Installing and Upgrading ENVOX r Configuration Software on DEC VAX and DEC AXP Systems (Revision B — May 1998)
5.1 Before Upgrading SYBASE and ENVOX Software
Severa l procedures and considerations need to be done before you
perform an installation. They are explained in the following subsections.
5.1.1 Precau tio ns
Before you upgrade, you should understand the precautions listed
below. They can save you time and can reduce the possib ility of errors.
J Make adequate backups of the system and perform the dumps of
your configuration data prior to upgrading. These actions ensure that
the system software and databases can be recovered if the upgrade
fails.
J For ENVOX P2.x, P3.0, P3.2, and P3.3, the SYBASE System 10.0
database will be larger than your present database by at least 26%.
ENVOX P3.4 is already at SYBASE 10.0.
J Determine the database structure and statistics of your system.
Subsections 5.2.1 and 5.3.1 contain instructions for obtaining this
information.
J Save the printout of the show_dev_alloc.out file for future reference
in case you need to return to the previous configuration.
J Make sure that no application software or user processe s that access
the SYBASE SQL server are running during the upgrade.
J Validate the integrity of all databases (except for tempdb) by running
the database checks described in the System Manager ’s Guide to
ENVOX Configuration Software, SM1.0:SW3151, for ENVOX release
P4.0. See the list of ENVOX manuals in subsection 1.7. Any errors
should be reported to your Fisher-Rosemount Systems’
Representative or sales office so that the errors can b e corrected
before upgrading.
J Do not initialize the second disk; see the following:
Do not initialize the second disk for an upgrade because
initializing the disk erases all of the data on the disk.
