Xsun is an X Window System (X11) display server implementation included with Solaris, developed by Sun Microsystems. It replaced the older Xnews server, which supported the display of not only X11 applications, but also NeWS and SunView programs. Xsun discontinued support for these legacy environments, and added support for Display PostScript.
Xsun was first released as part of Solaris 2.3 in November 1993. It was originally based on X11R5; the version included with Solaris 10 is based on X11R6.6.
Solaris 10 includes both Xsun and the X.Org Server, Xorg, the open-source software reference implementation of X, based on X11R7. The Xorg server was the most commonly used display server on x86 systems, while the Xsun server remained the most commonly used on SPARC systems; Xorg support for SPARC was only added in Solaris 10 8/07, and had very limited driver support. [1] The OpenSolaris project stated that the future direction of X support is the X.Org implementation. [2] Oracle Solaris 11, released in November, 2011, includes only the Xorg server (X.Org 1.10.3). [3]
In contrast to XFree86, Xsun implemented kernel-based mode setting for some graphics device drivers.
Sun Microsystems, Inc. was an American technology company that sold computers, computer components, software, and information technology services and created the Java programming language, the Solaris operating system, ZFS, the Network File System (NFS), and SPARC microprocessors. Sun contributed significantly to the evolution of several key computing technologies, among them Unix, RISC processors, thin client computing, and virtualized computing. Notable Sun acquisitions include Cray Business Systems Division, Storagetek, and Innotek GmbH, creators of VirtualBox. Sun was founded on February 24, 1982. At its height, the Sun headquarters were in Santa Clara, California, on the former west campus of the Agnews Developmental Center.
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris.
OpenStep is an object-oriented application programming interface (API) specification developed by NeXT. It provides a framework for building graphical user interfaces (GUIs) and developing software applications. OpenStep was designed to be platform-independent, allowing developers to write code that could run on multiple operating systems, including NeXTSTEP, Windows NT, and various Unix-based systems. It has influenced the development of other GUI frameworks, such as Cocoa for macOS, and GNUstep.
StarOffice is a discontinued proprietary office suite. Its source code continues today in derived open-source office suites Collabora Online and LibreOffice. StarOffice supported the OpenOffice.org XML file format, as well as the OpenDocument standard, and could generate PDF and Flash formats. It included templates, a macro recorder, and a software development kit (SDK).
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer.
X.Org Server is the free and open-source implementation of the X Window System (X11) display server stewarded by the X.Org Foundation.
Unix System V is one of the first commercial versions of the Unix operating system. It was originally developed by AT&T and first released in 1983. Four major versions of System V were released, numbered 1, 2, 3, and 4. System V Release 4 (SVR4) was commercially the most successful version, being the result of an effort, marketed as Unix System Unification, which solicited the collaboration of the major Unix vendors. It was the source of several common commercial Unix features. System V is sometimes abbreviated to SysV.
Xinerama is an extension to the X Window System that enables X applications and window managers to use two or more physical displays as one large virtual display.
Xgl is an obsolete display server implementation supporting the X Window System protocol designed to take advantage of modern graphics cards via their OpenGL drivers, layered on top of OpenGL. It supports hardware acceleration of all X, OpenGL and XVideo applications and graphical effects by a compositing window manager such as Compiz or Beryl. The project was started by David Reveman of Novell and first released on January 2, 2006. It was removed from the X.org server in favor of AIGLX on June 12, 2008.
OpenWindows is a discontinued desktop environment for Sun Microsystems workstations which combined a display server supporting the X Window System protocol, the XView and OLIT toolkits, the OPEN LOOK Window Manager (olwm), and the DeskSet productivity tools; earlier versions of OpenWindows also supported the NeWS protocol. It implements the OPEN LOOK GUI specification.
HotSpot, released as Java HotSpot Performance Engine, is a Java virtual machine for desktop and server computers, developed by Sun Microsystems which was purchased by and became a division of Oracle Corporation in 2010. Its features improved performance via methods such as just-in-time compilation and adaptive optimization. It is the de facto Java Virtual Machine, serving as the reference implementation of the Java programming language.
Sun Fire is a series of server computers introduced in 2001 by Sun Microsystems. The Sun Fire branding coincided with the introduction of the UltraSPARC III processor, superseding the UltraSPARC II-based Sun Enterprise series. In 2003, Sun broadened the Sun Fire brand, introducing Sun Fire servers using the Intel Xeon processor. In 2004, these early Intel Xeon models were superseded by models powered by AMD Opteron processors. Also in 2004, Sun introduced Sun Fire servers powered by the UltraSPARC IV dual-core processor. In 2007, Sun again introduced Intel Xeon Sun Fire servers, while continuing to offer the AMD Opteron versions as well.
In computer security, executable-space protection marks memory regions as non-executable, such that an attempt to execute machine code in these regions will cause an exception. It makes use of hardware features such as the NX bit, or in some cases software emulation of those features. However, technologies that emulate or supply an NX bit will usually impose a measurable overhead while using a hardware-supplied NX bit imposes no measurable overhead.
Solaris Containers is an implementation of operating system-level virtualization technology for x86 and SPARC systems, first released publicly in February 2004 in build 51 beta of Solaris 10, and subsequently in the first full release of Solaris 10, 2005. It is present in illumos distributions, such as OpenIndiana, SmartOS, Tribblix and OmniOS, and in the official Oracle Solaris 11 release.
Oracle Linux is a Linux distribution packaged and freely distributed by Oracle, available partially under the GNU General Public License since late 2006. It is compiled from Red Hat Enterprise Linux (RHEL) source code, replacing Red Hat branding with Oracle's. It is also used by Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata and others.
Xephyr is a display server software implementing the X11 display server protocol based on KDrive which targets a window on a host X Server as its framebuffer. It is written by Matthew Allum. Xephyr is an X-on-X implementation and runs on X.Org Server and can work with Glamor. Future versions could make use of libinput. Replacing Xephyr with the xf86-video-dummy and xf86-video-nested drivers in the normal X.Org server is being considered as part of X11R7.8.
Adaptive Internet Protocol (AIP) is a multi-channel protocol that allows an application running on any of multiple platforms to be displayed on any of a wide range of client systems. It supports rich remote display and input services with a number of display options to deliver the presentation of the remote applications onto the local display either as a standalone window, or within a contained remote environment delivered full-screen or in a standalone window. The protocol also supports audio, printing, and other device mapping services.
Sun xVM was a product line from Sun Microsystems that addressed virtualization technology on x86 platforms. One component was discontinued before the Oracle acquisition of Sun; the remaining two continue under Oracle branding.
Oracle VM Server for x86 is a server virtualization offering from Oracle Corporation. Oracle VM Server for x86 incorporates the free and open-source Xen hypervisor technology, supports Windows, Linux, and Solaris guests and includes an integrated Web based management console. Oracle VM Server for x86 features fully tested and certified Oracle Applications stack in an enterprise virtualization environment.
Illumos is a partly free and open-source Unix operating system. It is based on OpenSolaris, which was based on System V Release 4 (SVR4) and the Berkeley Software Distribution (BSD). Illumos comprises a kernel, device drivers, system libraries, and utility software for system administration. This core is now the base for many different open-sourced Illumos distributions, in a similar way in which the Linux kernel is used in different Linux distributions.
We've been working to migrate all of the existing libraries and clients to build from this source base as well for future Solaris releases, and have almost finished that now.
While Oracle Solaris 10 includes both the Xsun family of X servers, with Xsun as the default on SPARC platforms, and Xorg as the default on x86 platforms, Oracle Solaris 11 only supports the Xorg family of servers.
