반응형
- 해당 설정은 WEB 서버 앞 단에 L4, L7, ALB 등에서 호출을 할 때 응답을 받는 과정에서 getHostName을 정상적으로 받아오지 못하는 경우 발생한다.
- JEUS 에서는 옵션을 통해 DNS를 통해 Hostname을 가져올지 안 가져올지 설정하여 이 문제를 해결할 수 있다.
기본값 true > false 로 변경
- jeus.servlet.request.enableDns 설정에 대한 설명
- ServletReqeust.getRemoteHost()를 호출할 때 DNS를 통해서 호스트명을 얻어올지 여부를 설정한다. 웹 엔진이 있는 서버의 DNS 접근 여부를 설정하는 것이므로 웹 엔진 레벨 프로퍼티로 제공한다.(기본값 true)
아래 로그가 발생할 경우 해당 상황을 유추 할 수 있다. (지연 중일 때 Thread dump 로 확인)

- JEUS Webadmin JVM 옵션에 -Djeus.servlet.request.enableDns=false 를 넣고 MS 재 기동 해주면 된다.
