Dear all,

Can we delete specific execution plan for a statement?

https://docs.oracle.com/database/121/TGSQL/tgsql_spm.htm#TGSQL658

as far I as I know, the above will only delete from the sql baseline, it will not delete from the database cache.

from https://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:4092356300346664639

alter system flush buffer_cache;
SQL> alter system flush shared_pool;

alter system flush shared_pool;

the above flushes the whole database buffer not a specific sql.

Can we delete specific execution plan in the db buffer for a statement

thanks a lot!
