UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis (now Xinuos). UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system. [1] [2]

History

Univel (1991–1993)

After the SVR4 effort to merge SunOS and System V, AT&T's Unix System Laboratories (USL) formed the Univel partnership with Novell to develop a desktop version of Unix for i386 and i486 machines, codenamed "Destiny". [3]

Destiny is based on the Unix System V release 4.2 kernel. The MoOLIT toolkit is used for the windowing system, allowing the user to choose between an OPEN LOOK or MOTIF-like look and feel at runtime. In order to make the system more robust on commodity desktop hardware, the Veritas VXFS journaling file system is used in place of the UFS file system used in SVR4. Networking support in UnixWare includes both TCP/IP and interoperability with Novell's NetWare protocols (IPX/SPX); the former were the standard among Unix users at the time of development, while PC networking was much more commonly based on NetWare. [4]

Destiny was released in 1992 as UnixWare 1.0, with the intention of unifying the fragmented PC Unix market behind this single variant of the operating system. The system was earlier to reach the corporate computing market than Microsoft's Windows NT, but observers of the period remarked that UnixWare was "just another flavor of Unix", Novell's involvement being more a marketing ploy than a significant influx of technology. [4] There two editions of Destiny: a Personal Edition, which includes Novell IPX networking but not TCP/IP, and an Advanced Server Edition with TCP/IP and other server software. The personal edition is limited to two active users, while the server edition includes an unlimited user license. Around 35,000 copies of UnixWare 1.0 were sold. [5]

In 1992, UnixWare 1.0 Personal Edition came with DOS Merge 3.0 and Novell's DR DOS 6.0.

In 1993, Novell purchased USL from AT&T and merged USL and Univel into a new Unix Systems Group. [6]

Novell (1993–1995)

In 1994 Novell released UnixWare 1.1, which includes TCP/IP in both the personal and advanced server editions. [7] The MOTIF 1.2 runtime libraries are included for COSE compliance. NUC (NetWare Unix Client) software is included for integration with Novell NetWare servers. The Advanced Merge application is installed on both the server and personal editions to allow running DOS and Windows 3.1 applications.

Novell later released bug-fix versions 1.1.1, 1.1.2, 1.1.3 and finally 1.1.4 on 19 June 1995. [8]

UnixWare 2.0, based on the Unix System V release 4.2MP kernel, which added support for multiprocessing, began shipping to OEMs and developers in December 1994, [9] and to the consumer market in March 1995. [10] Both the personal and server editions support two processor systems, with the possibility of buying extra Processor Upgrade licenses for the server edition. Supported multiprocessor systems include standard Intel MP 1.1 SMP machines and Corollary C-bus systems. The system supports NetWare ODI network drivers in an effort to increase the number of supported network interfaces. Other new features in the release include a POSIX Threads library in addition to the older UI threads library. [9]

Before SCO licensed UnixWare in 1995, Novell had also announced a project to create a "SuperNOS" based on NetWare 4.1 and UnixWare 2.0 technologies in the future. This never materialized. Instead, a NetWare 4.10 server on Linux was offered as Caldera NetWare for Linux for OpenLinux since 1998, and Novell's Open Enterprise Server finally came in 2005.

Santa Cruz Operation (1995–2001)

At the tail end of Novell's ownership of UnixWare, the company celebrated project completion of "Eiger", the codename for UnixWare 2.1 Novell UnixWare 2.1 Eiger Project Completion 1995 commemorative pen and case.jpg

In 1995, the Santa Cruz Operation (SCO) acquired UnixWare from Novell. [11] The exact terms of this transaction were disputed (see SCO vs Novell); courts have subsequently determined that Novell retained the ownership of Unix.

When the transfer was made public SCO announced that it would work towards merging UnixWare with its OpenServer SVR3.2 based OS, [12] but the first release of UnixWare from SCO was version 2.1 in 1996. At the release of UnixWare 2.1 it was announced that the proposed UnixWare/OpenServer merger was known as project Gemini, to be available in 1997 and a 64-bit version of UnixWare was to be developed for 1998. [13]

One controversial change was the adoption of an OpenServer-like user licensing policy. The Univel and Novell releases of UnixWare allow 2 users on the personal edition or unlimited numbers of users on the server edition. With UnixWare 2.1 the server edition includes a license for up to 5 users. Customers wanting more users could purchase 10, 25, 100, 500 or unlimited user license extensions. [14]

SCO released three updates to UnixWare 2.1. UnixWare 2.1.1, released in 1996 achieved Unix 95 branding. [15] UnixWare 2.1.2 and 2.1.3, available in 1998, are largely bug fix releases.

