PRODUCT NAME:

The ULTRIX Operating System, Version 4.5

Description
The ULTRIX Operating System, Version 4.5 is Digital Equipment Corporation’s native implementation of
the UNIX® Operating System for all currently supported VAX, MicroVAX, VAXstation, VAXserver and Digital RISC DECsystem and DECstation systems.
The ULTRIX Operating System is an interactive,
demand-paged, virtual memory, multiple processor,
time-sharing operating system that has a hierarchical file
system with dismountable volumes, compatible device
and interprocess I/O, asynchronous processes, system
command language selectable on a per-user basis, disk
quotas, job quotas, over 200 subsystems, and a high
degree of portability among processors running ULTRIX
application programs.
In addition to the Berkeley 4BSD functionality, Digital
has added the following enhancements to ULTRIX:

File System
The ULTRIX Operating System provides a file system hierarchy of named directories and sub-directories. With
the ULTRIX Operating System, the Digital Generic File
System Interface (GFSI) provides users with the ability
to mount multiple local and remote file systems. The
currently supported file system types include the local
ULTRIX File System (UFS) and Sun® Microsystems’
Network File System (NFS). NFS allows transparent
file access over an Ethernet or CI network. POSIXcompatible file and record locking is supported by the
NFS lock manager over an Ethernet or CI network. In
addition, Sun MicroSystems’ Yellow Pages service (YP)
provides support for centralized system management of
files over an Ethernet or CI network. The automounter
service automatically mounts and unmounts NFS file
systems.

operations and are useful in database applications. The
file system buffer cache size is configurable.
ULTRIX provides an option to provide I/O performance
enhancement improving both UFS (Local) and NFS.
Virtual Memory
The virtual memory subsystem is derived from 4.2BSD
and has been enhanced with 4.3BSD performance enhancements and System V™ memory extensions. It
provides full demand paging for both files resident on a
local file system and files remotely resident and accessible via NFS. The backing store for paging/swapping
can reside on a local disk partition or, in the case of
diskless support, in an NFS remote system file. System V features include demand paged shared memory
support and page locking.
The ULTRIX virtual memory programmer’s interface provides full source level compliance to existing standards.
New interfaces of SVID issue 3 are not currently supported.
Multiprocessor Support
The ULTRIX kernel has been enhanced to support multiple processors executing kernel code. Support has
been added for both RISC and VAX multiprocessor systems. Semaphores and spin locks synchronize access
to kernel data structures. Each processor shares a common kernel image of text and data. The commands
startcpu and stopcpu control attached processors. The
cpustat utility views various cpu statistics.
OPEN SCSI CAM

ULTRIX supports synchronous file system writes on a
per-file basis. In addition, an option to the ‘‘mount’’ command permits an entire file system to be designated as
synchronous, in which case all writes issued to files in
that file system are performed synchronously. These
synchronous options provide deterministic file system

SPD 26.40.32

ULTRIX RISC includes OPEN SCSI CAM, a new software architecture for the SCSI hardware sub-systems
in ULTRIX. This architecture uses Common Access
Method (CAM), a standard defined software interface
between device drivers and the host bus adapter by
which SCSI peripherals are attached to a host processor. With this well architectured interface, system manufacturers, system integrators, controller manufacturers,

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

and other suppliers of intelligent peripheral are able to
more easily write the necessary drivers and support
code for other third party devices.

• Security auditing subsystem and audit trail reduction facility which tracks and records all the security
relevant actions occurring on the system along with
who performed the action. This includes an audstyle
(audit) option to control how much information is included in audit records for execv (2) and execve (2)
events.

OPEN SCSI CAM is not available on VAX ULTRIX systems. ULTRIX RISC does not support the use of SCSI
devices on DECsystem 5800 systems.

• Gateway packet screening. An ULTRIX system may
be used as a gateway (packet router) to connect several IP networks. The Gateway packet screening
facility allows the system manager to control which
packets are forwarded, as one part of a comprehensive network security policy. The facility consists of a
kernel-resident mechanism and a user-level daemon,
/usr/etc/screend. When a packet is ready to be forwarded, the kernel mechanism submits the packet’s
headers to the daemon. The screend daemon examines the headers and tells the kernel to forward
or reject the packet, based on a set of rules defined
in the configuration file, /etc/screend.conf. Optionally, some or all decisions can be logged allowing a
manager to detect improper configurations or potential security problems.

System Administration Enhancements
• Graphical User Account Manager
• Integral bad block replacement for DSA/MSCP and
SCSI disks
• System diagnostics
• Error logging
• Streaming tape
• Remote backup
• Gateway Screen Facility
• Network installation for MicroVAX, VAXstation, and
RISC-based systems

For reasonable security and performance using screend,
Gateway packet screening should be used on a system
dedicated only to packet routing and related support activities.

