Resetting from bad Access Paths – be they static or dynamic – clarifying the rather opaque IBM Plan Stability Management
This 20 minutes webinar introduces you to our new pocket tool: RUNSTATS Rescue.
In this webcast we show you the complete RUNSTATS Rescue interface with live demos!
RUNSTATS Rescue gathers all the DB2 Optimizer-relevant statistics and saves them away on a regular basis. When you have a “bad” access path (that you have discovered through SQL Monitoring, or telephones ringing), you can very simply reset the DB2 Catalog Optimizer-relevant statistics to a point in time where the SQL Access path was better, thus rescuing you from the perils of bad access paths.
Primarily designed for dynamic SQL, there is also a static SQL extension available, and we have even added a nice SOFTWARE ENGINEERING “front end” for IBM Plan Stability so that both methods of saving Static SQL are supported.
