To upgrade your system to SR 5.0, you will need to execute commands and scripts as 
both root and dncs user on the DNCS as well as the Application Server. For this 
reason, we recommend opening a total of three xterm windows: one that accesses 
the DNCS server as root user, one that accesses the DNCS server as dncs user, and 
one that accesses the Application Server. 
Important:  Once this procedure is complete, we will refer to either the root or the 
dncs xterm window on the DNCS or the xterm window on the Application Server 
for the remaining procedures in this document. 
Complete the following steps to open the xterm windows. 
1 

Open three xterm windows on the DNCS system. 

2  In one xterm window, change to root user by completing the following steps. 

a  Type su - and press Enter. The password prompt appears. 
b  Type the root password and press Enter. 

In the second xterm window, type id and press Enter to verify that you are 
logged in as dncs user. 
Example:   

4  Is the ID (uid) of the second xterm window dncs? 



 

If yes, go to step 5. 



 

If no, type the following command and press Enter. Then, repeat steps 3  
and 4. 

In the third xterm window, type the following command and press Enter to 
access the Application Server. 

6  Complete steps 2a and 2b to switch to root user in the Application Server xterm 

window.
