원인은 Different version of WebLogic binaries used on the client side to connect to remote WebLogic server.

 

예를 들어, WebLogic 기동은 12.2.1.3 버전으로 기동하고 WebLogic 12.1.3(다른 버전)의 엔진의 binary 파일인 wlst를 실행하여 인스턴스 정보를 가져오려고 할 때 발생하는 에러 메시지 이다.

 

아마 고객사에서 WL_HOME이 엉뚱한 버전의 WL_HOME으로 잡힌 상태에서 wlst 스크립트를 돌려서 발생한 에러이지 싶다.

 

그래서 웬만하면 위와 같은 에러가 발생할 경우 홈 경로를 절대경로로 잡고 실행하는 것이 안전하다고 생각한다.
