'''Oracle Solaris''' is a [[proprietary software|proprietary]] [[Unix]] [[operating system]] offered by [[Oracle Corporation|Oracle]] for [[SPARC]] and [[x86-64]] based [[workstation]]s and [[server (computing)|servers]]. Originally developed by [[Sun Microsystems]] as Solaris, it superseded the company's earlier [[SunOS]] in 1993 and became known for its [[scalability]], especially on SPARC systems, and for originating many innovative features such as [[DTrace]], [[ZFS]] and Time Slider.<ref>{{cite news |author=Michael Totty |date=September 11, 2006 |title=Innovation Awards: The Winners Are... |url=http://online.wsj.com/public/article/SB115755300770755096-Puh3Kr2L9dGEhvkWyO94UivIRwA_20070910.html |access-date=July 5, 2008 |work=[[Wall Street Journal]] |quote=The DTrace trouble-shooting software from Sun was chosen as the Gold winner in The Wall Street Journal's 2006 Technology Innovation Awards contest |archive-date=July 5, 2008 |archive-url=https://web.archive.org/web/20080705214128/http://online.wsj.com/public/article/SB115755300770755096-Puh3Kr2L9dGEhvkWyO94UivIRwA_20070910.html |url-status=bot: unknown }}</ref><ref>{{cite web |date=January 2008 |title=2008 Technology of the Year Awards: Storage – Best File System |url=http://www.infoworld.com/slideshow/2008/01/150-2008_technology-2.html |url-status=dead |archive-url=https://web.archive.org/web/20080703030515/http://www.infoworld.com/slideshow/2008/01/150-2008_technology-2.html |archive-date=July 3, 2008 |access-date=July 5, 2008 |work=[[InfoWorld]]}}</ref> After the [[Acquisition of Sun Microsystems by Oracle Corporation|Sun acquisition by Oracle]] in 2010, it was renamed Oracle Solaris.<ref>{{cite web
