title="Besturingssysteem">besturingssysteem</a> dat computerbedrijf <a href="/wiki/Digital_Equipment_Corporation" title="Digital Equipment Corporation">Digital Equipment Corporation</a> ('DEC' of kortweg 'Digital') ontwikkelde voor zijn <a href="/wiki/VAX" title="VAX">VAX</a>-<a href="/wiki/Minicomputer" title="Minicomputer">minicomputerserie</a>. </p><p>In <a href="/wiki/1978" title="1978">1978</a> is het op de markt gekomen. VMS was het eerste besturingssysteem met virtueel geheugenbeheer. </p><p>Later ontwikkelde Digital de 64-bits <a href="/wiki/DEC_Alpha" title="DEC Alpha">Alpha-processor</a> en bracht ook een versie van VMS hiervoor uit. Sindsdien wordt VMS als OpenVMS op de markt gebracht en werden ook de versienummers gelijkgetrokken. Nog later werd ook een versie voor de <a href="/wiki/Intel" title="Intel">Intel</a>-<a href="/wiki/Itanium" title="Itanium">Itaniumprocessor</a> ontwikkeld. </p><p>Het staat bekend als bijzonder robuust en veelzijdig, is schaalbaar van desktop <a href="/wiki/Workstation" class="mw-redirect" title="Workstation">workstation</a> tot groot <a href="/wiki/Datacentrum" class="mw-redirect" title="Datacentrum">datacentrum</a> en is nog steeds in gebruik in de industrie en bij veel grote instellingen. </p><p>OpenVMS is beschikbaar voor de volgende hardwareplatforms: </p> <ol><li><a href="/wiki/VAX" title="VAX">VAX</a></li> <li><a href="/wiki/DEC_Alpha" title="DEC Alpha">Alpha</a></li> <li><a href="/wiki/IA-64" title="IA-64">IA-64</a></li> <li><a href="/wiki/X86-64" title="X86-64">x86-64</a></li></ol> <p>Het besturingssysteem OpenVMS wordt nu ontwikkeld door <a href="/wiki/Hewlett-Packard" title="Hewlett-Packard">Hewlett-Packard</a>. Vooral in de financiële sector wordt het nog veel gebruikt. Het wordt beschouwd als het meest veilige besturingssysteem, en heeft geavanceerde clustertechnologie. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Gebruikersinterface">Gebruikersinterface</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OpenVMS&veaction=edit&section=1" title="Bewerk dit kopje: Gebruikersinterface" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=OpenVMS&action=edit&section=1" title="De broncode bewerken van de sectie: Gebruikersinterface"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>De gebruikersinterface was oorspronkelijk een tekstterminalomgeving, waar DCL (Digital Command Language) op beschikbaar was. DCL-opdrachten hebben een <a href="/wiki/Syntaxis_(informatica)" title="Syntaxis (informatica)">syntaxis</a> die op normaal Engels lijkt en een bijzonder uitgebreide helpfunctie. Daarnaast zijn alle gangbare programmaconstructies beschikbaar (zoals 'if-then-else' en variabelen), zodat in DCL ook complete programma's geschreven kunnen worden. </p><p>Later zijn verschillende grafische gebruikersomgevingen geïntroduceerd, die vrijwel allemaal op <a href="/wiki/X_Window_System" title="X Window System">X Window</a> gebaseerd zijn. De laatste is <a href="/wiki/Common_Desktop_Environment" title="Common Desktop Environment">CDE</a> (<i>Common Desktop Environment</i>), die eenzelfde uiterlijk en bediening heeft op alle platformen die het ondersteunen. </p> <div class="mw-heading mw-heading2"><h2 id="Techniek">Techniek</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OpenVMS&veaction=edit&section=2" title="Bewerk dit kopje: Techniek" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=OpenVMS&action=edit&section=2" title="De broncode bewerken van de sectie: Techniek"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Een van de redenen voor de grote robuustheid is de manier waarop het geheugen beheerd wordt. De <a href="/wiki/Hardware" title="Hardware">hardware</a> van de VAX en latere processors staat toe het geheugen in verschillende <i>modi</i> te benaderen. Deze modi (USER, EXECUTIVE, SUPERVISORY en SYSTEM) bepalen de rechten die het besturingssysteem en de <a href="/wiki/Applicatie" title="Applicatie">applicaties</a> op bepaalde systeembronnen hebben. Omdat applicatieprogramma's standaard in de minst krachtige modus (USER) werken en omdat wisselen van modus door de hardware bepaald wordt, is misbruik