• Magnetic tape facilities including labeled tape facility for single-volume ANSI tape interchange between
ULTRIX and non-ULTRIX systems

• Kerberos Authentication. Kerberos is a third-party
authentication service. The authentication of an application X to another application Y depends upon
the trust both X and Y have in Kerberos. The BIND
/HESIOD daemon named has been enhanced to optionally use Kerberos. ULTRIX also provides the Kerberos V4 programming interface so that application
developers can use this service. ULTRIX does not
provide the routines to send encrypted (safe) messages.

• Line printer setup automation
• Documented error messages
• Support for up to 256 simultaneous users, available
through the use of user capacity upgrades
• Support for more than 64 file descriptors

Security Enhancements

• Data Encryption/Decryption Facilities. The object
code distribution for the ULTRIX Operating System
includes no forms of encryption or decryption other
than one-way password encryption and Kerberos encryption algorithm. Data encryption/decryption software is available as an option under a separate order
number. Refer to the SOFTWARE OPTIONS section
for ordering information.

The ULTRIX Operating System offers security features
designed to be compliant with the C2 security level as
specified by the Trusted Computing Security Evaluation
Criteria (Orange Book) and the Password Management
Guidelines (Green Book).
• Protection of the memory interface and terminals via
pre-assigned group identifiers.

ULTRIX includes a set of intersystem facilities for communication and networking of multiple systems.

• Trusted Path facility which allows users, logging into
a system via either LAT or a terminal multiplexer, to
ensure that no other process is running on that line.

• Asynchronous Lines
Dynamic reassignment of asynchronous lines allows
use of the same modems for dialing in and out of a system without user intervention. Terminal drivers support
7-bit and 8-bit characters.

• Administrator option to configure enhanced login and
password functionality, which includes a shadow authentication database, configurable minimum password length (up to 16 characters), password aging
and expiration.

• Synchronous Lines

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

ULTRIX VAX supports communication over full- and
half-duplex point-to-point DDCMP synchronous lines.
DMC mode is provided for backwards compatibility. This
feature is not available on ULTRIX RISC systems.

• Name Services
ULTRIX supports the BIND V4.8 and HESIOD name services. The BIND service provides a host name and address lookup service for the Internet network. HESIOD
is layered on top of BIND and provides a more generic
name service. The user can use HESIOD/BIND to replace or supplement the hosts, aliases, auth, group, networks, passwd, protocols, rpc, and services databases.

• Ethernet Support
Ethernet Support allows for Ethernet communication using the TCP/IP network protocols, ThinWire, baseband
and, optionally, the Digital DNA network protocol, if
either DECnet–ULTRIX or DECnet/OSI for ULTRIX is
present (refer to SPDs 26.83.xx and 34.97.xx, respectively). All protocols can operate concurrently on a single physical Ethernet link.

• XTI
XTI is a UNIX® version independent (BSD or System
V) network application programming interface. Most
networking applications are written to sockets since it
is available on most UNIX® systems. Over time, this
trend would shift to the System V interface. With XTI,
customers can write to a standard interface which will
use either streams or sockets.

• CI Network Support
CI Network Support allows for Computer Interconnect
(CI) host to host communication using the network support TCP/IP network protocols. The CI network is well
suited for Network File System (NFS®) traffic and can
be used to offload the Ethernet of NFS traffic.

• The Packet Filter
The packet filter is a software-driven network traffic monitor which provides demultiplexing of networking packet
headers, as well as reception and transmission of packets containing user defined network protocols on an Ethernet LAN. The packet filter functions as an Ethernet
Monitor and can be used to filter specific network protocols. The packet filter can also be used to send and
receive packets using protocols not currently supported
in the ULTRIX kernel.

• X.25 Driver Support
X.25 Driver Support allows for X.25 wide area network
device support.
ULTRIX VAX supports uucp and tip operations over
an X.25 public packet switching network using a MICOM Micro 800/X.25 Concentrator PAD device attached
to one of the supported asynchronous communications
multiplexers. This feature is not available on ULTRIX
RISC systems.

• SNMP

• FDDI Support

Simple Network Management (SNMP) protocol manages TCP/IP networks. ULTRIX supports the SNMP
Agent on both ULTRIX VAX and ULTRIX RISC systems.

FDDI Support provides fiber optic support for the DECsystem and DECstation 5000 systems.

