Solaris is a Unix operating system originally developed by Sun Microsystems. It superseded their earlier SunOS in 1993. Oracle Solaris, so named as of 2010, has been owned by Oracle Corporation since the Sun acquisition by Oracle in January 2010.
Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. Solaris supports SPARC-based and x86-based workstations and servers from Oracle and other vendors, with efforts underway to port to additional platforms. Solaris is registered as compliant with the Single Unix Specification.
Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open source project. With OpenSolaris, Sun wanted to build a developer and user community around the software. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. In August 2010, Oracle discontinued providing public updates to the source code of the Solaris kernel, effectively turning Solaris 11 into a closed source proprietary operating system. Following that, in 2011 the Solaris 11 kernel source code leaked to BitTorrent. However, through the Oracle Technology Network (OTN), industry partners can still gain access to the in-development Solaris source code. Source code for the open source components of Solaris 11 is available for download from Oracle.
In 1987, AT&T Corporation and Sun announced that they were collaborating on a project to merge the most popular Unix variants on the market at that time: BSD, System V, and Xenix. This became Unix System V Release 4 (SVR4).
On September 4, 1991, Sun announced that it would replace its existing BSD-derived Unix, SunOS 4, with one based on SVR4. This was identified internally as SunOS 5, but a new marketing name was introduced at the same time: Solaris 2. Although SunOS 4.1.x micro releases were retroactively named Solaris 1 by Sun, the Solaris name is used almost exclusively to refer to the SVR4-derived SunOS 5.0 and later.
The justification for this new overbrand was that it encompassed not only SunOS, but also the OpenWindows graphical user interface and Open Network Computing (ONC) functionality. The SunOS minor version is included in the Solaris release number. For example, Solaris 2.4 incorporated SunOS 5.4. After Solaris 2.6, Sun dropped the 2. from the number, so Solaris 7 incorporates SunOS 5.7, and the latest release SunOS 5.11 forms the core of Solaris 11.3.
Solaris originated on the SPARC. The first x86 port, of version 2.1, was originally intended by Sun as a desktop operating system for large businesses that would also use Solaris on their high-end server machines. It included the Wabi emulator to support Microsoft Windows applications. For smaller clients, Sun simultaneously maintained the Interactive Unix system that it had acquired from Interactive Systems Corporation.
Solaris has a reputation for being well-suited to symmetric multiprocessing, supporting a large number of CPUs. It has historically been tightly integrated with Sun's SPARC hardware (including support for 64-bit SPARC applications since Solaris 7), with which it is marketed as a combined package. This has led to more reliable systems, but at a cost premium compared to commodity PC hardware. However, it has supported x86 systems since Solaris 2.1 and 64-bit x86 applications since Solaris 10, allowing Sun to capitalize on the availability of commodity 64-bit CPUs based on the x86-64 architecture. Sun has heavily marketed Solaris for use with both its own "x64" workstations and servers based on AMD Opteron and Intel Xeon processors, as well as x86 systems manufactured by companies such as Dell, Hewlett-Packard, and IBM. As of 2009, the following vendors support Solaris for their x86 server systems:
- Dell – will "test, certify, and optimize Solaris and OpenSolaris on its rack and blade servers and offer them as one of several choices in the overall Dell software menu"
- IBM – also distributes Solaris and Solaris Subscriptions for select x86-based IBM System x servers and BladeCenter servers
- Hewlett-Packard – distributes and provides software technical support for Solaris on ProLiant server and blade systems
- Fujitsu Siemens
As of July 2010, Dell and HP certify and resell Oracle Solaris, Oracle Enterprise Linux and Oracle VM on their respective x86 platforms, and IBM stopped direct support for Solaris on x64 kit.
Solaris 2.5.1 included support for the PowerPC platform (PowerPC Reference Platform), but the port was canceled before the Solaris 2.6 release. In January 2006, a community of developers at Blastwave began work on a PowerPC port which they named Polaris. In October 2006, an OpenSolaris community project based on the Blastwave efforts and Sun Labs' Project Pulsar, which re-integrated the relevant parts from Solaris 2.5.1 into OpenSolaris, announced its first official source code release.
On November 28, 2007, IBM, Sun, and Sine Nomine Associates demonstrated a preview of OpenSolaris for System z running on an IBM System z mainframe under z/VM, called Sirius (in analogy to the Polaris project, and also due to the primary developer's Australian nationality: HMS Sirius of 1786 was a ship of the First Fleet to Australia). On October 17, 2008, a prototype release of Sirius was made available and on November 19 the same year, IBM authorized the use of Sirius on System z Integrated Facility for Linux (IFL) processors.
