Frage

Ich bin vor ein bisschen schwer HA für meine ActiveMQ Service zu implementieren. Im Moment habe ich korrekt umgesetzt, die Master / Slave-Broker von Active MQ, so dass, wenn der Meister stirbt, nimmt der Slave über die Nachrichtenübermittlung transparent. Beide teilen sich eine Microsoft SQL-Datenbank, die Nachrichten zu speichern.

Ich wollte eine andere Ebene der Hochverfügbarkeit hinzufügen möchten, eine Datenbankspiegelung zu gewährleisten. Wie diese, wenn der Auftraggeber DB-Server stirbt, wird der Makler auf den gespiegelten umschalten. Ich habe richtig die Spiegelung einrichten. (Die Daten werden an den sekundären Server DB korrekt gespiegelt).

Das Problem ist, dass die DB-Failover alles vermasseln.

Wie Sie wissen, arbeitet der Master / Slave-HA der ActiveMQ-Broker wie folgt: Der Master nimmt das Schloss in der DB und der Slave versucht, es zu nehmen. Sobald der Meister stirbt, befreit sie das Schloss und der Slave übernimmt und die Clients wechselt in den neuen. Problem kommt mit der DB-Spiegelung. wenn ich Abschaltung des Haupt DB-Server, schlägt der Master die Datenbanksperren zu aktualisieren. Auf der anderen Seite, den Sklaven, wenn er nicht in der Lage die Sperre in dem Haupt DB-Server zu übernehmen, die sekundäre versucht, und natürlich kann er nicht, wie es in dem gespiegelten Zustand.

Wenn ich nicht die Master / Slave-HA für activeMQ verwenden (nur ein Broker dann) der DB-Spiegelung funktioniert.

Hier sind die Konfigurationsdatei und Protokoll des Masters:

War es hilfreich?

Lösung

Ich glaube, Sie benötigen einen neuen Geschmack von Master / Slave - eine Verbesserung hinzugefügt - siehe https://issues.apache.org/activemq/browse/AMQ-2387

Andere Tipps

Bitte versuchen Sie Benutzername und Passwort an den networkConnector hinzufügen. Dies ist standardmäßig:

username = „System“ password = „Manager“, Makler nicht nur Weiterleiten von Nachrichten und Warteschlangen ohne die richtigen Rechte.
