Воспользовался данной нотой, и теперь localhost:7001/apex/lisenerConfigure: выдает ошибку

Не пойму что ему нужно? :(



Configuring Additional Databases

When you first configure the listener, you configure a default database connection named: apex. You can create additional database connections using the setup command.

Tip:
To see full help for the setup command type:

java -jar apex.war help setup

To create a database connection type the following:

java -jar apex.war setup --database <database name>

Where:

<database name> is the name you want to give the database connection.

You are prompted to enter the information required to configure the database. See "Configuring Oracle Application Express Listener" for more information on the data that must be entered.

Once you have configured the additional databases proceed to the next step to define the rules for how requests are route to the appropriate database.
