Real-time SQL Plan Management 

Real-time SPM quickly detects and repairs SQL performance problems caused by execution plan changes.
If a SQL statement has been running well, but a plan change causes it to perform poorly, real-time SPM detects this immediately. If it establishes that a previous plan will perform better, it will reinstate it using a SQL plan baselines.
This automates what some DBAs do already: they create SQL plan baselines to target individual SQL statements with intermittent performance issues and enforce a plan that is known to be good.