• IBM® 2780/3780 Terminal Emulator
The IBM® 2780/3780 Terminal Emulator is an ULTRIX
software package that allows the user’s system to emulate a 2780 or 3780 IBM terminal. The 2780/3780 Terminal Emulator uses the Binary Synchronous Communications (BSC) protocol to send and receive files across
a communication line connected to an IBM system that
supports 2780/3780 devices.
The Digital devices that must be used on the VAX and
MicroVAX based systems for the ULTRIX 2780/3780
Terminal Emulator are noted in the OPTIONAL HARDWARE section of this Software Product Description.
This package is not available on ULTRIX RISC systems.
• Local Area Transport Support
The Local Area Transport (LAT) protocol supports communication with service nodes on the same Ethernet.
Software that runs on local area terminal servers isdownloaded over the Ethernet network from either a
Phase IV or Phase V loadhost or any valid ULTRIX load
host. A single ULTRIX host may support up to 256 simultaneous LAT sessions.

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

Program Development Enhancements

The host-initiated connection feature of LAT allows the
manager of an ULTRIX system to associate a named
port on a named terminal server with a specific tty device
special file. As a result, users can code applications that
connect to the port through LAT.

ULTRIX provides a variety of tools for program development. These tools include R4000 MIPS-ANSI C 3.0,
VAX C/ULTRIX, portable C compiler, Pascal compilers
and Source Code Control System (SCCS). MIPS-ANSI
C 3.0 is only available on VAX RISC systems. VAX C
is only available on ULTRIX VAX systems. Pascal for
RISC and FORTRAN for RISC are available as a layered product.

The LAT/TELNET Gateway feature allows an ULTRIX
system to be configured for users on a LAT terminal to
connect to remote hosts via Telnet, without first having
to log in to the local ULTRIX system.

• MIPS-ANSI C 3.0 Compiler
• Remote Procedure Call Facility

ULTRIX RISC includes the MIPS-ANSI C 3.0 compiler
and related development tools and libraries. This compiler is not available on ULTRIX VAX systems.

The Digital Remote Procedure Call (DECrpc) facility is based on Apollo®’s Network Computing System
(NCS®) Remote Procedure Call (RPC) facility. DECrpc
allows application developers to partition their applications along subroutine interfaces, and have those subroutines execute on remote hosts. It provides a transport independent interface to applications using the Internet UDP/IP protocols. DECrpc includes the following
set of components:

The MIPS-ANSI C 3.0 compiler supports a -std0 K&R1
mode with ANSI extensions, a -std1 mode which provides strict ANSI adherence, and a -std (default) mode
which is ANSI C with popular extensions.
The compiler also supports a -mips1 mode which generates code executable on any supported MIPS RISC processor (R2000, R3000 or R4000 series), and a -mips3
mode which generates code specific to and optimized
for the MIPS R4000 series processors.

• Remote Procedure Call (RPC) runtime library

• VAX C/ULTRIX
• Network Interface Definition Language (NIDL)
compiler

VAX C/ULTRIX is a K&R1 implementation of the C
programming language for all ULTRIX VAX systems.
VAX C/ULTRIX is not supported or available on ULTRIX
RISC systems.

• Local and Global Location Brokers

VAX C
/ULTRIX includes extensions as defined by the proposed ANSI Standard for C. Many compute-bound C
applications compiled with VAX C/ULTRIX will run significantly faster than when compiled with the Portable
C Compiler (pcc) on ULTRIX. VAX C/ULTRIX cannot
be used for system level programs requiring the ASM
pseudo function, or where undocumented or nonstandard C features of pcc are used. If necessary, an application can be linked using some object modules compiled with both VAX C/ULTRIX and pcc. VAX C/ULTRIX
uses the native runtime and system libraries on ULTRIX.
It also uses the native header files. It supports the pcc
command line with the exception of the following options: -go,-p,-t,-R,-S,-B. VAX C/ULTRIX is compatible
with VAX C, Version 2.3 for VMS systems, except for
VMS specific options.

DECrpc does not include other components of Apollo’s
Network Computing Architecture such as the Concurrent Programming Support or the replicated Global Location Broker.
RPC Applications are written in a high-level language
(NIDL) which in turn generates calls to the RPC runtime procedures. The stub files generated by the NIDL
compiler are C source files.
DECrpc has been tested and found compatible with the
NCS V1.5 product from Apollo.
• Network Time Protocol

• DEC C for ULTRIX

ULTRIX provides users the ability to synchronize and
distribute time for all machines in a network environment. The Network Time Protocol (NTP) is used to
synchronize time. The University of Maryland developed the NTP daemon. The University of California at
Berkeley time synchronization daemon, timed, is used
to distribute time to all machines in a network.

DEC C for ULTRIX Version 1.0 is a Digital ANSIcompliant C compiler currently available for the RISC
architecture running the ULTRIX Operating System V4.1
or later.

