Umgebung

AEM 6.2 / Oak 1.4.0-1.4.9

Ursache

Der bekannte Fehler OAK-5005 ist für dieses Problem verantwortlich.

Lösung

  1. Um die fehlenden Blobs wiederherzustellen, folgen Sie den Schritten, um fehlende Datenspeicherdateien wiederherzustellen.

  2. Laden Sie dieselben fehlenden Blobs mit dem „aws s3 cp“-Befehlszeilenwerkzeug auf S3 hoch.

  3. Installieren Sie den neuesten AEM 6.2 Oak-Hotfix.
