ActiveMQ サービスの HA を実装するのに少し問題があります。現在、Active MQ のマスター/スレーブ ブローカーを正しく実装しているため、マスターが停止すると、スレーブが透過的にメッセージ配信を引き継ぎます。どちらも Microsoft SQL データベースを共有してメッセージを保存します。
データベースのミラーリングを確実にするために、別のレベルの高可用性を追加したいと考えていました。このように、プリンシパル DB サーバーが停止すると、ブローカーはミラー化されたサーバーに切り替わります。ミラーリングを正しくセットアップしました。(データはセカンダリ DB サーバーに正しくミラーリングされます)。
問題は、DB フェイルオーバーがすべてを台無しにすることです。
ご存じのとおり、ActiveMq ブローカーのマスター/スレーブ HA は次のように機能します。マスターは DB のロックを取得し、スレーブはそれを取得しようとします。マスターが停止するとすぐにロックが解放され、スレーブが引き継ぎ、クライアントは新しいマスターに切り替わります。DB ミラーリングに問題があります。プリンシパル DB サーバーをシャットダウンすると、マスターはデータベース ロックの更新に失敗します。一方、スレーブは、プリンシパル DB サーバーでロックを取得できない場合、セカンダリを試行しますが、ミラーリングされた状態であるため、もちろんできません。
ActiveMQ にマスター/スレーブ HA を使用しない場合 (その場合は 1 つのブローカーのみ)、DB ミラーリングは機能します。
マスターの構成ファイルとログは次のとおりです。
