题

我现在面临一个位执行HA我的ActiveMQ服务的困难。 现在，我已经正确地实施主动MQ的主/从经纪人，所以如果主人死了，从接管消息传送透明。他们都共享一个Microsoft SQL数据库来存储信息。

我想添加高可用性的另一个层面，确保了数据库镜像。与此类似，如果主数据库服务器死亡，经纪人将切换到镜像之一。 我已经设置了正确的镜像。 （数据被正确地反映到次级DB服务器）。

的问题是，所述故障转移DB弄乱一切。

大家知道，所述的ActiveMQ经纪人的主/从HA的工作原理如下：在主开出锁定在DB和从试图把它。只要主人死了，就释放锁，并从接管和客户端切换到新的一个。 问题自带的数据库镜像。当我关闭主DB服务器上，主未能更新数据库锁。 在另一方面，从属，当他无法采取锁定在主DB服务器，尝试二次当然他不能，因为它是在镜像状态。

如果我不使用主/从HA为ActiveMQ的（只有一个代理然后）的DB镜像作品。

有帮助吗？

解决方案

我想你需要主/从一种新口味 - 添加了改进 - 见 https://issues.apache.org/activemq/browse/AMQ-2387

其他提示

请尝试添加用户名和密码的networkConnector。默认情况下，这是：

的userName =“系统”密码=“经理”，经纪人不只是转发消息和队列没有正确的权利。
