Solaris is a UNIX-based operating system introduced by Sun Microsystems in 1992 as the successor to SunOS.

Solaris is known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace and ZFS.[1][2] Solaris supports SPARC-based and x86-based workstations and servers from Sun and other vendors, with efforts underway to port to additional platforms.

Solaris is certified against the Single Unix Specification. Although it was historically developed as proprietary software, it is supported on systems manufactured by all major server vendors, and the majority of its codebase is now open source software via the OpenSolaris project.

[edit] History

In 1987, AT&T 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 would become Unix System V Release 4 (SVR4).[3]

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.[4] While SunOS 4.1.x micro releases were retroactively named Solaris 1 by Sun, the Solaris name is almost exclusively used to refer to the SVR4-derived SunOS 5.0 and later.[5]

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 5.10 forms the core of Solaris 10.

[edit] Supported architectures

Solaris uses a common code base for the platforms it supports: SPARC and i86pc (which includes both x86 and x86-64).[6]

Solaris has a reputation for being well-suited to symmetric multiprocessing, supporting a large number of CPUs.[7] 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 often led to more reliable systems, but at a cost premium over commodity PC hardware. However, it has also supported x86 systems since Solaris 2.1 and the latest version, Solaris 10, includes support for 64-bit x86 applications, 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"[8]
  • IBM - also distributes Solaris and Solaris Subscriptions for select x86-based IBM System x servers and BladeCenter servers[9]
  • Intel[10]
  • Hewlett-Packard[11] - distributes and provides software technical support for Solaris on ProLiant server and blade systems
  • Fujitsu Siemens[12]

[edit] Other platforms

Solaris 2.5.1 included support for the PowerPC platform (PowerPC Reference Platform), but the port was canceled almost as soon as it was released. In January 2006 a community of developers at Blastwave began work on a PowerPC port which they named Polaris.[13] In October 2006, an OpenSolaris community project called Polaris was begun within the OpenSolaris project based on the Blastwave efforts.[14] and kickstarted by Sun Labs' Project Pulsar[15], integrating the relevant parts from Solaris 2.5.1 into OpenSolaris[16]. The project showed great success largely due to the continual efforts of Tom Riddle ( Sun ), Guy Shaw ( Sun ) and Dennis Clake ( Blastwave ) and in 31 May 2006 the Blastwave project revealed the Initial Polaris kernel.[17].

A port of Solaris to the Intel Itanium architecture was announced in 1997 but never brought to market.[18]

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[19], 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[20] and on November 19 the same year, IBM authorized the use of Sirius on System z IFL processors.[21]

Solaris also supports the Linux platform ABI, allowing Solaris to run native Linux binaries on x86 systems. This feature is called "Solaris Containers for Linux Applications" or SCLA, based on the branded zones functionality introduced in Solaris 10 8/07.[22]

[edit] Installation and usage options

Solaris 10 packaging groups

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.

[edit] Usage with installation

Solaris 10 text installation
Solaris 10 graphical installation

Solaris can be installed from physical media or a network for use on a desktop or server.

Solaris can be interactively installed from a text console on platforms without a video display and mouse. This may be selected for servers, in a rack, in a remote data center, from a terminal server or even dial up modem.

Solaris can be interactively installed from a graphical console. This may be selected for personal workstations or laptops, in a local area, where a console may normally be used.

Solaris can be automatically installed over a network. System administrators can customize installations with scripts and configuration files, including configuration and automatic installation of third-party software, without purchasing additional software management utilities.

When Solaris is installed, the operating system will reside on the same system where the installation occurred. Applications may be individually installed on the local system, or can be mounted via the network from a remote system.

[edit] Usage without installation

Solaris can be used without separately installing the operating system on a desktop or server.

Solaris can be booted from a remote server providing an OS image in a diskless environment, or in an environment where an internal disk is only used for swap space. In this configuration, the operating system still runs locally on the system. Applications may or may not reside locally when they are running. This may be selected for businesses or educational institutions where rapid setup is required (workstations can be "rolled off" of a loading dock, the MAC address registered into a central server, the workstation plugged in, and users can immediately leverage the desktop) or rapid replacement is required (if a desktop hardware failure occurs, a new workstation is pulled from a closet, plugged in, and a user can resume their work from their last saved point.)

Solaris can be used from an X terminal, which can boot from embedded or network accessible firmware and display a desktop immediately to the user. Applications and the operating system run remotely on one or more servers, but the graphical rendering (and occasionally the window manager) is offloaded to the X terminal. In the case of a desktop hardware failure, an X terminal can be easily replaced, and a user can resume their work from their last saved point.

Solaris can also be used from a thin client. Applications, operating system, window manager, and graphical rendering runs on one or more remote servers. Administrators can add a user account to a central Solaris system and a thin client can be rolled from a closet, placed on a desktop, and a user can start work immediately. If there is a hardware failure, the thin client can be swapped and the user can resume their work from the exact point of failure, whether or not the work was saved.

[edit] Desktop environments

olvwm with OpenWindows on Solaris

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.

Common Desktop Environment

Sun and other Unix vendors created an industry alliance to standardize Unix desktops. As a member of COSE, the Common Open Software Environment initiative, Sun helped co-develop the Common Desktop Environment. CDE 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. Solaris 2.5 onwards supported CDE. CDE unified Unix desktops across multiple open system vendors.

GNOME Version 2.24

In 2001, Sun issued a preview release of the open-source desktop environment GNOME 1.4, based on the GTK+ toolkit, for Solaris 8.[23] Solaris 9 8/03 introduced GNOME 2.0 as an alternative to CDE. Solaris 10 includes Sun's Java Desktop System, 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.[24]

The open source desktop environments KDE and XFCE, along with numerous other window managers, also compile and run on recent versions of Solaris.

Sun was investing in a new desktop environment called Project Looking Glass since 2003. The environment has been copied by other desktop vendors.

[edit] License

Solaris' source code (with a few exceptions) has been released under the Common Development and Distribution License (CDDL) via the OpenSolaris project.[25] The CDDL is an OSI-approved license.[26] It is considered by the Free Software Foundation to be free but incompatible with the GPL.[27]

OpenSolaris was seeded on June 14, 2005 from the then-current Solaris development code base; both binary and source versions are currently downloadable and licensed without cost. Source for upcoming features such as Xen support is now added to the OpenSolaris project as a matter of course, and Sun has said that future releases of Solaris proper will henceforth be derived from OpenSolaris.[28]

A more comprehensive summary of some Solaris versions is also available.[43] Solaris releases are also described in the Solaris 2 FAQ.[44]

[edit] Development release

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.

The Solaris version under development by Sun as of 2008 is codenamed Nevada, and is derived from what is now the OpenSolaris codebase.

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.[45] A later change to this program introduced a quarterly release model with support available, renamed to 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.[46] The first release of this distribution was OpenSolaris 2008.05.

The Solaris Express Community Edition (SXCE) is intended specifically for OpenSolaris developers.[47] It is updated every two weeks. 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.
