A user who is responsible for running Ingres requires the Operator privilege.

These system commands can alternatively be run through the Remote Command (rmcmd) Server by a (client) user who has the rmcmd privileges rather than the Operator privilege (assuming that the user who launched rmcmd on the server side has the Operator privileges). The sysmod command, however, requires the client user to have the security privilege or be the user who launched rmcmd on the server side. For details, see Grant Access to Remote Users and How Remote Commands Are Executed in the System Administration Guide.

The Protected_User privilege is assigned to the installation owner and root user (in Linux) during installation. A user with the “Protected_User” privilege cannot be dropped, altered or have its password changed by other users, except the installation owner and self.
