Solaris is a Unix operating system originally developed by Sun Microsystems. It superseded their earlier SunOS in 1993. In 2010, after the Sun acquisition by Oracle, it was renamed Oracle Solaris.
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: Berkeley Software Distribution, UNIX 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. The justification for this new overbrand was that it encompassed not only SunOS, but also the Open Windows graphical user interface and Open Network Computing (ONC) functionality.Although SunOS 4.1.x micro releases were retroactively named Solaris 1 by Sun, the Solaris name is used almost exclusively to refer only to the releases based on SVR4-derived SunOS 5.0 and later.
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.A port of Solaris to the Intel Itanium architecture was announced in 1997 but never brought to market.On November 28, 2007, IBM, Sun, and Sine Nomine Associates demonstrated a preview of Open Solaris 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.
