5장. WebLogic - Coherence 세션 그리드 서비스 - 1

안녕하세요.

'수상한 김토끼' 입니다.

4장의 예제 소스코드 분석을 통해 코히어런스의 동작방식을 확인 해 보았습니다.

5장에서는 코히어런스의 가장 대표적인 기능인 웹로직 - 코히어런스 세션그리드 서비스를 구성해 보고

알아가는 시간을 갖도록 하겠습니다.

 

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

웹로직 - 코히어런스 세션그리드 서비스를 구현하기 위해 가장 먼저 웹로직 서버를 설치해야 합니다.

웹로직 14c를 설치시 포함되어 되어 있는 코히어런스를 사용할 수 있습니다. (Enterprise 라이센스 필요)

 

앞장에서 코히어런스를 단독 설치하여 사용하는 방법을 설명하였습니다만

5장에서는 일반적으로 가장 많이 사용되는 웹로직 도메인을 통해 관리되는 내용에 대한 설명으로

웹로직 설치 후 진행이 필요합니다.

 

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 3개 생성 해 줍니다.

Server-1, Server-2, Server-Coherence 3개의 서버를 생성하였습니다.

 

3.2 서버에서 NodeManager를 실행하여 시스템을 등록 해 줍니다.

NodeManager 설정을 변경해야 하기 때문에 최초 1회 %DOMAIN_HOME/bin 경로에서

startNodeManager.sh 파일을 통해 NodeManager를 실행 후 종료합니다.

NodeManager 실행이 완료되면 웹로직 콘솔로 돌아와 시스템을 구성 해 줍니다.

변경한 NodeManager 설정과 같이 변경해 줍니다.

NodeManager가 기동되고 설정변경이 완료된 경우 아래와 같은 '연결 가능' 상태 확인이 가능합니다.

 

시스템 구성이 완료되면 생성된 서버의 시스템을 변경합니다.

서버에 시스템 변경이 완료되면 서버를 기동해 줍니다.

4. 코히어런스 클러스터 생성

Admin 콘솔 환경 Coherence 클러스터에서 새로 만들기를 선택해 새로운 코히어런스 클러스터를 생성 해 줍니다.

클러스터링 모드는 '유니캐스트'와 '멀티캐스트' 사용이 가능하며, 예제에서는 멀티캐스트를 선택하였습니다.

 

해당 코히어런스 클러스터 멤버로 선택할 서버를 선택 해 줍니다.

 

코히어런스 클러스터가 완성 되었습니다.

 

코히어런스의 저장소 역할을 수행하는 멤버의 설정을 변경 해 줍니다. 예제에서는 Server-Coherence를 대상으로 하며

Server-Coherence를 선택해 구성 탭의 Coherence 하위 탭을 선택 해 다음의 두 저장 영역 설정을 활성화 해 줍니다.

• 로컬 저장 영역이 사용으로 설정됨(Local Storage Enabled)
• Coherence 웹 로컬 저장 영역이 사용으로 설정됨(Coherence Web Local Storage Enabled)

나머지 2개 서버는 앞서 설정한 저장영역을 해제해 줍니다.

5. 코히어런스 클러스터 확인

구성된 클러스터 멤버를 실행하면 로그상에서 코히어런스 클러스터와 관련한 메시지를 확인할 수 있습니다.

동일 클러스터 간에 웹로직이 실행되는 것만으로도 간단히 코히어런스 클러스터의 멤버로 추가되며,

로그에는 코히어런스의 버전 정보와 라이선스, 수행 모드, 코히어런스 클러스터 주소와 포트,

멤버 정보, 멤버 상태 등의 정보가 표시됩니다.

이렇게 웹로직 세션클러스터링을 사용하지 않고 코히어런스를 사용한 세션 구성이 완료 되었습니다.

 

웹로직 세션클러스터링은 Enterprise 라이선스가 필요하지만 웹로직 Standard + 코히어런스를 통해

위와 같은 방식으로 동일한 기능을 구현할 수 있습니다.

 

코히어런스는 클라우드 시대 MSA 아키텍처 등에서 세션공유 이슈 등에 대처가 가능한 훌륭한 솔루션이라고 보이네요.

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

 

여기까지 마무리 하고 다음 장에서는 코히어런스 세션그리드 2(코히어런스와 웹로직 클러스터를 별도 프로세스로 구성)에 대해 알아보도록 하겠습니다.
