Note:Oracle strongly recommends that you use SQL plan management for new applications. SQL plan management creates SQL plan baselines, which offer superior SQL performance stability compared with stored outlines.
You can migrate existing stored outlines to SQL plan baselines by using the
MIGRATE_STORED_OUTLINE function of the
DBMS_SPM package or Enterprise Manager DB Control. When the migration is complete, the stored outlines are marked as migrated and can be removed. You can drop all migrated stored outlines on your system by using the
DROP_MIGRATED_STORED_OUTLINE function of the
