User-Definable Environment Variables
Some Actian X environment variables 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 Actian X environment variables set system-wide.
Linux: A good place to set user-defined environment variables is the user’s profile file.
Example: Set an Environment Variable in the Local Environment
An environment variable typically set in the user’s local environment is TERM_INGRES. It specifies the termcap definition to be used by the forms system. It can be redefined locally by entering commands at the operating system prompt as in the following example:
Windows:
SET TERM_INGRES=IBMPCD
Linux:
TERM_INGRES=vt100f export TERM_INGRES
Display Current Value for Variables
A user can display the values set in their environment with the following command entered at the operating system prompt:
Windows:
SET
Linux:
env
Environment Variables that Can Be Reset Locally
