원인은 오라클 설치시 지정한 $LD_LIBRARY_PATH 문제이다.

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

profile 이렇게 지정하고 지정하고 사용하는 데, 문제는 오라클 먼저 찾고 나서 그다음 시스템의 경로를 찾는 데, 오라클 라이브러리 경로의 libexpat가 있으니까 이걸로 yum 실행하는 데,

이게 아니라 시스템의 라이브러리 패스를 찾아야 하는 맞게 동작하는 것이다.

export LD_LIBRARY_PATH=/lib64/

위 명령어를 실행 후 하면 제대로 동작한다.
