Installing and Upgrading CDOS for Control Desktop

Installing and Upgrading ENVOX r Configuration Software on DEC VAX and DEC AXP Systems (Revision B — May 1998)
12.3 Preparing for the Installation or Upgrade
Several actions are required before you make any attempt to install or
upgrade CDOS software.
12.3.1 Precautions
Before you install or upgrade, you should understand the precautions
listed below. They can save you time and can reduce the possibility of
errors.
J If you have previously installed a pre-release version of the CDOS
P1.0 software, it must be de-installed before installing the current
release of CDOS software.
J Control Desktop and CDOS, versions P2.0, will only operate with
ENVOX software, version P4.0. Be sure your ENVOX system has
been upgraded to version P4.0.
J The CDOS software will only install or upgrade if ENVOX P4.0 has
been installed in client-server or client-only mode. If you need to
install ENVOX software in one of these modes, refer Section 4.
J ENVOX databases added which are to be used with Control Desktop
must be upgraded to contain certain additional database tables and
procedures. ENVOX databases on ENVOX P3.4 systems running
CDOS P1.0 are automatically upgraded by the ENVOX P3.4 to P4.0
upgrade. Any ENVOX databases added after the upgrade must be
manually upgraded. Once Control Desktop and CDOS are installed,
be sure to upgrade these ENVOX databases. See “Upgrading
ENVOX Databases” in the Control Desktop user manual.
J The installation produces a log file called cdos_inst.log in the default
directory. Keep this log for reference to help you determine probable
causes if the installation fails.
J Once installation or upgrade has started, do not try to interrupt it.
J Before attempting the CDOS installation or upgrade, make sure that
there are no ENVOX users using the system and that no application
software or user processes that access the SYBASE server are
running.
J Appropriate TCP/IP software must be installed on the host system.
The TCP/IP software must also be running; otherwise, the installation
cannot resolve TCP/IP addresses and port numbers.
J The interfaces file must contain a TCP/IP entry for each SYBASE
server to be accessed by Control Desktop, and the SYBASE server
must be restarted.
