안녕하세요.
‘수상한 김토끼’ 입니다.
6장의 코히어런스 세션그리드 서비스 – 2(https://with-kami.duckdns.org/oracle-fusion-middleare/coherence/119)를 통해 별도의 코히어런스를 활용한 웹로직 – 코히어런스 세션 클러스터링을 확인 해 보았습니다.
이번 장에서는 6장에서 활용한 유니캐스트가 아닌 멀티캐스트 방식으로 같은 기능을 구현하는 내용을 정리하게 되었는데요, 클라우드 환경에서 해당 아키텍처를 구현하는 과정에서 클라우드 특성상 유니캐스트 방식은 허용되지 않아 또 다른 클러스터 구성 방식인 멀티캐스트 WKA (Well Known Address)을 활용하여 구현 해 보았습니다.
WKA (Well Known Address)를 사용하는 만큼 이를 검증하기 위해 코히어런스와 웹로직 서버를 분리하여 각각의 IP를 가진 서버들 간의 클러스터로 구성되었음을 알려 드립니다.
이 구성을 응용하면 (코히어런스 + 톰캣), (코히어런스 + 웹로직 + 톰캣)등의 구성에도 적용이 가능하며 비용이 저렴한 (웹로직 스탠다드 라이선스 + 코히어런스 라이선스) 조합으로 웹로직 엔터프라이즈 라이선스에서 제공되는 코히어런스 기반 세션 클러스터링 적용이 가능합니다.
이 블로그 글은 미들웨어 경험이 없으신 분들도 쉽게 따라 하실 수 있도록 쉽게 작성하는 것이 목표입니다.
설명을 보고 진행하시다가 궁금하신 내용은 댓글로 문의하시면 가능한 범위 내에서 알려 드리도록 하겠습니다.
1. 코히어런스 설정 변경
6장과 동일한 방식으로 코히어런스와 웹로직을 구성한 후 설정부분만 다음과 같이 변경하여 적용하면 멀티캐스트(WKA)방식 적용이 가능합니다.
우선 멀티캐스트 관련 설정을 위해 JAVA_OPT를 수정 해 줍니다.
위 cache-server.sh 파일에서 설정에 맞도록 수정해야 하는 부분은 크게 3부분으로 아래 스크린샷에서 확인하실 수 있습니다.
# 추가 항목 : 멀티캐스트 관련 설정
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.localport=9000" : 코히어런스 클러스터의 Listen Port
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.localhost=10.0.0.58" : 코히어런스 클러스터의 Listen IP
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.wka=10.0.0.58" : 클러스터에 속할 서버들의 IP, 여러대는 wka2, wka3등으로 구분하여 추가
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.wka2=10.0.0.227"
# 제거 항목 : 유니캐스트 관련 설정
#JAVA_OPTS="${JAVA_OPTS} -Dcoherence.clusteraddress=224.2.1.2"
#JAVA_OPTS="${JAVA_OPTS} -Dcoherence.clusterport=14199"
#JAVA_OPTS="${JAVA_OPTS} -Dcoherence.ttl=1"
# 예제에서 10.0.0.58은 코히어런스 서버, 10.0.0.227은 웹로직 서버이며, 이와 같이 구성하면 10.0.0.58:9000 으로 코히어런스 서버가 동작하게 됩니다.rum.xml의 나머지 부분은 멀티캐스트 WKA 구성과는 관련이 없으며, 필요에 따라 수정하시면 됩니다.
run.xml이 오버라이드 되도록 cache-server.sh 파일도 아래와 같이 수정이 필요합니다.

$JAVAEXEC -server -showversion -cp "$COHERENCE_HOME/lib/coherence.jar:${COHERENCE_HOME}/lib/coherence-web.jar" $JAVA_OPTS com.tangosol.net.DefaultCacheServer $1
수정이 완료 되면 cache-server.sh 파일을 실행하여 코히어런스 서버를 기동시켜 줍니다.
