PRODUCT NAME: The ULTRIX Operating System, Version 4.5 SPD 26.40.32

Description

The ULTRIX Operating System, Version 4.5 is Digi-

tal Equipment Corporation’s native implementation of

the UNIX® Operating System for all currently sup-

ported VAX, MicroVAX, VAXstation, VAXserver and Dig-

ital 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 hi-

erarchy 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. POSIX-

compatible 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.

ULTRIX supports synchronous ﬁle system writes on a

per-ﬁle basis. In addition, an option to the ‘‘mount’’ com-

mand 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

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 en-

hancements and System V™ memory extensions. It

provides full demand paging for both ﬁles resident on a

local ﬁle system and ﬁles remotely resident and acces-

sible 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. Sys-

tem V features include demand paged shared memory

support and page locking.

The ULTRIX virtual memory programmer’s interface pro-

vides full source level compliance to existing standards.

New interfaces of SVID issue 3 are not currently sup-

ported.

Multiprocessor Support

The ULTRIX kernel has been enhanced to support mul-

tiple processors executing kernel code. Support has

been added for both RISC and VAX multiprocessor sys-

tems. Semaphores and spin locks synchronize access

to kernel data structures. Each processor shares a com-

mon 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 RISC includes OPEN SCSI CAM, a new soft-

ware 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 proces-

sor. With this well architectured interface, system manu-

facturers, system integrators, controller manufacturers,

Software Product Description 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.
PAGE 2
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.
PAGE 3
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.
PAGE 4
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.
PAGE 5
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.
PAGE 6
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.
PAGE 7
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.
PAGE 8
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).
PAGE 9
The ULTRIX Operating System, Version 4.5 SPD 26.40.32 -W (phase, opt). • 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.
PAGE 10
The ULTRIX Operating System, Version 4.5 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.
PAGE 11
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.
PAGE 12
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.
