[WebLogic][Error] 노드매니저로 서버 기동 후 발생한 PermGen OOME 에러










실습환경
 - OS: OracleLinux 5
 - WebLogic ver: 10.3.6



증상

노드매니저 구성 후 처음으로 매니지드서버를 기동했는데 웹페이지에서 계속 로딩중 표시만 나오며 Response 를 받아오지 못하고 있었다.

로그를 보니 아래와 같이 PermGen space OOME(Out Of Memory Error) 가 발생을 했다.
단순 web.xml 파일과 index.jsp 파일 하나있는 소스인데 이게 발생을 할 수 있나 싶었는데..
PermGen 용량을 지정해주니 문제가 해결이 되었다.

조치방법
1004lucifer
'서버요약-서버선택' => '구성-서버시작'
위의 항목에서 인수에 아래와 같이 PermGen 크기를 지정해준다.
-XX:PermSize=128m -XX:MaxPermSize=256m






위와같이 지정 후 노드매니저를 통해 어드민서버에서 매니지드서버를 재기동하면 정상적으로 웹페이지가 보여진다.
