Opening a Service Session: -uSRV 

Use

Option when Calling the Database Manager CLI

Certain DBM Server commands require a service session before they can be executed.

If you specify this option this option, the DBM Server command for opening a service session is executed implicitly.

If you exit the Database Manager CLI (DBMCLI) and therefore the DBM Server, the service kernel is also stopped.

You are also using the option -d at the same time to specify a database instance and the option -u to log on to the DBM Server.