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

DEC C provides support for the American National Standards (ANSI) definition of the C programming language,
ANSI X3J11/88-159. DEC C has passed the Plum Hall
test suite.

CDA routines determines the structure of the documents
created by supporting applications.
CDA routines perform multiple operations including file,
stream, and aggregate management; item storage and
access; and reading, writing, and conversion of CDA
data structures. Calls to the CDA routines are encoded
within an application source file.

Using the command line options, DEC C is compatible with older dialects of C, including common (K&R1 )
C and VAX C. The compiler also provides support for
function inlining to eliminate call overhead and source
code checking features such as those found in the lint(1)
utility for assistance in identifying nonportable or unintended coding practices.

Converters bundled with the CDA Toolkit are: the
DDIF, DTIF, and Text input and output converters; a
PostScript® output converter; and an Analysis output
converter which is a debugging tool that produces text
output of CDA in-memory data structures.

In addition to the language, the ANSI C standard also
defines the contents of the C library and defining header
files.

Digital encourages independent software vendors to use
the CDA Toolkit and its converter architecture to write
new converters. The CDA Converter Architecture provides the advantage of a standard hub of interchange
so all CDA-compliant converters, whether developed by
Digital or independent software vendors, can participate
in data exchange.

The documentation for DEC C is provided in hardcopy
form and online via the Bookreader. The online man(1)
command provides access to the c89 and cpp89 manpages for the compiler and preprocessor, respectively.
The documents are provided in hardcopy form with the
Media kit and in online form on the ULTRIX Online Documentation (OLD) disc.

The CDA Viewer, also bundled with the CDA Toolkit,
displays the contents of all CDA-supported documents
on a UWS workstation or character-cell terminal.

ULTRIX and ULTRIX Worksystem Software (UWS) include a license for DEC C. The binaries and documentation are not included in the operating system media,
and must be ordered as a separate DEC C Media and
Documentation package. Refer to the SOFTWARE OPTIONS section for ordering information.

Callable DECwindows and character-cell viewer routines are used to write portable viewer widgets.
• DECthreads

• CDA Toolkit

ULTRIX includes a user-mode multi-threading capability referred to as DECthreads. DECthreads provides
an implementation of draft 4 of the proposed POSIX
1003.4a Standard. DECthreads is a library of run-time
routines callable from a C program that allows the user
to create multiple threads of execution within a single
address space. Multi-threading capability allows computation activity to be overlapped with I/O activity. Synchronization elements, such as mutexes and condition
variables, are provided to help ensure that shared resources are accessed correctly. DECthreads also provides multiple scheduling policies for scheduling and prioritizing threads.

The CDA Toolkit is an object library that provides the
data structures and routines used to create, store, and
interchange the revisable file formats supported by CDA
(Compound Document Architecture). The CDA Toolkit
is used to create CDA-compliant applications, or to write
converters that will interchange existing file formats using CDA data structures as the intermediate format.
Migration to and from the CDA environment includes
portability across the ULTRIX RISC, ULTRIX VAX and
VMS Operating Systems. Electronic mailing and copying of revisable CDA documents provide support for
hardware- and system-independent display and printing.

User Features

CDA data structures are predefined aggregate types
that store, in memory, all the items needed to encode
DDIF and DTIF documents. DDIF (Digital Data Interchange Format) aggregates are used to create CDAcompliant compound documents, graphics and image
documents, or converters. DTIF (Digital Table Interchange Format) aggregates are used to create CDAcompliant table data documents or converters for use
by spreadsheet and database applications.

User Interfaces
• Shells. ULTRIX provides the following shells:
- C Shell
- BSD™ Bourne Shell
- System V Bourne Shell
- Korn Shell

CDA data structures are used by supplying the appropriate information for all the items stored in each aggregate. The way the data structures are linked using the

All shells are programmable and allow for a tailorable
user environment.

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

• MH Mail System. MH (from RAND Corporation) is
the User Agent supplied with the ULTRIX Operating
System. A user agent is the interface with the mail
system. It provides the commands that allow the user
to send, read and handle mail, as well as determine
the form of all drafts and mail messages that are sent.

— Source programs written for the Portable C Compiler (pcc) language that follow programming
guidelines contained in Issue 2, Volume 1, Parts II
and III of System V Interface Definition are highly
compatible.
— System V Interprocess Communication (IPC)Shared Memory, Semaphores, Message Queues,
and Named Pipes.

MH can be used for sending memos and personal messages, sending files to other people, exchanging documents, forwarding messages to other people, and replying to messages that have been received.

— System V C Runtime and Math libraries are compatible.