In 1998 Compaq released a package known as the Integrity XC consisting of a single-system image cluster of Proliant servers with a version of UnixWare 2.1, UnixWare NonStop Clusters. [16]

The first results of the Gemini project were made available in early 1998 as UnixWare 7. [17] SCO named the kernel version Unix System V release 5. The system is largely based on UnixWare 2.1, with features for driver compatibility with OpenServer, allowing use of OpenServer network drivers. System administration utilities from OpenServer, scoadmin, replace the original UnixWare sysadm utility. Major new features of UnixWare 7 include multi-path I/O, large files and file systems and support for large memory systems. [18]

UnixWare 7 lacks the Xenix compatibility features of both its ancestors.[ citation needed ]

In 1999 SCO released the UnixWare 7.1 update which increased the number of editions; the Business (5-user), Department (25 user) and Enterprise (50 user) editions replace the earlier personal and server editions. The WebTop application from Tarantella, Inc. is included. [19]

In 2000 SCO released the UnixWare 7.1.1 update. Simultaneously the UnixWare NonStop Clusters 7.1.1+IP single-system image cluster package was released. This new package allows commodity hardware to be used as well as the proprietary Compaq hardware supported by the earlier Integrity XC product, and was directly available from SCO. [20]

Caldera Systems, Caldera International and The SCO Group (2000–2011)

On 2 August 2000,[ citation needed ] Santa Cruz Operation (SCO) announced that it would sell its Server Software and Services Divisions, as well as rights to the OpenServer and UnixWare products, to Caldera Systems. In March 2001, Caldera Systems became Caldera International (CII), and the SCO purchase was completed in May 2001.[ citation needed ] The remaining part of the Santa Cruz Operation company, the Tarantella Division, changed its name to Tarantella, Inc.

Caldera International's initial release of UnixWare was renamed OpenUNIX 8. This release is what would have been UnixWare 7.1.2.

Caldera International renamed itself to The SCO Group in August 2002, after broadening its product line to include mobile products and services.

Later, the newly renamed The SCO Group reverted to the previous UnixWare brand and version release numbering, releasing UnixWare 7.1.3 [21] and 7.1.4. [22] No further OpenUNIX releases were made available and OpenUNIX 8.1.2 (OU812)[ citation needed ] was never released. The SCO Group continued to maintain UnixWare and issues periodic maintenance updates and support. [23]

Between 2007 and 2011, The SCO Group engaged in a series of legal battles. In September 2007, The SCO Group filed for Chapter 11 bankruptcy protection. [24]

On 11 April 2011, UnXis bought The SCO Group operating assets and intellectual property rights after having been approved by the bankruptcy court in Delaware. [25] [26]

The SCO Group, Inc. then renamed itself TSG Group, Inc., and SCO Operations, Inc. became TSG Operations, Inc., [27] and in August 2012 filed to convert from Chapter 11 to Chapter 7. [28]

UnXis and Xinuos (2011–present)

The rights to Unixware, as well as OpenServer, were acquired by UnXis in 2011.

In June 2013 UnXis was renamed as Xinuos [29] and announced product and availability for SCO UnixWare 7.1.4+, [30] now supporting both physical and virtual machines.

SCO Group, Inc. v. International Business Machines Corp., commonly abbreviated as SCO v. IBM, is a civil lawsuit in the United States District Court of Utah. The SCO Group asserted that there are legal uncertainties regarding the use of the Linux operating system due to alleged violations of IBM's Unix licenses in the development of Linux code at IBM. The lawsuit was filed in 2003, it has lingered on through the bankruptcy of SCO Group and the adverse result in SCO v. Novell, and was reopened for continued litigation by order of a new judge on June 14, 2013. Pursuant to the court order reopening the case, an IBM Motion for Summary Judgment was filed based upon the results of the Novell decision. On December 15, 2014, the judge granted most of IBM's motion, thereby narrowing the scope of the case, which remained open. On March 1, 2016, following a ruling against the last remaining claims, the judge dismissed SCO's suit against IBM with prejudice. SCO filed an appeal later that month. In February 2018, as a result of the appeal and the case being partially remanded to the circuit court, the parties restated their remaining claims and provided a plan to move toward final judgement.

