Server error logs

 Es gibt einige Fehler in der Systemkonfiguration.

    AppAPI-Bereitstellungs-Daemon
    Der Standard-Deploy-Daemon von AppAPI ist nicht eingerichtet. Bitte in den Einstellungen einen Standard-Deploy-Daemon registrieren, um externe Apps (Ex-Apps) zu installieren.

Fehler im Protokoll
24 Fehler in den Protokollen seit 27. November 2025, 19:26:37
MIME-Type-Migrationen verfügbar
Eine oder mehrere MIME-Type-Migrationen sind verfügbar. Gelegentlich werden neue MIME-Typen hinzugefügt, um bestimmte Dateitypen besser handhaben zu können. Die Migration der MIME-Typen dauert bei größeren Instanzen lange, daher erfolgt sie bei Upgrades nicht automatisch. Verwende den Befehl `occ maintenance:repair --include-expensive`, um die Migrationen durchzuführen.
In der Datenbank fehlen Indizes
Einige fehlende optionale Indizes wurden erkannt. Gelegentlich werden neue Indizes hinzugefügt (von Nextcloud oder installierten Anwendungen), um die Datenbankleistung zu verbessern. Das Hinzufügen von Indizes kann manchmal eine Weile dauern und die Leistung vorübergehend beeinträchtigen, daher wird dies bei Upgrades nicht automatisch durchgeführt. Sobald die Indizes hinzugefügt wurden, sollten Abfragen an diese Tabellen schneller sein. Bitte den Befehl `occ db:add-missing-indices` verwenden, um sie hinzuzufügen. Fehlende Indizes: "properties_name_path_user" in Tabelle "properties", "systag_objecttype" in Tabelle "systemtag_object_mapping", "unique_category_per_user" in Tabelle "vcategory", "calobjects_by_uid_index" in Tabelle "calendarobjects", "cards_prop_abid_name_value" in Tabelle "cards_properties"

    PHP OPcache
    Das PHP OPcache-Modul ist nicht ordnungsgemäß konfiguriert. Der "OPcache interned strings"-Puffer ist fast voll. Um sicherzustellen, dass sich wiederholende Strings effektiv zwischengespeichert werden können, wird empfohlen, "opcache.interned_strings_buffer" mit einem Wert größer als "8" in der PHP-Konfiguration zu setzen..

Transaktionale Dateisperre
Die Datenbank wird für transaktionale Dateisperren verwendet. Um die Leistung zu verbessern, konfiguriere bitte Memcache, falls verfügbar.
Memcache
Es wurde kein Speichercache konfiguriert. Um die Leistung zu verbessern, sofern verfügbar, bitte Memcache konfigurieren.
Datenbankversion
MariaDB Version 10.3 erkannt, diese Version hat das Ende ihres Lebenszyklus erreicht und wird nur noch als Teil von Ubuntu 20.04 unterstützt. Für optimale Leistung, Stabilität und Funktionalität mit dieser Version von Nextcloud wird MariaDB >= 10.6 und 11.8 <= empfohlen.
