我在为ActiveMQ服务实现HA方面遇到了一些困难。 现在，我已经正确实现了Active MQ的Master / Slave代理，所以如果master死了，slave会透明地接管消息传递。它们共享一个Microsoft SQL数据库来存储消息。
我想添加另一个级别的高可用性，确保数据库镜像。像这样，如果主DB服务器死了，代理将切换到镜像服务器。 我已经正确设置了镜像。 （数据正确镜像到辅助DB服务器）。
问题是数据库故障转移会弄乱一切。
如您所知，ActiveMq代理的主/从HA的工作原理如下：主服务器获取数据库中的锁，而从服务器尝试接受它。一旦主设备死机，它就会释放锁定，从设备接管并且客户端切换到新设备。 DB镜像出现问题。当我关闭主数据库服务器时，主服务器无法更新数据库锁。 另一方面，当奴隶无法在主DB服务器中取锁时，会尝试辅助，当然他不能，因为它处于镜像状态。
如果我不使用主/从HA用于activeMQ（那时只有一个代理），则DB镜像可以正常工作。
以下是主服务器的配置文件和日志：

我认为你需要一种新的主/从风格 - 增加了改进 - 见https://issues.apache.org/activemq/browse/AMQ-2387
答案 1 :(得分：0)
请尝试将userName和密码添加到networkConnector。默认，这是：
userName =“system”password =“manager”，经纪人不只是在没有正确权利的情况下转发邮件和队列。
