[WebLogic][Admin Console] 서버 기동/중지 기능을 위한 노드매니저(Node Manager) 구성










실습환경
 - OS: OracleLinux 5
 - WebLogic ver: 10.3.6



해당 작업은 구성요소중에 노드매니저에 해당된다.





노드매니저(Node Manager)란?


 - 웹로직에서 제공하는 유틸리티 (웹로직의 시스템과 연계되는 관리자)
 - 어드민서버와 연동하여 매니지드서버에 기동/중지/재기동 명령을 전달가능





노드매니저 구성 시 Admin Console 에서 매니지드서버의 기동/중지를 컨트롤 할 수 있다.
노드매니저 구성없이 어드민서버에서 기동을 하려 할 시 아래와 같이 보여진다.
(v10.3.6 에서 중지기능은 노드매니저 구성없이 작동 확인)
1004lucifer
선택된 모든 서버는 현재 이 작업과 호환되지 않는 상태이거나 실행 중인 노드 관리자와 연관되어 있지 않습니다. 또는 요청된 작업을 수행할 권한이 없습니다. 작업이 수행되지 않습니다.





작업 순서는 아래와 같다.

1. 리눅스콘솔
  - 노드매니저 구성
2. 어드민서버
  - 시스템생성
  - 시스템에 관리서버(인스턴스서버) 추가
  - 관리서버 기동


1. 노드매니저 구성

2. 어드민콘솔과 노드매니전 연동


- 시스템생성



기본 수신포트는 5556, 위에서 노드매니저 구성 시 설정파일에서 변경이 가능하다.



- 관리서버(매니지드서버) 추가


관리할 매니지드서버(인스턴스서버) 추가

추가된 관리서버 확인

'모니터링 - 노드관리자상태' 항목에서 '연결가능' 상태 확인



- 매니지드서버 노드매니저 구동설정 (옵션/권장)
'구성-서버시작' 항목에서 PermSize 옵션 줄것을 권장
(v10.3.6 에서 PermSize 옵션 없을 시 OOME 에러 발생 - 링크)




- 매니지드서버 컨트롤(기동/중지) 확인








- 프로세스 확인
