native library 사용을 위한 LIBPATH 나 java.library.path 설정이 잘 안먹는 경우

1. WAS 버전 : IBM WAS All

2. OS : AIX

3. Error 발생 시점 : OS 변수로 native library 사용을 위한 LIBPATH 나 java.library.path 설정을 했는데 library 를 로드하지 못하고
                           Exception 발생

4. Error message :

5. 예상 이유 :
  OS 설정을 통해 native library 옵션의 경우 전체 Cell 의 재시작이 필요하나 제대로 전체 Cell 이 재시작이 안된것으로 보임
  or 다른 이유

6. 조치 방안:
  WAS 콘솔에서 OS 환경변수를 설정하는 방식을 이용
  Application servers > testServer > Process definition > Environment Entries 메뉴는 OS 변수를 WAS 차원에서 설정할 수 있는
  메뉴를 제공합니다. 해당 메뉴에서 하단과 같이 LIBPATH 를 정의
 
  LIBPATH /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/scp.....
