Sun Solaris - Definition

The Solaris Operating Environment (OE) (Solaris) is a computer operating system, the proprietary Unix variant developed by Sun Microsystems (Solaris is slated to be released under an OSI certified Open-Source license with the release of Solaris 10 by the fifth week of 2005.)

Solaris 8 in the Common Desktop Environment (CDE)

Early versions, based on BSD UNIX, were called SunOS. The shift to a System V code base in SunOS 5 was marked by changing the name to Solaris 2. Earlier versions were retroactively named Solaris 1.x. After version 2.6, Sun dropped the "2." from the name; the most recent versions (as of early 2005) are Solaris 7, the 64-bit Solaris 8, Solaris 9 (released May 22, 2002), and Solaris 10 (released February 1, 2005).

The Solaris OE consists of the SunOS UNIX base operating system plus a graphical user environment. The first Solaris GUI was OpenWindows (http://docs.sun.com/app/docs/doc/806-2901). It was followed by CDE in Solaris 2.6. Sun's Java_Desktop_System, which is based on GNOME, is included with Solaris 10.

Solaris is primarily written to run on SPARC processors. There is also a version called Solaris x86 that runs on PCs. Solaris was also ported to the PowerPC architecture but the port was cancelled before being released as a product. Solaris 10 is available for x86-64 as well as SPARC and x86 architectures. Sun also plans to implement parts of Linux APIs in Solaris 10, allowing Solaris x86 to natively run Linux binaries.

Although based on a number of open standards, Solaris is proprietary rather than free software in terms of licensing. However, both binary and source versions have been downloadable without cost at various times. Sun recently confirmed (http://story.news.yahoo.com/news?tmpl=story&cid=562&e=7&u=/ap/sun_solaris10) their intention to make Solaris 10 free software under the OpenSolaris (http://blogs.sun.com/roller/page/jimgris/) project. Sun's Common Development and Distribution License, which was approved after review by Open Source Initiative, is a likely candidate to be the license for the free software version of Solaris.
