| 81 | Die Lernplattform ist eine web-basierte Anwendung und hauptsächlich in Java geschrieben. Folgende Standardanwendungen werden unterstützt: | ||
| 82 | |||
| 83 | * Web-Server: Apache | ||
| 84 | * Applikations-Server: Tomcat | ||
| 85 | * Verwaltung von Daten: PostgreSQL, XML | ||
| 86 | |||
| 87 | Zur Nutzung dieser Lernplattform benötigen Sie eine Internetverbindung sowie einen Browser (Google Chrome, Mozilla Firefox, Internet Explorer, etc). | ||

| 117 | == Software == | ||
| 118 | |||
| 119 | Wir empfehlen Linux (64bit). | ||
| 120 | Folgende Distributionen werden aktuell für Produktivinstanzen verwendet: | ||
| 121 | |||
| 122 | * Scientific Linux | ||
| 123 | * Red Hat Enterprise Linux | ||
| 124 | * Ubuntu | ||
| 125 | * Open Suse | ||
| 126 | * SUSE Linux Enterprise Server. | ||
| 127 | |||
| 128 | Andere Distributionen sind möglich. | ||
| 129 | |||
| 130 | === Softwarekomponenten === | ||
| 131 | |||
| 132 | * Webserver: Apache Webserver + mod_ssl (mod_jk oder proxy_ajp) | ||
| 133 | * Datenbankserver: Postgresql | ||
| 134 | * Applicationserver: Java 17, Apache Tomcat 9 | ||
| 135 | |||
| 136 | === Verteilung === | ||
| 137 | |||
| 138 | * bis 300 gleichzeitige Nutzer : alle Komponenten auf einen Server | ||
| 139 | * bis 500 gleichzeitige Nutzer: Trennung zwischen Datenbankserver und Applicationserver | ||
| 140 | * bis 800 gleichzeitige Nutzer: Trennung zwischen Datenbankserver, Applicationserver und Webserver | ||
| 141 | * bis 1200 gleichzeitige Nutzer: mehrere OPAL-Nodes auf dem Applicationserver | ||
| 142 | * ab ca. 1500 gleichzeitige Nutzer: mehrere Applicationserver | ||
