Scouter JDK 17 이용 시 server 실행 문제

1. Scouter server sh 파일을 jdk 17 로 실행시 오류

 

Scouter 를 사용해보는 과정에서 JDK 17 버전에서 실행이 불가능 한 것을 확인 하였고 해당 문제를 해결 하는 방법을 공유 하고자 함.

 

현재 개발 시 사용중인 jdk 17 에서 scouter\server 경로의 .\startcon.bat(window os에서 실행) 을 실행 시켰을 경우 아래와 같은 에러가 나옴

해당 문제는 agent 실행 시 에는 발생하지 않으나 server 실행은 jdk 1.8 에서만 구동되는 것으로 보임

 

우선 정상적인 실행을 위해선 jdk 1.8을 설치하고 startcon.bat 실행파일 옵션을 jdk 1.8 로 설정해줌.

 

window 에서 파일 수정 시 (powershell 이용)
 
 notepad .\startcon.batBASH

 

위와 같이 startcon.bat 파일을 메모장으로 열어 jdk 1.8 경로를 지정

(기존)
java -Xmx512m -classpath ./scouter-server-boot.jar scouter.boot.Boot ./lib -console

(변경 - jdk 1.8 경로 지정) [ 일반적으로 윈도우에서 jdk 설치 시 위치는 C:\Program Files 에 있음 ]
"C:\Program Files\Eclipse Adoptium\jdk8u412-b08\bin\java" -Xmx1024m -classpath ./scouter-server-boot.jar scouter.boot.Boot ./lib -consoleBASH

 

 

변경 사항 저장 후 다시 실행

 

(현재 경로)
C:\Users\parkk\OneDrive\바탕 화면\scouter-all-2.20.0\scouter\server

(server 패키지에 있는 startcon.bat 을 실행)
.\startcon.batBASH

 

 

정상 실행 시 다음과 같이 로그 마지막에 실행이 된 것을 확인 할 수 있음
