Hi guys,

I just stumbled across the catalog table SYSSTATSFEEDBACK. According to IBM it should save some recommendation for the RUNSTATS utility. So I searched the IBM knowledge center and only found this entry
https://www.ibm.com/support/knowledgecenter/SSEPEK_11.0.0/cattab/src/tpc/db2z_sysibmsysstatfeedbacktable.html

But my problem is to understand what to do with all that information. For example: REASON = DEFAULT. The description says
Quote:
A predicate references a value that is probably a default value.

So what? What kind of RUNSTATS do I have to run in order to support the optimizer with more helpful statistics?

Is there some kind of redbook that discusses the topic of SYSSTATSFEEDBACK?

Thanks for the feedback.
