Specifications

OpenVMS Operating System for Alpha and VAX (Versions 7.1, 7.1–1H1, 7.1–1H2, and 7.1–2) SPD 41.87.06
Test Package and Diagnostics
OpenVMS includes a User Environment Test Package
(UETP), which verifies that the OpenVMS operating sys-
tem is properly installed and ready for use on the cus-
tomer’s systems.
You can run diagnostics on individual devices during
normal system operation. Certain critical components
can operate in degraded mode.
OpenVMS Alpha DISK SPACE REQUIREMENTS
Operating System Disk Space Requirements
The disk space requirements for OpenVMS Alpha vary
according to which options are installed:
File Category
Space
Used Running Total
Minimum OpenVMS files 95 MB 95 MB
Other OpenVMS files 89 MB 184 MB
Paging file (required) 38 MB 222 MB
Swap file (suggested) 3 MB 225 MB
Dump file (optional) 28 MB 253 MB
Decompressed Help files
(optional)
15 MB 268 MB
Full DECwindows Motif
V1.2-4 (optional)
90 MB 333 MB
Safeguard for upgrading 50 MB 383 MB
The minimum OpenVMS files listed in the table are for
a system configuration where all optional features have
been declined during the initial installation. For most ap-
plications, this is not a realistic OpenVMS environment.
The paging, swap, and dump file requirements are the
minimum for a system with 32 MB of main memory.
Additional memory in most cases adds to the space
needed for these files, as will particular needs of your
application. With careful system management it is pos-
sible to use the paging file space as a temporary dump
file.
For an OpenVMS Cluster system disk, paging, swap,
and dump files cannot be shared between nodes, so
the files must either be duplicated on the system disk or
located on some other disk.
DECwindows Motif for OpenVMS Alpha Disk Space
Requirements
To support OpenVMS Alpha and DECwindows Motif for
OpenVMS Alpha, Compaq recommends a system disk
of greater than 480 MB. However, you can install a sub-
set of DECwindows Motif. The disk space required for
the installation of DECwindows Motif is 90 MB. The per-
manent amount of space used is 89 MB. An additional
33 MB is needed to install the DECwindows X11 Dis-
play Server and associated files. (The DECwindows
X11 Display Server and associated files are included in
the OpenVMS Alpha Version 7.1 media.) These disk
space requirements are in to addition the disk space
required for the OpenVMS Alpha Version 7.1 operating
system, as indicated in the OpenVMS Alpha Disk Space
Requirements table.
Installation of the DECwindows Motif Version 1.2-4 lay-
ered product gives customers the option of installing any
or all of the following components:
• Run-time support base kit — 25 MB. This sec-
tion provides support for running DECwindows Motif
for OpenVMS Alpha applications on Alpha compute
servers and is a required part of the installation.
• New Desktop — 21 MB. This is an optional com-
ponent that allows use of the New Desktop environ-
ment. It includes applications and application pro-
gramming interfaces (APIs).
• DECwindows desktop — 4 MB. This component is
also optional, but you should install either the New
Desktop or the DECwindows desktop to create a us-
able system. The DECwindows desktop is the user
interface that was included in previous versions of
DECwindows Motif and includes the DECwindows
Session Manager, FileView, and the Motif Window
Manager.
• Programming support — 7 MB. This section in-
cludes support for the DEC C, DEC C++, DEC
Fortran, and Pascal programming languages. If you
install a subset of languages, the amount of disk
space required will be less.
• Example file — approximately 7 MB.
• Translated image support — approximately 17 MB.
Layered Product Disk Space Requirements
In addition to the disk space used directly by Compaq
or third-party layered products, there may be additional
space used to store information from those products
in OpenVMS help libraries, command tables, object li-
braries, and elsewhere. The amount of additional disk
space required cannot be exactly predicted due to the
possibility of recovering unused space already existing
in those library files. Unusually large modules con-
tributed by layered products can also affect the amount
