The only users who can issue these commands are the “sa” user and the Monitor Server superuser. The superuser is the account named or implied in the -U parameter of the Monitor Server start-up command.
To use these commands, open an isql session and connect to the Monitor Server that you want to stop or obtain status information about. Use the following command syntax:
isql -Uusername -Ppassword -SmonitorServerName
username is the name specified with the -U parameter to the Monitor Server start-up command.
password is the password for username.
monitorServerName is the Monitor Server you want to stop or obtain status information about.
