The plans can be manually loaded to the SQL plan baseline.
The plans in the SQL plan baseline are verified and accepted plans.
The plans generated for every SQL statement are stored in the SQL plan baseline by default.
The plan baselines are stored temporarily in the memory as long as the database instance is running.
For the SQL plan baselines to be accessible to the optimizer, the SYSAUX tablespace must be online.
