我在爲我的ActiveMQ服務實現HA時遇到了一些困難。 現在，我已經正確實現了Active MQ的主/從代理，所以如果主服務器死了，從服務器會透明地接管消息傳遞。他們都共享一個Microsoft SQL數據庫來存儲消息。ActiveMQ服務故障轉移和數據庫故障轉移
我想添加另一級別的高可用性，確保數據庫鏡像。像這樣，如果主體DB服務器死亡，代理將切換到鏡像服務器。 我已經正確設置了鏡像。 （數據正確鏡像到輔助數據庫服務器）。
問題是數據庫故障轉移會混淆一切。
如您所知，ActiveMq代理的主/從HA的工作方式如下：主服務器獲取數據庫中的鎖，並且從服務器嘗試使用它。一旦主人死亡，它就釋放鎖，從屬者接管並且客戶端切換到新的。 數據庫鏡像存在問題。當我關閉主體數據庫服務器時，主機無法更新數據庫鎖定。 另一方面，從服務器無法取得主DB服務器的鎖時嘗試次服務器，當然他不能，因爲它處於鏡像狀態。
如果我不使用masterMQ的主/從HA（只有一個代理，那麼）數據庫鏡像的作品。

其實這也是一個非常有用的信息和平。與這個acticeMQ配置無關，但它解決了我的代理配置中的一個問題。非常感謝你 ：） – srodriguez 2009-09-28 03:10:49
