Anyone aware of a way to create a sql profile without running the sql
tuning advisor? I have 6 plans associated with the same sql stmt and I
want to create a profile based on the execution path from today's run.
1 select sql_id, plan_hash_value, max(timestamp) from dba_hist_sql_plan
where
2 sql_id = '206z4tq4j0yrp' group by sql_id, plan_hash_value
3* order by 3
SQL> /
SQL_ID PLAN_HASH_VALUE MAX(TIMESTAMP)
------------- --------------- --------------------
206z4tq4j0yrp 2840312503 13-AUG-2008 04:30:14 206z4tq4j0yrp 2136351662 20-AUG-2008 04:38:25 206z4tq4j0yrp 502714015 21-AUG-2008 04:42:30 206z4tq4j0yrp 1813612 22-AUG-2008 04:40:20 206z4tq4j0yrp 3184831364 26-AUG-2008 04:25:56 206z4tq4j0yrp 3939223844 27-AUG-2008 04:29:42
6 rows selected.
I'm just curious if there's a way to shorten the process vs creating the tuning task, getting it from the cursor cache, executing the tuning task, accepting the profile....
Thanks - Brian
