A Database Connector object (SQL CONN) has been created. When the validity of the referenced database is checked though the button 'Test Connection', the test aborts and returns the error message: 

U00011021 Host 'DB Service Agent' is not active!

The Database Service is not started on the is One Automation System.

The solution is to start the Database Service over the Service Manager Dialog.

The Database Service must be started with this kind of command : 

java -jar -Xmx256M <path to SQL agent>\bin\ucxjsqlx.jar -service -i<path to SQL agent>\bin\ucsrv.ini

If a similar Service is not created already in the Service Manager Dialog it must be added.