Unlike some other systems, the user does not have to
go into a separate mail utility or program to send and
read messages. With MH, the user can type a mail command at any time. MH commands and other ULTRIX
commands may be interspersed and even combined on
one line.

Note: Under ULTRIX, source programs which conform
to the SVID, Issue 1, may require recompilation.
• Sun Network File System (NFS), Version 2.0
ULTRIX supports the Sun network services NFS, Mount,
Yellow Pages, Automount and Lock manager/Status
monitor. These services have been tested and found
compatible with the corresponding SunOS™ services
of the following Sun Operating Releases: V3.0, V3.2,
V3.4, V3.5 and V4.0. The Automounter has been tested
and found compatible with the automount service provided in SunOS Release V4.0.

• PrintServer Software. ULTRIX incorporates client
software providing support for the PrintServer range
of printers.
The software includes ANSI to
PostScript®, ReGIS to PostScript and TEK to
PostScript filters. The ReGIS to PostScript and TEK
to PostScript filters are only available on ULTRIX VAX
systems.

Named pipes accessed using NFS are not compatible
between ULTRIX-32 V3.2 and ULTRIX V4.0 systems. A
patch is available for ULTRIX-32 V3.1 systems.

Compatibility with Other UNIX® Offerings

• Commands

The ULTRIX Operating System is compatible with other
software system implementations which include:

The following ULTRIX commands meet specifications
for POSIX 1003.2, Draft 8:

• 4BSD
diff

env

find

getopts

date

mkdir

— File system formats are interchangeable provided
disk partitions are compatible.

mkfifo

chgrp

chmod

chown

— The Bourne Version 7 script shell and the C Shell
script syntax are highly compatible.

tee

join

nawk

cmp

make

basename

ULTRIX is based on the 4th Berkeley Software Distribution (4BSD), Version 4.2 and Version 4.3, and provides
the following compatibility features:

— Source code programs written for the Portable C
Compiler (pcc) and object file formats are highly
compatible.

• POSIX nawk(1)

— 4.2 BSD C Runtime and Math libraries are compatible.

In anticipation of POSIX 1003.2 final acceptance, a
POSIX convergent awk utility, now called nawk(1), is
available. nawk includes a change in the order of operator precedence. This may affect some existing awk
programs that do not explicitly define precedence with
the use of parentheses. Therefore, nawk will not replace the current awk, but will be introduced as the current awk is retired. ULTRIX 4.0 was the first release for
planning the retirement of current awk.

• SVID
ULTRIX provides SVID support based on SVID Issue 2,
Volume 1. SVID offers the following compatibility features:
— Bourne System V Shell (Issue 1) script syntax is
highly compatible.

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

The migration towards full compliancy with POSIX
1003.2 will result in the retirement of the current awk
utility when the next major release of ULTRIX becomes
available. That release will continue to deliver a version
of nawk(1) modified to reflect a POSIX 1003.2 compatible utility.

• ISO 9660
ISO 9660 is an ISO standard for a volume and file structure for the interchange of information using CDROM.
ULTRIX is based on the following levels of ISO 9660:

This implementation enables the user to:
• Mount single volume ISO 9660 formatted CDROMs as a local file system
• List and examine files using standard UNIX®
utilities and programs
• Read files and directories using the standard
POSIX system interface
— NFS export mounted ISO 9660 file systems
— Execute local and remote non-interleaved files

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

— Execute interleaved files remotely through NFS

Standard C library functions handle 8-bit characters
properly in accordance with XPG3.
The routines setlocale, strxfrm, strcoll, and strftime
are in libc. The setlocale routine allows users to select a specific instance of localization such as dictionary or telephone ordering instead of character ordering
(@modifier syntax).

Internationalization
ULTRIX Operating System includes a comprehensive
set of library routines, commands and utilities to support
the development of internationalized application software.

• Kernel

• Native Language System (NLS)

The kernel provides support for the use of Digital’s MCS
character set as well as ISO 8859/1 (e.g., 8-bit coded
character sets).

The internationalized environment is based on the definition of the NLS interface in XPG3. This includes
language support databases, an announcement mechanism (setlocale), and a message catalog system.

• Networking

The base system includes language support databases
for French, English, and German for each of three codesets: Digital’s MCS, ISO 8859/1, and ISO 646. A compiler, ic, is provided for users to define new language
support databases.

Networking commands provide full 8-bit character support. Mail is not 8-bit transparent since the U.S. government RFC 822 specifically states that the high order
bit is to be stripped. X/Open has recognized this as a
problem and will likely withdraw the requirement for 8-bit
transparent Mail.

The default locale is called the C locale and is American
English/ASCII.

