stored outlines – fixed execution plan

stored outlines are designed to force a specific sql-statement to use a fixed execution plan.
This execution plan will be used even the table or the environment changes.
Using stored outlines is dependend on the hash_value (in 10g) / sql_id (in 11g).

In 11g a new feature was implemented – the sql plan managment.
This is a great extension to guarantee save plans.
