Hi Expert,

I am new to BASIS.

I am facing a strange issue.

When i stop listener service in my SAP system, I am still able work on my SAPGUI and do the changes in system and my database.

R3trans -d shows database not connected.

As far as i know, Listener is used for connecting the database at R/3 level.

Please tell me what is happening.

Hi Deepak,

Listener run only at the creating a new connection to the database, phase. Once workprocess started and connected to the database shadow work process, the listener complete its task.

>> R3trans -d shows database not connected.

When you execute the R3trans command, the system try to connect to the database by using listener. If the listener is not running, you face with the connection error.

Another scenario is, for example one of the SAP workprocess have been killed by administrator during the runtime. If listener is not run, newly forked SAP workprocess cannot connect to the database and cannot be started.

I hope that it is clear.

Best regards,
