Installing and Upgrading ENVOX r Configuration Software on DEC VAX and DEC AXP Systems (Revision B — May 1998)
12.4 Licensing CDOS After Installation
After installation, you must obtain license keys. The CDOS installation
program creates a license file, cdos_system:[cdos]license.dat. This file
lists the purchased Control Desktop licenses. The list is used by CDOS to
identify when the number of licenses has been exceeded.
The CDOS installation program also creates a license expiration file,
cdos_system:[cdos]expiry.dat. This file provides CDOS with a license
expiration date one month from the date CDOS is installed. The file also
contains an encryption code which allows CDOS to identify if the
expiration date has been modified or if the file has been copied from
another machine.
Do not attempt to copy an expiration or license file from another
machine, nor modify it, because it will not be useable.
Note ...
The installed version of the license file in combination with the license
expiration file allows a 29-day grace period (from the date of installation)
during which time CDOS accepts a pre-defined number of Control
Desktop and Control Designer users. Once the grace period has expired,
Control Desktop will not operate unless new license keys have been
obtained from Fisher-Rosemount Systems. The license keys are specific
to the licenses that have been purchased and the machine on which
CDOS has been installed.
You should not wait until the grace period has expired before obtaining
your own license keys. As soon as possible after installation, use the
Control Desktop application to obtain license keys. Also, if CDOS is
moved to another machine, and in some other circumstances, new
license keys need to be requested from FRSI. Full details of how and
when to obtain new license keys are given in the Control Desktop, Getting
Started manual.
Control Desktop and CDOS software are licensed simultaneously. To
obtain the license keys, perform the procedures described in Software
Licensing Procedure of the Control Desktop getting started manual.
