external procedure 를 사용해야 되는데요 ;; 

ORA-28575: unable to open RPC connection to external procedure agent 라는 에러가 발생하네요 . 

google 검색을 해보니. 

$ORACLE_HOME/hs/admin 디렉토리에 extproc.ora 파일 SET EXTPROC_DLLS=ANY 로 수정을 하고. GRID리스너 사용시에는 $GRID_HOME/hs/admin  extproc.ora 파일 SET EXTPROC_DLLS=ANY 로 수정을 하면 된다고 하던데요 ;;

왜 수정을 해줘도 사용을 못할까요 ;;
