How can I force a stored outline from sqlplan in the past that is in dba_dba_hist_sql_plan

Hi,

We have noticed a performance issue with our batch processing.  After bounce the batch processing went fine.  Notice the top SQL has taken a different path now (different plan) altogether.  We have reporting database that is previous day of the OLTP production database.  I can see the bad and good plan in the dba_hist_sql_plan.  I wanted to force the sql to take the bad plan using stored outlines and test the batch issue.  Please advise how I can do this.

I know if the sql plan is in the v$sql I can used dbms_outln.create_outline to create stored outlines.  How can I do the same if the plan is in the history that I want to enforce.

Howdy, Stranger!
