E
Server Statistics

The DBMS_STATS package generates statistics for the entire Oracle Email table or index. Statistics are transferred between the statistics table and data dictionary, and can be used only when they are stored in the data dictionary. The statistics table enables users to export or import statistics from one database to another. Oracle Email includes statistics that are collected from a mature system, because there is not enough statistical data when the system is first installed. Users can choose to import these statistics into their systems prior to using their own statistics.

This appendix contains the following topics:
