Problem

Der Neustart von AEM dauert lange. Die Thread-Sicherungskopien, die das Programm während des Neustarts anfertigt, zeigen die folgenden Threads an, die den Start von AEM verzögern:

Umgebung

AEM 6.2

Ursache

In der Warteschlange standen sehr viele Sling-Aufträge (Replikation, Workflow etc.) aus, als AEM beendet wurde. Beim Neustart von AEM werden die Aufträge erneut ihren Warteschlangen zugewiesen. Dieser Vorgang kann sehr lange dauern, wenn in der Warteschlange Tausende Aufträge vorhanden sind.

I. Löschen Sie überschüssige Sling-Aufträge

Nachdem AEM gestartet wurde, versuchen Sie, die Replikations-Warteschlangen zu entfernen und die Workflows zu bereinigen. Vergewissern Sie sich, dass während dieser Zeit möglichst wenige Anwender das System aktiv verwenden, da dieser Vorgang das System verlangsamen würde.

Überprüfen Sie die Replikations-Warteschlangen

Besuchen Sie http://aem-host:port/etc/replication/agent.author.html
Navigieren Sie zu einem beliebigen Agenten mit vielen ausstehenden Elementen.
Löschen Sie die Warteschlange, wenn sie nicht abgearbeitet wird

Überprüfen Sie die Workflow-Instanzen:

Besuchen Sie http://aem-host:port/workflow UI
Überprüfen Sie die Instanzen-Registerkarte, um festzustellen, ob sich dort viele laufende Workflows anhäufen
Besuchen Sie http://aem-host:port/system/console/jmx/com.adobe.granite.workflow%3Atype%3DMaintenance
Verwenden Sie die purgeActive-JMX-Methode, um die aktiven Workflows zu löschen (wenn dies sicher ist)

Bereinigen Sie Auftragsknoten:

Wenn keine der obigen Optionen die Dauer des Hoch- und Herunterfahrens reduziert, dann löschen Sie die Sling-Aufträge manuell:

Klicken Sie auf http://aem-host:port/crx/explorer/index.jsp und melden Sie sich dort als Admin an.
Öffnen Sie den Content Explorer
Navigieren Sie zu /var/eventing/jobs
Erfahren Sie, welche Aufträge unter /var/eventing/jobs/assigned/{sling id} angereiht werden
Klicken Sie dort mit der rechten Maustaste auf einen Unterordner, den Sie nicht beibehalten müssen, und wählen Sie Rekursiv löschen
Aktivieren Sie die Option Vorläufigen Scan deaktivieren
Klicken Sie Löschen

WARNUNG: Während des Löschens kann AEM sehr langsam sein, es wird empfohlen, dass Sie ein Ausfallfenster von einigen Stunden einplanen, um diese Löschung durchzuführen.

II. Neuestes AEM Cumulative Fix Pack installieren

Um die Auswirkungen des Ladens von Sling-Aufträgen beim Start zu verringern, ist in AEM6.2 CFP1 ein Fix enthalten, der diese Aufträge in einem Hintergrund-Thread lädt. Siehe 6.2 Hotfix-Seite, um diesen Fix zu erhalten.
