Linux environment variables are set at the shell level. These are in effect before, during, and after Vector is invoked. There are several variables required for Vector. These variables are set by the .ingXXsh script, which is generated in the home directory of the administrative user (typically actian).

To make the environment global, you can copy/link the script to /etc/profile.d and remove the "." so it is not hidden.

To source the environment automatically for the actian user, add . ~/.ingXXsh to the .bashrc file.
