Q

Optimizer missing statistics on Alert Display

On the Alert Display, I am getting the following: "Object Name - Optimizer (Missing statistics)." How can I eliminate this? What do I have to update to correct this condition, and how do I go about this? Please advise.

The optimizer is missing statistics that it needs in order to make informed decisions. The DBMS_STATS package can be used to calculate statistics on these objects. There are many options with the DBMS_STATS package, so I would suggest looking at the Oracle documentation to determine how to best use this supplied package:
