question about execution plan if the SQL can't be executed in parallel

edited May 17, 2011 3:40PM in Database Tuning (MOSC) 12 commentsAnswered ✓
 Hi All,
I know when oracle finds that no resource is available for processing one sql in parallel, it will execute it serially.
But what will happen to the execution plan of this sql?

Since the execution plan was generated at parse stage is parallelized, will the sql be re-parsed to generate a new serial plan?

Best regards,
Leon
