112-643: A Terminate-and-stay-resident (TSR) program to the DOS kernel. Once loaded as a TSR, iRMX takes over the CPU, changing to protected mode and running DOS in a virtual machine within an RMX task. This combination provides RMX real-time functionality as well as full DOS services. Like DOS-RMX, this system provides a hybrid mixture of services and capabilities defined by DOS, Windows, and iRMX. Inter-application communication via an enhanced Windows DDE capability allows RMX tasks to communicate with Windows processes. iRMX for Windows
168-520: A stand-alone node of the INtime RTOS. Unlike Windows, INtime can run on an Intel 80386 or equivalent processor. Current versions of the Windows operating system generally require at least a Pentium level processor in order to boot and execute. The introduction of INtime 3.0 included several important enhancements. Among them, support for multi-core processors and the ability to debug real-time processes on
224-594: 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
280-477: A general-purpose operating system on a single hardware platform. INtime 1.0 was originally introduced in 1997 in conjunction with the Windows NT operating system. Since then it has been upgraded to include support for all subsequent protected-mode Microsoft Windows platforms, including Windows Vista and Windows 7. INtime can also be used as a stand-alone RTOS. INtime binaries are able to run unchanged when running on
336-490: A large layoff of Solaris development engineering staff, development continued and Solaris 11.4 was released in 2018. Solaris uses a common code base for the platforms it supports: 64-bit SPARC and x86-64 . Solaris has a reputation for being well-suited to symmetric multiprocessing , supporting a large number of CPUs . It has historically been tightly integrated with Sun's SPARC hardware (including support for 64-bit SPARC applications since Solaris 7), with which it

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
504-545: A similar, although less complex, Westinghouse-supplied iRMX control system through the central Common Tunnel tracks. This was expected to be decommissioned in 2011. Several variations of iRMX have been developed since its original introduction on the Intel 8080: iRMX I, II and III, iRMX-86, iRMX-286, DOS-RMX, iRMX for Windows, and, most recently, INtime. While many of the original variants of iRMX are still in use, only iRMX III, iRMX for Windows, and INtime are currently supported for
560-408: A single IBM PC compatible computer, where iRMX tasks (processes) have scheduling priority over the DOS kernel, interrupts, and applications. iRMX events (e.g., hardware interrupts) pre-empt the DOS kernel to ensure that tasks can respond to real-time events in a time-deterministic manner. In a functional sense, DOS-RMX is the predecessor to iRMX for Windows and INtime. In practice, DOS-RMX appears as

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 ,

#1732883586639672-466: A unified source code base. In 2011, the Solaris 11 kernel source code leaked . On September 2, 2017, Simon Phipps , a former Sun Microsystems employee not hired by Oracle in the acquisition, reported on Twitter that Oracle had laid off the Solaris core development staff, which many interpreted as sign that Oracle no longer intended to support future development of the platform. While Oracle did have

An installation need include only the components required: intertask synchronization, communication subsystems, a filesystem, extended memory management, command shell, etc. The native filesystem is specific to iRMX, but has many similarities to the original Unix (V6) filesystem, such as 14 character path name components, file nodes, sector lists, application readable directories, etc. iRMX supports multiple processes (known as jobs in RMX parlance) and multiple threads are supported within each process (task). In addition, interrupt handlers and threads exist to run in response to hardware interrupts. Thus, iRMX
896-545: Is an automatic train operation line. Automatic train protection is by trackside and train borne equipment that does not use iRMX. It is the automatic train supervision elements that use a mix of iRMX on Multibus, and Solaris on SPARC computers. 16 iRMX local site computers are distributed along the Central line together with 6 central iRMX computers at the control centre. All 22 iRMX computers are dual redundant. As of 2011 iRMX CLSCS continues in full operation. Oslo Metro uses
952-557: 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. The Java Desktop System is not included in Solaris 11 which instead ships with a stock version of GNOME. Likewise, CDE applications are no longer included in Solaris 11, but many libraries remain for binary backwards compatibility. The open source desktop environments KDE and Xfce , along with numerous other window managers , also compile and run on recent versions of Solaris. Sun
1008-462: Is called Solaris Containers for Linux Applications (SCLA), based on the branded zones functionality introduced in Solaris 10 8/07. 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. The DVD ISO image can be used to load Solaris, running in-memory, rather than initiating

