Bitte helfen Sie mir, dieses Problem zu lösen.

Answer 1

Der Fehler zeigt an, dass der Vora Katalog ist entweder nicht installiert oder nicht korrekt ausgeführt wird.

Da der Vora Katalog beruht auf der Vora DLoG, die DLoG muss auch installiert und ausgeführt werden. Anweisungen zur Installation finden Sie unter Vora Installation and Administration Guide. Sie können die Benutzeroberfläche des Vora Discovery Servers (: 8500/ui) auf einen 'grünen' Eintrag für 'vora-catalog' und 'dlog' überprüfen. Bei Problemen können Sie die Protokolldateien/var/log/vora-catalog und/var/log/vora-dlog überprüfen.
