[요약] Coherence 클러스터 멤버 기동/종료 하기

1. 캐시 서버 시작

캐시 서버(com.tangsol.net.DefaultCacheServer)는 캐시된 데이터 저장을 담당하는 클러스터 구성원입니다. 명령어 또는 프로그래밍 방식으로 기동할 수 있습니다.

Java -cp옵션을 사용하여 coherence.jar 보다 먼저 클래스 패스를 설정함으로서 COHERENCE_HOME/config에 있는 tangosol-coherence-override.xml과 coherence-cache-config.xml 파일을 오버라이딩 할 수 있도록 합니다. 

java -server -Xms512m -Xmx512m -cp COHERENCE_HOME\config;COHERENCE_HOME\lib\coherence.jar com.tangosol.net.DefaultCacheServer

맨 뒤의 옵션에 Grid ARchive (GAR)와 <autostart> 옵션 (기본값:5초)을 재설정할 수 있습니다.

기본 로그 내용은 아래와 같습니다.

3. 클러스터 구성원 중지

명령줄에서 또는 프로그래밍 방식으로 클러스터 구성원을 중지할 수 있습니다. 보통 kill 명령어(UNIX계열)와 Ctrl+c(윈도우계열)로 중지를 합니다.

 

4. 롤링 다시 시작 수행

롤링 다시 시작은 다시 시작하는 동안 데이터가 손실되지 않도록 클러스터에서 캐시 서버를 다시 시작하는 기술입니다.
