Question

I have read this post and this excellent article

My question is, how to get the acutual execution plan in Oracle 11g

without sys privilege and DBA privilege. (You can treat my case as a READ-ONLY user)

I’m able to get the explain plan using SYS.PLAN_TABLE$ or CTRL+E in TOAD

But my understanding is that explain plan = estimated execution plan only?

Found on Oracle’s Document

Execution plans can differ due to the following:

• Different Schemas

• Different Costs

Please give me any help you can offer to clear my concepts.

Answer 1

If you want to use dbms_xplan.display_cursor, you’ll need at least these grants:

grant select on sys.v_$sql_plan to larry;
grant select on sys.v_$session to larry;
grant select on sys.v_$sql_plan_statistics_all to larry;

And you’ll probably also need V$SQL to find the SQL_ID:

grant select on sys.v_$sql to larry;
