Configuring the Database Application User After Updating
If your Windchill installation is configured with a database application user, and you want to add new Windchill features or components that result in a schema change then the following steps must be followed:
1. Configure Windchill with database install user
Stop the Windchill Server.
From a Windchill Shell execute the following statements to update Windchill database properties to reflect the Windchill database installation user:
xconfmanager -s wt.pom.dbUser=< WINDCHILL_INSTALL_USERNAME > -t "db/db.properties" -p

xconfmanager -s wt.pom.dbPassword=<WINDCHILL_INSTALL_PASSWORD> -t "db/db.properties" -p
Start the Windchill Server.
2. Add the new features or components to your Windchill installation.
3. For Oracle databases only: Grant access to newly created database objects:
Using Sqlplus, login to the database as database admin user, and execute the script <WT_HOME>/db/sql/update_wc_app_role_privs.sql to grant privileges to the new schema objects.
4. When prompted provide the following values:
Windchill Install database User Name: <WINDCHILL_INSTALL_USERNAME>
 Windchill Application database Role Name: <WINDCHILL_APP_DATABASE_ROLE>
5. Configure Windchill with the database application user:
Stop the Windchill Server.
From Windchill Shell execute the following statements to update Windchill database properties to reflect Windchill database installation user:
xconfmanager -s wt.pom.dbUser=< WINDCHILL_APP_USER_NAME> -t "db/db.properties" -p
xconfmanager -s wt.pom.dbPassword=<WINDCHILL_APP_USER_PASSWORD> -t "db/db.properties" -p
Start the Windchill Server.
