cx_Oracle, Python binding of Oracle

참고정보
python setup.py build 후, 오류메세지가 나오면, 아래 명령을 수행한 뒤 다시 해본다. --from AIX 에 cx_Oracle 설치하기
/usr/local/lib/python2.4/config/ld_so_aix cc_r -pthread -bI:/usr/local/lib/python2.4/config/python.exp build/temp.aix-5.2-2.4/cx_Oracle.o -L/oracle/product/9.2.0/lib32 -lclntsh -o build/lib.aix-5.2-2.4/cx_Oracle.so -s
