6장. WebLogic - Coherence 세션 그리드 서비스 - 2

안녕하세요.

'수상한 김토끼' 입니다.

5장의 코히어런스 세션그리드 서비스 - 1을 통해 코히어런스 기반 세션 클러스터링을 확인 해 보았습니다.

6장에서는 별도의 코히어런스를 활용하여 웹로직 - 코히어런스 세션그리드 서비스를 구성해 보고

알아가는 시간을 갖도록 하겠습니다.

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. 웹로직 14c 설치

6장에서는 웹로직, 코히어런스를 활용하여 세션 클러스터링을 구현하기 때문에 웹로직 서버를 사용하였습니다.

이 방법을 사용하면 웹로직 스탠다드 라이선스에서도 엔터프라이즈 라이선스에서 제공되는 코히어런스 기반

세션 클러스터링 적용이 가능합니다.

 

예제에서는 웹로직을 사용하였지만 이기종 WAS에도 적용이 가능함으로 (코히어런스 + 톰캣)과 같은 구성도

적용이 가능합니다만 본 예제에서는 다루지 않겠습니다.

(이기종 WAS에서도 JVM 옵션 및 WAS 세션설정변경 등으로 동일한 구성가능)

 

웹로직 설치는 이번 페이지에서는 상세히 다루지는 않겠습니다. 웹로직14c 설치관련 내용이 필요하신 분은

관련 내용이 잘 정리된 '와스고수'님 블로그를 참조하여 설치를 진행 해 주세요.

2. 웹로직 Admin 서버 접속

서버 설치가 완료되면 startWebLogic.sh 스크립트를 사용하여 Admin 서버를 기동 해 줍니다.

Admin 서버가 기동되면 http://서버주소:7001/console 주소로 접속합니다.

도메인 구성할때 입력한 '사용자이름'과 '비밀번호'를 입력하고 로그인하면 Admin 콘솔을 확인할 수 있습니다.

3. 클러스터 설정을 위한 서버 생성

3.1 클러스터 설정을 위해 웹로직 서버 인스턴스를 2개 생성 해 줍니다.

Server-1, Server-2 2개의 서버를 생성하였습니다.

 

NodeManager 구성 및 서버 생성 상세내용은 5장의 3. 클러스터 설정을 위한 서버 생성을 참고해 주세요.

중복되는 내용으로 6장에서는 다루지 않겠습니다.

4. 코히어런스 클러스터 설정변경 (cache-server.sh 파일 수정)

별도 코히어런스 프로세스를 사용하여 세션 클러스트링을 사용하기 위한 코히어런스 설정 변경이 필요합니다.

외부 코히어런스를 사용하여 웹로직 세션 클러스터링을 구성하기 위해서는 JAVA_OPTS 부분과 -cp(클래스 패스)부분

에 대한 수정이 필요하며, 추가 항목은 다음과 같습니다.

# 코히어런스 session cache config(default설정, 설정 변경이 필요한 경우 override 하여 사용)
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.cacheconfig=default-session-cache-config.xml"
# 세션객체의 저장소(코히어런스에 저장 true)

# 멀티캐스트 Port
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.clusterport=14199"
# TTL
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.ttl=1"
 
# cp에 coherence-web.jar 파일 추가
$JAVAEXEC -server -showversion -cp "$COHERENCE_HOME/lib/coherence.jar:${COHERENCE_HOME}/lib/coherence-web.jar:" $JAVA_OPTS com.tangosol.net.DefaultCacheServer $1

default-session-cache-config.xml 파일 수정이 필요한 경우 override 파일을 작성하여 파일경로를 변경 해 주시면 되며

default-session-cache-config.xml 파일내용은 다음과 같습니다.

세션 공유를 위한 코히어런스 설정이 마무리 되었습니다.

5. 웹로직(WAS) 설정변경 (JAVA_OPTS 내용추가, weblogic.xml 파일 수정)

 

5.1 startManagedServer.sh 파일 수정

웹로직 기동 스크립트(startManagedServer.sh 파일)에 코히어런스 관련 JAVA_OPTS 다음 내용을 추가 해 줍니다.

JAVA_OPTS="${JAVA_OPTS} -Dcoherence.cacheconfig=default-session-cache-config.xml"
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.session.localstorage=true"
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.cluster=my_cluster"
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.clusteraddress=224.2.1.2"
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.clusterport=14199"
JAVA_OPTS="${JAVA_OPTS} -Dcoherence.ttl=1"
JAVA_OPTS="${JAVA_OPTS} -Djava.net.preferIPv4Stack=true "
 
USER_MEM_ARGS="${MEMORY} ${GC} ${ANALYSIS} ${BOOT_PROPERTIES} ${ETC_OPT} ${JAVA_OPTS}"

코히어런스와 동일한 JAVA_OPTS를 추가 합니다.

 

추가된 startServer1.sh 파일은 다음과 같습니다. 제가 사용하는 스크립트 파일로 환경에 따라 파일내용은

다를 수 있으니 JAVA_OPTS 부분만 참고하여 적용해 주세요.

[weblogic@coherence script]$ cat startServer1.sh

5.2 weblogic.xml 파일 수정

어플리케이션에서 세션저장위치를 변경하기 위해 세션 클러스터링을 적용하려는 어플리케이션의

$APP_HOME/WEB_INF/weblogic.xml 파일 변경이 필요합니다.

 

JAVA_OPT 변경 후 weblogic.xml 파일의 session-descriptor 속성의 persistent-store-type 항목을 수정 해 줍니다.

이렇게 웹로직과 별개로 구성된 코히어런스를 사용한 세션 클러스터링 구성이 완료 되었습니다.

---

7. 코히어런스 Client Application을 통한 모니터링

이렇게 구성된 코히어런스 모니터링은 Client Application을 통해 확인이 가능합니다.

 

$COHERENCE_HOME/bin/coherence.sh 파일을 통해 Client Application에 접근할 수 있으며

웹로직 세션 클러스터링에 사용된 'my_cluster'에 접근하기 위한 설정 변경이 필요합니다.

 

변경내용은 coherence.sh 파일에 cache-server.sh 파일과 같은 내용(JAVA_OPTS, -cp)을 적용해 주면 됩니다.

현재 상태를 모니터링할 수 있으며 'who' 명령 등을 통해 실시간 모니터링이 가능합니다.

여기까지 별도의 코히어런스를 활용하여 웹로직 - 코히어런스 세션그리드 서비스 구성을 완료 하였습니다.

 

웹로직 세션 클러스터링은 Enterprise 라이선스가 필요하지만 위와 같이 구성하면

웹로직 Standard 라이선스 + 코히어런스를 통해 위와 같은 방식으로 동일한 기능을 구현할 수 있습니다.

---

코히어런스의 가장 대표적인 사용범위인 만큼 필요한 분들은 꼭 실습을 통해 관련 내용을 확인해 보시기 바랍니다.

 

여기까지 마무리 하고 다음 장에서는 코히어런스 JMX 기반 모니터링에 대해 알아보도록 하겠습니다.