Unix System Laboratories (USL), sometimes written UNIX System Laboratories to follow relevant trademark guidelines of the time, was an American software laboratory and product development company that existed from 1989 through 1993. At first wholly, and then majority, owned by AT&T, it was responsible for the development and maintenance of one of the main branches of the Unix operating system, the UNIX System V Release 4 source code product. Through Univel, a partnership with Novell, it was also responsible for the development and production of the UnixWare packaged operating system for Intel architecture. In addition it developed Tuxedo, a transaction processing monitor, and was responsible for certain products related to the C++ programming language. USL was based in Summit, New Jersey, and its CEOs were Larry Dooling followed by Roel Pieper.

In a series of legal disputes between SCO Group and Linux vendors and users, SCO alleged that its license agreements with IBM meant that source code IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the Linux community disagreed with SCO's claims; IBM, Novell, and Red Hat filed claims against SCO.

<i>SCO Group, Inc. v. Novell, Inc.</i>

SCO v. Novell was a United States lawsuit in which the software company The SCO Group (SCO), claimed ownership of the source code for the Unix operating system. SCO sought to have the court declare that SCO owned the rights to the Unix code, including the copyrights, and that Novell had committed slander of title by asserting a rival claim to ownership of the Unix copyrights. Separately, SCO was attempting to collect license fees from Linux end-users for Unix code through their SCOsource division, and Novell's rival ownership claim was a direct challenge to this initiative. Novell had been increasing their investments in and support of Linux at this time, and was opposed to SCO's attempts to collect license fees from Novell's potential customers.

Beginning in 2003, The SCO Group was involved in a dispute with various Linux vendors and users. SCO initiated a series of lawsuits, the most known of which were SCO v. IBM and SCO v. Novell, that had implications upon the futures of both Linux and Unix. SCO claimed that Linux violated some of SCO's intellectual properties. Many industry observers were skeptical of SCO's claims, and they were strongly contested by SCO's opponents in the lawsuits, some of which launched counter-claims. By 2011, the lawsuits fully related to Linux had been lost by SCO or rendered moot and SCO had gone into bankruptcy. However the SCO v. IBM suit continued for another decade, as it included contractual disputes related to both companies' involvement in Project Monterey in addition Linux-related claims. Finally in 2021 a settlement was reached in which IBM paid the bankruptcy trustee representing what remained of SCO the sum of $14.25 million.

<span class="mw-page-title-main">History of Unix</span>

The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. Multics introduced many innovations, but also had many problems. Bell Labs, frustrated by the size and complexity of Multics but not its aims, slowly pulled out of the project. Their last researchers to leave Multics – among them Ken Thompson, Dennis Ritchie, Doug McIlroy, and Joe Ossanna – decided to redo the work, but on a much smaller scale.

Univel existed only briefly in the period between AT&T initially divesting parts of USL in 1991, and its eventual outright purchase by Novell, which completed in June 1993, thereby acquiring rights to the Unix operating system. Novell merged USL and Univel into their new Unix Systems Group (USG).

Caldera OpenLinux (COL) is a defunct Linux distribution. Caldera originally introduced it in 1997 based on the German LST Power Linux distribution, and then taken over and further developed by Caldera Systems since 1998. A successor to the Caldera Network Desktop put together by Caldera since 1995, OpenLinux was an early "business-oriented distribution" and foreshadowed the direction of developments that came to most other distributions and the Linux community generally.

3DA was an alliance formed between The Santa Cruz Operation (SCO) and Hewlett-Packard (HP) in September 1995. Its purpose was to unify SCO's OpenServer product, UnixWare, and HP-UX from HP; the resulting product would then become the de facto Unix standard for both existing x86 systems and the upcoming IA-64 processor architecture from Intel.

<span class="mw-page-title-main">SCO Forum</span> Unix conference

SCO Forum was a technical computer conference sponsored by the Santa Cruz Operation (SCO), briefly by Caldera International, and later The SCO Group that took place during the 1980s through 2000s. It was held annually, most often in August of each year, and typically lasted for much of a week. From 1987 through 2001 it was held in Santa Cruz, California, on the campus of the University of California, Santa Cruz. The scenic location, amongst redwood trees and overlooking Monterey Bay, was considered one of the major features of the conference. From 2002 through 2008 it was held in Las Vegas, Nevada, at one of several hotels on the Las Vegas Strip. Despite the name and location changes, the conference was considered to be the same entity, with both the company and attendees including all instances in their counts of how many ones they had been to.
