 Damit Änderungen der Plugins wirksam werden, muss der SCM-Manager-Server neu gestartet werden. Das kann nach jeder einzelnen Aktion erfolgen. Es ist aber auch möglich viele unterschiedliche Aktionen wie Installieren, Aktualisieren und Löschen in eine Warteschlange einzureihen und alle Aktionen mit einem einzigen Neustart auszuführen. Wird eine Aktion (Installieren, Deinstallieren, Aktualisieren) für ein Plugin ausgewählt, erscheinen die Schaltflächen „Änderungen ausführen“ und „Änderungen abbrechen“. Über „Änderungen ausführen“ öffnet sich ein Pop-Up Fenster, in dem die aktuelle Warteschlange (alle ausgeführten Aktionen ohne Neustart) angezeigt werden. Der Anwender hat nun die Möglichkeit zu entscheiden, ob die Änderungen durch einen Neustart ausgeführt werden sollen. Falls Aktionen, die sich bereits in der Warteschlange befinden nicht mehr erwünscht sind, kann die gesamte Warteschlange über den Button „Änderungen abbrechen“ verworfen werden.

 Der SCM-Manager kann ein Plugin-Center anbinden, um schnell und bequem Plugins verwalten zu können. Um ein anderes SCM-Plugin-Center als das vorkonfigurierte zu verwenden, reicht es aus diese URL zu ändern. Läuft der SCM-Manager im Cloudogu EcoSystem, kann die Plugin-Center URL über einen Eintrag im etcd gesetzt werden.
-Wenn das vorkonfigurierte Plugin-Center verwendet wird, kann der SCM-Manager mit der cloudogu platform verbunden werden. 
-
-Nach der initialen Einrichtung sind folgende Werte standardgemäß hinterlegt:
-```markdown
-Plugin Center URL: https://plugin-center-api.scm-manager.org/api/v1/plugins/{version}?os={os}&arch={arch}&jre={jre}
-Plugin Center Authentication URL: https://plugin-center-api.scm-manager.org/api/v1/auth/oidc

-![Einstellungen, Plugin-Center nicht mit der cloudogu platform verbunden](assets/administration-settings-not-connected.png)

 In order for changes to plugins to become effective, the SCM-Manager server needs to be restarted. That can be done after every single action. It is also possible to queue several actions like the installation of a new plugin, updates or the deletion of a plugin and to perform all actions with one restart. If an action (installation, uninstallation, update) for a plugin was performed, the buttons "Execute changes" and "Abort changes"  appear. If you choose to execute  the changes, a popup window that shows the current queue (all actions without a restart) appears. Now the user can decide whether to execute the changes by restarting the server. If there are actions in the queue that are no longer desired, the queue can be emptied with the abort changes button.