DECnet is 8-bit transparent.
• Filesystem

The message catalog system includes the gencat utility
and related library functions that are used to access a
message catalog from a C language application at run
time.

The ULTRIX filesystem provides full 8-bit transparency.
Data interchange routines, such as tar and cpio, support
8-bit filenames. This can potentially cause an interoperability problem with UNIX® systems that only provide
7-bit ASCII support.

• I18N Tools
A set of tools is provided to assist engineers with the
process of extracting message text from C programs
and generating message catalogs. Message text source
files can be translated using the utility trans or with any
8-bit transparent text editor. These tools (extract, strextract, strmerge) are designed to work with the XPG3
message catalog system and are Digital enhancements
to the NLS environment.

• System Administration
Usernames with 8-bit characters are fully supported and
tools, such as adduser, have been updated to reflect
this.

Architectural Differences

• Commands and Utilities
The following differences exist between ULTRIX VAX cc
and ULTRIX RISC cc:

There are 71 8-bit transparent commands as specified
in XPG3. Several other commands are also 8-bit transparent including editors (vi, ex, ed, sed) and networking
commands (rlogin, ftp, tip, uucp).

• Hardware architectural differences exist.
• ULTRIX RISC pointers are unsigned; VAX pointers
are signed.

All NLS commands are provided and conform to the
XPG3 specification. Refer to I18N Tools.

• Cannot dereference NULL ptrs on ULTRIX RISC; includes arg to strlen.

The utility iconv provides a mechanism for codeset conversion that may be necessary in a heterogeneous network.

• asm( ) is not supported with ULTRIX RISC in any
form.

• Libraries

• MIPS-ANSI C is not avaliable on ULTRIX VAX systems.

A library of internationalization routines that conform to
XPG3 is provided (libi) as well as modifications to the
standard C library. These changes meet both the XPG3
and POSIX specifications.

• VAX C is not available on ULTRIX RISC systems.
• The MIPS R2000, R3000 and R4000 series systems
uses the COFF format (Common Object File Format)
in its object files and load modules.

ctype library routines have been modified to make use
of locale/culture specific information.

• The ULTRIX RISC compiler does not allow ‘‘oldfashioned’’ initialization. An example of this, which
works on VAX but gives a warning on ULTRIX RISC,
is: int i 0;.

-v (print commands).

• varargs is different. Any program that tries to walk
the argument list by taking the address of an argument and incrementing it will not be successful, especially for double precision arguments. Programs
using the macros in varargs.h will work. Compiling
with the -varargs option on ULTRIX RISC will attempt
to detect non-portable code.

-cpp, -nocpp: Most useful for languages other
than C.
-G: Relevant only to MIPS architecture.
-j, -k, -ko: Relevant only to ULTRIX RISC compiler
design.

• The setjmp/longjmp buffer is larger on ULTRIX RISC.
Programs with a hard-coded ten-word buffer will
fail; programs that correctly include the header file
setjmp.h and declare a jmp_buf will work correctly.

-std, -std0, -std1 (warn nonstandard usage): vcc
has -V standard=portable.

• ULTRIX RISC has boundary alignment rules. User
programs should only see this as a performance issue (the kernel does fix-ups). It is better, however, to
align double-words, words and half-words on natural
boundaries. The setsysinfo system call or uac command can be used to turn off the fixup messages.

-volatile, -varargs: Modify compiler behavior in
certain areas.
-V (print versions).

• ULTRIX RISC pointers cannot be used as the var on
switch statements.

• ULTRIX RISC has big/little endian options -EB and
-EL.

• ULTRIX RISC will not allow the same .c or .o file to
be listed twice. ULTRIX RISC will generate doubly
defined symbol errors. VAX pcc allows this.

• -unsigned indicates that variables of type char are to
be treated as unsigned quantities. The default is to
treat chars as signed.

• -L flag: On VAX pcc, -L flags on the line collectively
affect -l flags. On ULTRIX RISC, -L flags are seen
strictly left to right, so that a -l must come first.

• ULTRIX RISC recognizes the environ variables
ROOTDIR and TMPDIR.
• Profiling: On VAX, there are two levels selected with
-p and -pg. On ULTRIX RISC, there are also two
levels, selected with the -p option or by running the
post-processor program pixie(1). The ULTRIX RISC
compiler is not affected by either option; all work is
done in the assembler or loader (or postprocessor).

• ULTRIX RISC global symbols do not have an extra
leading underscore added to them. This difference
affects assembler programmers and users of nlist(3).
• The -R (read-only text) option is not yet supported
with ULTRIX RISC.
• -Md, -Mg options: Not needed on ULTRIX RISC; the
hardware has only one double precision format.

