If you get Tom Kyte's book
(Expert One-on-One Oracle. from Wrox press)
the Java chapter has an item on running O/S
commands from within PL/SQL. You could
use this method as a basic tool for discovering
values of environment variables; and may give
you ideas about how to implement your
requirements.
