Windchill System Requirements
To run the Windchill Configuration Assistant successfully, your installed Windchill system must have base data loaded. Loading base data is required for all Windchill solutions and is selected by default when Windchill is installed.
You can run the assistant regardless of the type of database you have installed. The properties related to database cache sizes are updated by the assistant for both Oracle and SQL Server databases.
