Log On to the CommServe

To run command line operations, you must first login to the CommServe.

From Command prompt, navigate to <Software_Installation_Directory>/Base and run the following command:

qlogin -cs <commserve name> -u <user name>

For example, to log on to CommServe 'server1' with username 'user1':

qlogin -cs server1 -u user1
