db.properties file
The db.properties file contains properties that are used by the Windchill persistence layer to access the database. They can be set in the wt.properties file but are usually kept in a separate file identified by the wt.pom.properties entry. Because a password is contained in this file, you should maintain it in a secure location. The values in the separate file override the values in the wt.properties file.
In the db.properties file, you must set the following properties:
wt.pom.dbUser, which specifies the Oracle user name you or your Oracle administrator defined for you. This user is the owner of Windchill tables and stored procedures. There is no default; it must be set.
wt.pom.dbPassword, which specifies the Oracle password you or your Oracle administrator defined for you. There is no default; it must be set.
wt.pom.serviceName, which is the service name you or your Oracle administrator created. There is no default; it must be set.
