Chungnam National University Computer Science and Engineering Database System Laboratory JBoss Application ServerJBoss Enterprise SOA Platform, Portals State Replication 방법 Fine-Grained State Replication TreeCache 의 Object 변경 시 field level 의 변경 사항만을 복제 Buddy Replication & Data Gravitation for HTTP Session 상태 정보를 하나 이상의 buddy node (backup server) 에만 복제 HTTP 요청이 오면 해당 노드는 cluster 에서 상태 정보를 복제 Failover 일 경우, HTTP 요청이 반드시 buddy node 로 전달되지는 않음 Sticky load-balancing (session affinity) 사용 Synchronous VS. Asynchronous 상태 복제를 동기화할 경우, 노드 장애 시 항상 상태 정보를 최신 으로 유지할 수 있으나 성능은 떨어짐 어느 정도의 상태 정보 손실이 발생해도 문제가 없다면 상태 정보 복제를 비동기화해서 성능을 개선 ( 동기화 주기 설정 가능 ) 5
