Finding Right plan against multiple HASH VALUE
Experts,
How would i conclude Optimizer is using correct plan.
1) One SQLID have many hash values. If so , how do i conclude exactly correct hash or plan for my sql_id ? Dol i need to check AVG Execution time for all plans in history.
Is this only option ?
2) After creation of index with parallel , do i need to reset to 0 explicitly.
If i do not reset to 0, how does it impact my performace.
Regards,
