- 굵게 표시된 설정값을 extenstions, management 엘리먼트 사이에 등록

- 붉게 표시된 값을 조정하면 됨.

slave 구성시 env.sh에서 GC 설정을 하는 것이 재기동시 로그를 재생성 함.

export JAVA_OPTS=" $JAVA_OPTS -XX:+PrintGCTimeStamps "

export JAVA_OPTS=" $JAVA_OPTS -XX:+PrintGCDateStamps "

PrintGCDateStamps로 옵션을 주는것이 일자/시간으로 구분되어 확인하기 편함

- gc 로그 로테이션 설정

-XX:+UseGCLogFileRotation : 지정하면 록그를 로테이션 함

-XX:NumberOfGCLogFiles=5 : 유지할 로그파일 갯수

-XX:GCLogFileSize=128K : 로그파일 크기(최소 8k)

쓰레드 갯수 모니터링하는 방법입니다.

시스템 프로퍼티스에  AJP 커넥션 타임아웃을 추가로 설정해주시기 바랍니다.

JBoss에서 서비스하고 있는 어플리케이션내에서 GET/POST Parameter가

기본 설정값(512)보다 많을 경우 발생합니다.

standalone-ha.xml에 아래의 설정을 넣어주시면 됩니다.

/ces/jboss/server/standalone1/configuration/standalone-ha.xml

standalone-ha.xml 파일 맨 위에 보시면 extensions 엘리먼트와 management 엘리먼트 사이에

굵게 표시된 설정값을 넣어주시면 됩니다.
