Regardless of the database system used, the PPM server needs the following database objects:
To keep up the performance of your PPM system, it is recommended that you have database system statistics calculated on a regular basis. The administrator of your database is the best person to take care of this.
If you use Oracle as a database system for PPM, you can calculate the object statistics using the -genstats argument of the runppmimport command line program during data import. Further information is available in the command line program's help which you call up with runppmimport -h. Particularly for newer Oracle versions, we recommend administrative statistics calculation instead of the PPM-controlled calculation.
