When using the Oracle Database for the storage of WebLogic Portal settings you need to modify the database.properties and run the create_db.sh script. In the database.properties the example uses the Pointbase, so the values in the Oacle section are filled with placeholders. When replacing the jdbc string be carefull not to remove all @ signs. The original value is: oracle.url=jdbc:oracle:thin:@@DB_HOST@:@DB_PORT@:@DB_NAME@ The fisrt @ after the 'thin:@' needs to remain there. Otherwise you will get a sql exception when you run the create_db.sh script.
Some of the stuff I do for a living. This mainly concerns working with Oracle Databases and Application Servers. Lately I picked up AWS, Azure and OCI.