Solaris also supports the Linux platform application binary interface (ABI), allowing Solaris to run native Linux binaries on x86 systems. This feature is called Solaris Containers for Linux Applications (SCLA), based on the branded zones functionality introduced in Solaris 10 8/07.
Installation and usage options
Solaris can be installed from various pre-packaged software groups, ranging from a minimalistic Reduced Network Support to a complete Entire Plus OEM. Installation of Solaris is not necessary for an individual to use the system. Additional software, like Apache, MySQL, etc. can be installed as well in a packaged form from sunfreeware and OpenCSW. Solaris can be installed from physical media or a network for use on a desktop or server, or be without installing on a desktop or server.
Early releases of Solaris used OpenWindows as the standard desktop environment. In Solaris 2.0 to 2.2, OpenWindows supported both NeWS and X applications, and provided backward compatibility for SunView applications from Sun's older desktop environment. NeWS allowed applications to be built in an object-oriented way using PostScript, a common printing language released in 1982. The X Window System originated from MIT's Project Athena in 1984 and allowed for the display of an application to be disconnected from the machine where the application was running, separated by a network connection. Sun’s original bundled SunView application suite was ported to X.
Sun later dropped support for legacy SunView applications and NeWS with OpenWindows 3.3, which shipped with Solaris 2.3, and switched to X11R5 with Display Postscript support. The graphical look and feel remained based upon OPEN LOOK. OpenWindows 3.6.2 was the last release under Solaris 8. The OPEN LOOK Window Manager (olwm) with other OPEN LOOK specific applications were dropped in Solaris 9, but support libraries were still bundled, providing long term binary backwards compatibility with existing applications. The OPEN LOOK Virtual Window Manager (olvwm) can still be downloaded for Solaris from sunfreeware and works on releases as recent as Solaris 10.
Sun and other Unix vendors created an industry alliance to standardize Unix desktops. As a member of the Common Open Software Environment (COSE) initiative, Sun helped co-develop the Common Desktop Environment (CDE). This was an initiative to create a standard Unix desktop environment. Each vendor contributed different components: Hewlett-Packard contributed the window manager, IBM provided the file manager, and Sun provided the e-mail and calendar facilities as well as drag-and-drop support (ToolTalk). This new desktop environment was based upon the Motif look and feel and the old OPEN LOOK desktop environment was considered legacy. CDE unified Unix desktops across multiple open system vendors. CDE was available as an unbundled add-on for Solaris 2.4 and 2.5, and was included in Solaris 2.6 through 10. In 2001, Sun issued a preview release of the open-source desktop environment GNOME 1.4, based on the GTK+ toolkit, for Solaris 8. Solaris 9 8/03 introduced GNOME 2.0 as an alternative to CDE. Solaris 10 includes Sun's Java Desktop System (JDS), which is based on GNOME and comes with a large set of applications, including StarOffice, Sun's office suite. Sun describes JDS as a "major component" of Solaris 10. The Java Desktop System is not included in Solaris 11 which instead ships with a stock version of GNOME. Likewise, CDE applications are no longer included in Solaris 11, but many libraries remain for binary backwards compatibility.
From 2005–10, when Solaris was still being developed by Sun Microsystems, Solaris' source code (with a few exceptions) was released under the Common Development and Distribution License (CDDL) via the OpenSolaris project.
When Sun was acquired by Oracle in 2010, the OpenSolaris project was discontinued after the board became unhappy with Oracle's stance on the project. In March 2010, the previously freely available Solaris 10 was placed under a restrictive license that limited the use, modification and redistribution of the operating system. The license allowed the user to download the operating system free of charge, through the Oracle Technology Network, and use it for a 90-day trial period. After that trial period had expired the user would then have to purchase a support contract from Oracle to continue using the operating system.
With the release of Solaris 11 in 2011, the license terms changed again. The new license allows Solaris 10 and Solaris 11 to be downloaded free of charge from the Oracle Technology Network and used without a support contract indefinitely however the license only expressly permits the user to use Solaris as a development platform and expressly forbids commercial and "production" use. Educational use is permitted in some circumstances. From the OTN license:
If You are an educational institution vested with the power to confer official high school, associate, bachelor, master and/or doctorate degrees, or local equivalent, (“Degree(s)”), You may also use the Programs as part of Your educational curriculum for students enrolled in Your Degree program(s) solely as required for the conferral of such Degree (collectively “Educational Use”).
When Solaris is used without a support contract it can be upgraded to each new "point release" however a support contract is required for access to patches and updates that are released monthly.
Updates to Solaris versions are periodically released, such as Solaris 10 1/13 ("U11").