door zogenaamde <a href="/wiki/Bufferoverloop" title="Bufferoverloop">bufferoverloop</a> geheel onmogelijk. Programma's die zich misdragen worden afgebroken met de melding 'access violation'. </p> <div class="mw-heading mw-heading2"><h2 id="Beschikbaarheid">Beschikbaarheid</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OpenVMS&veaction=edit&section=3" title="Bewerk dit kopje: Beschikbaarheid" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=OpenVMS&action=edit&section=3" title="De broncode bewerken van de sectie: Beschikbaarheid"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Het is mogelijk met VMS <a href="/wiki/Computercluster" title="Computercluster">clusters</a> te bouwen die een uiterst hoge beschikbaarheid hebben. Een extreem voorbeeld is het cluster van de regiopolitie Amsterdam-Amstelland dat op 13 april 2007 een uptime van tien jaar had. Gedurende die tien jaar is alle hardware vervangen en is de helft van het cluster verhuisd naar een andere locatie 7 km verderop zonder dat het cluster down en/of applicaties down zijn gegaan. Hiermee is dit cluster dus een multi-site cluster. Mede ook in deze tien jaar is alle data van DAS-schijven naar SAN-schijven verhuisd zonder dat hiervoor applicaties down zijn gegaan. Ook de <a href="/wiki/Software" title="Software">software</a> is volledig anders dan waarmee begonnen is. Sommige applicaties worden online geüpgraded waardoor deze voor de gebruikers niet gestopt hoeven te worden. Ook VMS zelf is van 6.2 geüpgraded naar inmiddels 7.3-2 met de laatste patches. Ook hiervoor ging het VMS-cluster niet down. Sommige applicaties worden per maand geüpgraded. Het systeem is dusdanig ingericht dat er meerdere versies van dezelfde applicatie gelijktijdig operationeel kunnen zijn (en soms ook daadwerkelijk zijn). </p> <div class="mw-heading mw-heading2"><h2 id="Trivia">Trivia</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OpenVMS&veaction=edit&section=4" title="Bewerk dit kopje: Trivia" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=OpenVMS&action=edit&section=4" title="De broncode bewerken van de sectie: Trivia"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>Op de <a href="/wiki/Hacker" title="Hacker">hacker</a>-conferentie <a href="/wiki/DEF_CON" title="DEF CON">DEF CON</a> werd VMS tot 'onhackbaar' uitgeroepen.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup></li> <li>Een aantal ex-ontwikkelaars van VMS heeft aan de wieg gestaan van <a href="/wiki/Windows_NT" title="Windows NT">Windows NT</a>, de afkorting WNT staat ook net één letter verder in het alfabet dan VMS (naar analogie van <a href="/wiki/IBM" title="IBM">IBM</a> - <a href="/wiki/HAL_9000" title="HAL 9000">HAL</a>).</li></ul> <div class="mw-heading mw-heading2"><h2 id="Externe_links">Externe links</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=OpenVMS&veaction=edit&section=5" title="Bewerk dit kopje: Externe links" class="mw-editsection-visualeditor"><span>bewerken</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=OpenVMS&action=edit&section=5" title="De broncode bewerken van de sectie: Externe links"><span>brontekst bewerken</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r67679320"><span class="taalaanduiding" title="Taal: Engels">(<span>en</span>) </span><a rel="nofollow" class="external text" href="https://www.vmssoftware.com">VMS Software Inc.</a></li> <li><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r67679320"><span class="taalaanduiding" title="Taal: Engels">(<span>en</span>) </span><a rel="nofollow" class="external text" href="https://web.archive.org/web/20150321120722/http://www.openvms.org/">Onofficiële OpenVMS website</a></li> <li><link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r67679320"><span class="taalaanduiding" title="Taal: Engels">(<span>en</span>) </span><a href="https://en.wikipedia.org/wiki/DIGITAL_Command_Language" class="extiw" title="en:DIGITAL Command Language">DCL</a> op de <a href="/wiki/Engelstalige_Wikipedia" title="Engelstalige Wikipedia">Engelstalige Wikipedia</a>.</li></ul> <div class="toccolours appendix" role="presentation" style="font-size:90%;