However, it has supported x86 systems since Solaris 2.1 and 64-bit x86 applications since Solaris 10, allowing Sun to capitalize on the availability of commodity 64-bit CPUs based on the x86-64 architecture. Sun heavily marketed Solaris for use with both its own x86-64-based Sun Java Workstation and
1176-862: Is possible to port and run some older iRMX applications that use segmented addressing to the INtime kernel. When Intel introduced the Intel 80386 processor, in addition to expanding the iRMX RTOS to support 32-bit registers, iRMX III also included support for the four distinct protection rings (named rings 0 through 3) which describe the protected-mode mechanism of the Intel 32-bit architecture. In practice very few systems have ever used more than rings 0 and 3 to implement protection schemes. The I, II, III, -286 and -86 variants are intended as standalone real-time operating systems. A number of development utilities and applications were made for iRMX, such as compilers ( PL/M , Fortran , C ), an editor (Aedit), process and data acquisition applications and so on. Cross compilers hosted on

#17328835866391232-618: Is simple. But some cases may require quite a bit of fine-tuning. I think that Sun has put some really nice touches on Solaris 10 that make it a better operating system for both administrators and users. The security enhancements are a long time coming, but are worth the wait. Is Solaris 10 perfect, in a word no it is not. But for most uses, including a desktop OS I think Solaris 10 is a huge improvement over previous releases. We've had fun with Solaris 10. It's got virtues that we definitely admire. What it needs to compete with Linux will be easier to bring about than what it's already got. It could become

Be that as it may, since the Solaris 10 download is free, it behooves any IT manager to load it on an extra server and at least give it a try. Solaris 10 provides a flexible background for securely dividing system resources, providing performance guarantees and tracking usage for these containers. Creating basic containers and populating them with user applications and resources

For releases based on SunOS 5, the SunOS minor version is included in the Solaris release number. For example, Solaris 2.4 incorporates SunOS 5.4. After Solaris 2.6, the 2. was dropped from the release name, so Solaris 7 incorporates SunOS 5.7, and the latest release SunOS 5.11 forms the core of Solaris 11.4. Although SunSoft stated in its initial Solaris 2 press release their intent to eventually support both SPARC and x86 systems,

Updates to that project are built and delivered several times
1960-423: The Solaris teams. 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
2016-419: The compilers developed for iRMX include features to exploit the segmented addressing features of the original x86 architecture . The INtime variant of iRMX does not include explicit support for segmentation, opting instead to support only the simpler and more common 32-bit flat addressing scheme. Despite the fact that native processes written for INtime can only operate using unsegmented flat-mode addressing, it
2072-547: 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. A later change to this program introduced a quarterly release model with support available, renamed Solaris Express Developer Edition (SXDE). In 2007, Sun announced Project Indiana with several goals, including providing an open source binary distribution of

A significant architectural difference between the INtime RTOS and all other iRMX variants is the support for address segments (see x86 memory segmentation ). The original 8086 family of processors relied heavily on segment registers to overcome limitations associated with addressing large amounts of memory via 16-bit registers. The iRMX operating system and

An x86 version of Solaris 2.1 was released in June 1993, about 6 months after the SPARC version, as a desktop and uniprocessor workgroup server operating system. It included the Wabi emulator to support Windows applications. At the time, Sun also offered the Interactive Unix system that it had acquired from Interactive Systems Corporation . In 1994, Sun released Solaris 2.4, supporting both SPARC and x86 systems from