• Optimization: On ULTRIX VAX, there is one level
of optimization, off by default and enabled with -O.
On ULTRIX RISC, there are five levels. By default,
the second level is used; the -O0 option disables
this, -O or -O2 invokes global optimization. More
complex processes can be invoked with -O3 and -O4.
ULTRIX RISC also has the -Olimit switch that allows
optimization to be bypassed with overly complicated
code sections.

• ULTRIX RISC defines a macro (LANGUAGE_C, for
instance) for the preprocessor that makes it possible
to write multilingual include files.
• cpp predefined symbols: Both VAX and ULTRIX
RISC define ultrix, unix, and bsd4_2. On ULTRIX
RISC, the equivalent predefined symbol of vax is
mips. On ULTRIX RISC, MIPSEL and host_mips are
also defined.

• Selecting alternate compilers: On both architectures,
the -t and -B options specify passes and paths; however, the pass names for -t differ (there are more on
ULTRIX RISC), and the semantics of -B belong to
the -h option; -B is used to specify a command suffix instead. ULTRIX RISC also has -H, -K, and -#
arguments designed for compiler development work.

• Some ULTRIX options on the RISC R2000/R3000
/R4000 series hardware are not available on the VAX
hardware:

-I (no dirname).
-P (preprocess, produce .i file).

• Debugging information: ULTRIX RISC offers four levels, where VAX has only two (on and off).

SPD 26.40.32

Hardware Requirements

• FORTRAN and Pascal: FORTRAN and Pascal are
sold separately as layered products. Certain portions
of the unsupported code which are architecture dependent on VAX is not available on ULTRIX RISC.

The ULTRIX Operating System can execute on valid
VAX, MicroVAX or Digital RISC based systems and must
include the following minimum system configuration.
The actual amount of work supported at one time, with
good performance, depends on the types of processing
performed as well as on the physical memory and secondary storage available. (Refer to ULTRIX Worksystem Software Product Description (SPD 28.22.xx) for
minimum hardware and device hardware requirements
for all worksystems.)
• Supported ULTRIX processor at appropriate hardware revision level.
• Minimum component of main memory (refer to the
OPTIONAL HARDWARE section).
• Supported ULTRIX system device capable of holding the supported subsets (refer to the OPTIONAL
HARDWARE section).
• For local (non-network) distribution, supported ULTRIX
software load and backup device.
• A valid load device for diagnostics.
• One console terminal with ASCII capability.
• The minimum memory configuration is 6MB for VAX
and 8MB for RISC.
• Amount of memory supported is maximum supported
by hardware configurations or 512MB, whichever is
less.
• No more than ten terminal multiplexers per ULTRIX
driver type may be configured. The actual number of
terminal lines supported at one time, with good performance, depends on the types of processing performed as well as on the physical memory and CPU
type.
• LAT and DECnet traffic is restricted to one Ethernet interface/controller. Each Ethernet interface
/controller must be connected to a separate network
or subnetwork in a routing configuration. Diskless
activity requires the ability to communicate via mop.
Therefore, diskless clients are also restricted to one
Ethernet.
• TK50 media can be read but not written on a TK70
drive.
• To support an RL02 disk subsystem along with a
UDA50 DSA disk subsystem under ULTRIX, the
RL02 controller should be placed on a second
UNIBUS. When both controllers are on a single
UNIBUS the system will experience Data Lates, Hard
disk errors and sometimes file corruption.

ULTRIX/CI Support

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

ULTRIX supports configurations that utilize the Computer Interconnect (CI) hardware. A configuration can
consist of a single node or up to a maximum of 16
nodes, where a node is defined as being either an
ULTRIX supported processor or a mass storage server.
A maximum of four mass storage servers are permitted
in a CI environment. Support is provided for homogeneous CI (ULTRIX) environment only.
The mass storage server is a free-standing, high speed,
intelligent service designed to the specifications of the
Digital Storage Architecture; it is known as the Hierarchical Storage Controller (HSC).

Network Remote Installation
RIS (Remote Installation Service) performs a remote
installation through a local area network. The RIS is
structured to install remotely both VAX and RISC workstations from a VAX or RISC server. To manage a large
number of workstation installations, the RIS is capable
of installing through a database file.

