not very clear about the SPM feature that is actually included in the Tuning Pack.

If you refer to the licensing guide, regarding Tuning Pack), it says:

Oracle Tuning Pack includes the following features:
[...]
* Automatic Plan Evolution of SQL Plan Management

The question is What is “Automatic Plan Evolution of SQL Plan Management” ? Obviously if you search the documentation for this feature, you find it only in the Licensing Guide.

I’ve disabled the Tuning pack and change the value and it doesn’t fail. The licensing terms suggest that’s actually included in that case! or, maybe, Oracle disables the feature, in spite of the parameter and doesn’t tell:
SQL> alter system set control_management_pack_access=DIAGNOSTIC;

System altered.

SQL> alter system set OPTIMIZER_CAPTURE_SQL_PLAN_BASELINES=true;

System altered.

So it’s worth more testing (at least to me) to figure out what exact part of SPM is included in the Tuning Pack Only!

where is it documented that optimizer_capture_sql_plan_baselines is part of the Tuning Pack?
followed the link at top “optimizer_capture_sql_plan_baselines (Tuning Pack)” but didn’t see any reference to the Tuning Pack.
Did a google search but didn’t see anything in the first 10 hits