The underlying Solaris codebase has been under continuous development since work began in the late 1980s on what was eventually released as Solaris 2.0. Each version such as Solaris 10 is based on a snapshot of this development codebase, taken near the time of its release, which is then maintained as a derived project. Updates to that project are built and delivered several times a year until the next official release comes out.
In 2003, an addition to the Solaris development process was initiated. Under the program name Software Express for Solaris (or just Solaris Express), a binary release based on the current development basis was made available for download on a monthly basis, allowing anyone to try out new features and test the quality and stability of the OS as it progressed to the release of the next official Solaris version. A later change to this program introduced a quarterly release model with support available, renamed Solaris Express Developer Edition (SXDE).
In 2007, Sun announced Project Indiana with several goals, including providing an open source binary distribution of the OpenSolaris project, replacing SXDE. The first release of this distribution was OpenSolaris 2008.05.
The Solaris Express Community Edition (SXCE) was intended specifically for OpenSolaris developers. It was updated every two weeks until it was discontinued in January 2010, with a recommendation that users migrate to the OpenSolaris distribution. Although the download license seen when downloading the image files indicates its use is limited to personal, educational and evaluation purposes, the license acceptance form displayed when the user actually installs from these images lists additional uses including commercial and production environments.
SXCE releases terminated with build 130 and OpenSolaris releases terminated with build 134 a few weeks later. The next release of OpenSolaris based on build 134 was due in March 2010, but it was never fully released, though the packages were made available on the package repository. Instead, Oracle renamed the binary distribution Solaris 11 Express, changed the license terms and released build 151a as 2010.11 in November 2010.
Open source derivatives
- Illumos – A fully open source fork of the project, started in 2010 by a community of Sun OpenSolaris engineers and the NexentaOS support. Note that OpenSolaris was not 100% open source: Some drivers and some libraries were property of other companies that Sun (now Oracle) licensed and was not able to release.
- OpenIndiana – A project under the illumos umbrella aiming "... to become the defacto OpenSolaris distribution installed on production servers where security and bug fixes are required free of charge."
- SchilliX – The first LiveCD released after OpenSolaris code was opened to public.
- MartUX – The first SPARC distribution of OpenSolaris, with an alpha prototype released by Martin Bochnig in April 2006. It was distributed as a Live CD but is later available only on DVD as it has had the Blastwave community software added. Its goal was to become a desktop operating system. The first SPARC release was a small Live CD, released as marTux_0.2 Live CD in summer of 2006, the first straight OpenSolaris distribution for SPARC (not to be confused with GNOME metacity theme). It was later re-branded as MartUX and the next releases included full SPARC installers in addition to the Live media. Much later, MartUX was re-branded as OpenSXCE when it moved to the first OpenSolaris release to support both SPARC and Intel architectures after Sun was acquired by Oracle.
- MilaX – A small Live CD/Live USB with minimal set of packages to fit a 90 MB image.
- EON ZFS Storage – A NAS implementation targeted at embedded systems.
- Jaris OS – Live DVD and also installable. Pronounced according to the IPA but in English as Yah-Rees. This distribution has been heavily modified to fully support a version of Wine called Madoris that can install and run Windows programs at native speed. Jaris stands for "Japanese Solaris". Madoris is a combination of the Japanese word for Windows "mado" and Solaris.
- napp-it – A webmanaged ZFS storage appliance based on Solaris and the free forks like OmniOS with a Free and Pro edition.
- OpenSXCE – An OpenSolaris distribution release for both 32-bit and 64-bit x86 platforms and SPARC microprocessors, initially produced from OpenSolaris source code repository, ported to the illumos source code repository to form OpenIndiana's first SPARC distribution. Notably, the first OpenSolaris distribution with illumos source for SPARC based upon OpenIndiana, OpenSXCE finally moved to a new source code repository, based upon DilOS, where new releases continue.
- NexentaStor – Optimized for storage workloads, based on Nexenta OS.
- Dyson – illumos kernel with GNU userland and packages from Debian. Strives to become an official Debian port.
- SmartOS – Virtualization centered derivative from Joyent.
- OpenSolaris – A project initiated by Sun Microsystems, discontinued after the acquisition by Oracle.
- Nexenta OS (discontinued October 31, 2012) – First distribution based on Ubuntu userland with Solaris-derived kernel.
- StormOS (discontinued September 14th, 2012) – A lightweight desktop OS based on Nexenta OS and Xfce.

Neither Microsoft Windows nor Linux can match Solaris in this type of high-end architecture, said Tony Iams, an analyst at Port Chester, N.Y., research company D.H. Brown and Associates. "Solaris has earned its reputation over a long period of time," Iams said. "They have been working on high-end scalability features for 10 years, and that's the only way you can get solid results."