The ULTRIX Operating System, Version 4.5

SPD 26.40.32

Diskless Workstations
ULTRIX supports a local area network of diskless workstations (clients) managed from a central host equipped
with the necessary mass storage (the server). Centralizing the workstation’s disk resources reduces the overall system cost and simplifies the administration of the
network.
DMS (Diskless Management Service) performs diskless
workstations setup. The DMS is structured to set up
both VAX and RISC workstations from a VAX or RISC
server. To manage a large number of diskless workstations, the DMS is capable of installing through a
database file.
The following configuration guidelines apply to diskless
workstations and servers:
• All the ULTRIX supported VAXstation and Digital
RISC worksystems are supported diskless clients.
• The minimum memory configuration is 6MB for a VAX
diskless client or 8MB for a RISC diskless client.
• The minimum memory is 16MB for a VAX diskless
server or 16MB for a RISC diskless server.
• The MicroVAX 2000, VAXstation 2000, and any
MicroVAX or VAXstation server with an RQDX1,
RQDX2, or RQDX3 disk controller is limited to the
support of three diskless clients.
• If multiple network segments are present, the DMS
clients and server must be on the same segment of
the network.
The minimum hardware requirements for any future version of this product may be different from the requirements for the current version.
Optional Hardware
Additional memory and/or secondary storage may be
required depending upon the need for ULTRIX software
or optional software products and usage of the ULTRIX
Operating System.
Note: Combinations of hardware options are subject to
limitations such as bandwidth, physical configuration restraints, thermal dissipation, and electrical loads/power.
(System configuration details are described in the VAX
Systems and Options Catalog.)
The following tables list hardware options that are supported by the ULTRIX Operating System. All device
drivers for these hardware units contained in The ULTRIX Operating System are warranted by Digital.

Notes:

Letter D = Data device only.
Letter L = Valid ULTRIX load device.

Disk and tape devices are connected to the DECsystem and DECstation via SCSI (Small Computer System Interface). There
is one integral SCSI controller. The SCSI controller will support up to seven devices in any combination. The controller has
an identifier which can be set via the DS5000 Console Interface (the factory default is id6). Each added device must have its
own unique identifier which must not conflict with any other device, including the SCSI controller. The SCSI controller should
always have the highest id.

The DECsystem 5400 and 5500 pprovide by default, a DSSI bus for RF disk support and an Ethernet interface. RF disks are
also supported by the KFQSA contoller. The DECsystem 5500 also provides by default a SCSI interface for RZ disk and TZ
tape support. RZ disks and TZ tapes are also supported on the 5500 by the KZQSA controller.

Two KZQSAs are supported on the DECsystem 5500. All SCSI disks and tapes listed in this SPD under the DECsystem
5500 are supported on the KZQSA. The KZQSA supports data devices only and not boot devices.

Although there are 4 ports, ports 1 and 2 are not available. Port 3 is a system console. Port 4 is available for printer or
modem.

The modems must be configured such that the Forced DSR attribute is NOT set on the modem. If the Forced DSR attribute
is set, the modem will be unable to recognize loss of connection, and may incorrectly assume that a connection has been
established. Consult the modem’s Owner’s Manual for specific information on clearing the Forced DSR option.

DEClaser support is equivalent to that which is available for the LN03, LN03R, and LN03S printers.

Accepts TK50 distribution media.

Automatic stack loader tape drives are supported only by the dump, restore and cpio system utilities.

Although there are four ports, ports 1 and 2 are not available. Port 3 is system console. Port 4 is available for printer or
modem.

The SCSI (Small Computer System Interface) cable length is limited to six meters, thereby limiting the number of external
devices (tapes and disk) that can actually be attached to the system per bus.

Disk and tape devices are connected to the DECsystem and DECstation via SCSI (Small Computer System Interface). There
is one integral SCSI controller and, optionally, up to three more SCSI controllers may be added. Each SCSI controller will
support up to seven devices in any combination. Each controller has an identifier which can be set via the DS5000 Console
Interface (the factory default is id6). Each added device must have its own unique identifier which must not conflict with any
other device on its bus including the SCSI controller. The SCSI controller should always have the highest id.

On the DECsytem 5000 Model 25/33/50, the RX26 device may either be FDI-based, in which case it is integral in the system;
or SCSI-based, in which case it is a separate device. On the DECsystem 5900, the RX26 is SCSI-based.

The DECsystem 5000 Model 25/33/50 has one general purpose asynchronous/synchronous serial interface on the system
module. A TURBOchannel-based serial connector would be needed if more serial lines are required.

DEClaser support is equivalent to that which is available for the LN03, LN03R, and LN03S printers.

The RZ23, RZ23L, RZ24 and RZ24L devices are supported via the TURBOchannel Extender (TcE) box.

Disks and tapes supported on the CITCA are those CI devices already supported on the DECsystem 5800 series platforms,
e.g. ESE20, TAxx tapes, RAxx disks and HSCxx controllers. Devices connected to CITCA are supported as data devices
only.

Accepts TK50 distribution media.

Automatic stack loader tape drives are supported only by the dump, restore and cpio system utilities.
