ActiveMQ 서비스를 위해 HA를 구현하는 데 약간의 어려움에 직면 해 있습니다. 지금, 나는 활성 MQ의 마스터 / 슬레이브 브로커를 올바르게 구현 했으므로 마스터가 죽으면 슬레이브는 메시지 전달을 투명하게 인수합니다. 둘 다 메시지를 저장하기 위해 Microsoft SQL 데이터베이스를 공유합니다.
다른 수준의 고 가용성을 추가하여 데이터베이스 미러링을 보장하고 싶었습니다. 이와 마찬가지로, 주요 DB 서버가 사망하면 중개인이 거울로 전환합니다. 미러링을 올바르게 설정했습니다. (데이터는 보조 DB 서버에 올바르게 반영됩니다).
문제는 DB 장애 조치가 모든 것을 엉망으로 만든다는 것입니다.
아시다시피, ActiveMQ 브로커의 마스터 / 슬레이브 ha는 다음과 같이 작동합니다. 마스터는 DB를 잠그고 슬레이브가 가져 가려고합니다. 마스터가 사망하자마자 자물쇠를 해방시키고 슬레이브가 인계되고 클라이언트가 새로운 것을 전환합니다. 문제는 DB 미러링과 함께 제공됩니다. Principal DB 서버를 종료하면 마스터가 데이터베이스 잠금을 업데이트하지 못합니다. 반면에, 노예는 그가 주요 DB 서버에서 잠금을 취할 수 없을 때, 2 차를 시도하고 물론 거울 상태에있는 것처럼 할 수는 없습니다.
ActiveMQ에 마스터 / 슬레이브 ha를 사용하지 않으면 DB 미러링이 작동합니다.
마스터의 구성 파일과 로그는 다음과 같습니다.

해결책
나는 당신이 새로운 마스터/슬레이브의 풍미가 필요하다고 생각합니다 - 추가 된 개선 - https://issues.apache.org/activemq/browse/amq-2387
다른 팁
NetworkConnector에 사용자 이름과 비밀번호를 추가하십시오. 기본값은 다음과 같습니다.
username = "system"password = "manager", 브로커는 올바른 권한없이 메시지와 큐를 전달하지 않습니다.
