Pergunta

Eu estou enfrentando um pouco de dificuldades de execução da HA para o meu serviço ActiveMQ. Agora, eu tenho implementado corretamente o Master / Slave corretores do Active MQ, por isso, se as matrizes mestre, o escravo assume a entrega de mensagens de forma transparente. Ambos compartilham um banco de dados Microsoft SQL para armazenar as mensagens.

Eu queria adicionar outro nível de alta disponibilidade, garantindo um espelhamento de banco de dados. Assim, se as matrizes de servidor de DB principais, os corretores irá mudar para o espelhado. Eu configurar corretamente o espelhamento. (Os dados são corretamente espelhado para o servidor DB secundário).

O problema é que as messes DB failover tudo.

Como você sabe, o mestre / escravo HA das obras corretores activemq da seguinte forma: o mestre toma o bloqueio no banco de dados e as tentativas de escravos para levá-lo. Assim que as matrizes mestre, ele libera o bloqueio e o escravo assume e os clientes muda para o novo. Problema vem com o espelhamento DB. quando desligar o servidor principal DB i, o mestre não consegue atualizar os bloqueios de banco de dados. Por outro lado, o escravo, quando ele é incapaz de tomar o bloqueio no servidor principal DB, tenta o secundário e, claro, ele não pode, como é no estado espelhado.

Se eu não usar o master / slave HA para activeMQ (apenas um corretor de então) o DB espelhamento obras.

Aqui estão os arquivos de configuração e log do mestre:

Solução

Eu acho que você precisa de um novo sabor de master / slave - acrescentou uma melhoria - veja https://issues.apache.org/activemq/browse/AMQ-2387

Outras dicas

Por favor, tente adicionar usuário e senha para o NETWORK. Padrão, isto é:

username = "sistema" password = "manager", corretores Não basta encaminhar mensagens e filas sem os direitos corretos.
