Some Ingres environment variables and logicals can be set or reset by individual users in their local environment using operating system commands. Those set in a user’s local environment supersede the Ingres environment variables and logicals set system-wide.

UNIX: A good place to set user-defined environment variables is the user’s .login (for the C shell) or profile (for the Bourne Shell) file.

VMS: Individual users can define Ingres environment variables at the job or process level with DCL commands, or they can be defined in the user’s login.com file.
