For example, in the SDSF screen, enter the following command:

'/s ATTDAEMN'

Where

 INSTROOT

 is the high-level qualifier where Oracle Connect is installed.

Shutting Down the Daemon

To shut down the daemon use Oracle Studio, as follows:

1.

From the

3.

Right-click the computer and select

 Open Runtime Perspective

.

4.

In the Runtime Explorer, right-click the computer and select 

Shutdown Daemon

.

Monitoring the Daemon During Run Time

Use the Runtime Manager perspective of Oracle Studio to monitor the daemon during
