下载:
cx_Oracle下载地址:http://cx-oracle.sourceforge.net/instantclient-basic
下载地址:http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
window环境:
python27 oracle10
需要软件:
cx_Oracle-5.1.2-10g.win32-py2.7.msi
instantclient-basic-win32-10.2.0.4.zip
1. 直接双击msi文件,即安装cx_Oracle;
2. 解压instantclient-basic-win32-10.2.0.4.zip,将得到的.dll文件全部拷贝到F:Python27Libsite-packages目录下
linux环境:
python26 orracle10
需要软件:
cx_Oracle-5.1.2-10g-py26-1.x86_64.rpm
basic-10.2.0.4.0-linux-x86_64.zip
1. rpm -ivh cx_Oracle-5.1.2-10g-py26-1.x86_64.rpm
2. (此处参考http://www.gxlcms.com/)
设置环境变量
vi /root/.bash_profile
增加如下两行:
export ORACLE_HOME=/usr/local/instantclient_10_2 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
运行source /root/.bash_profile使改动生效
建立此链接库的符号链接
cd $ORACLE_HOME ln -s libclntsh.so.x.x libclntsh.so
重新安装cx_Oracle
注意加--nodeps参数,否则还会报上述错误
[root@BJ-UPDATE-01 ~]# rpm -ivh --nodeps cx_Oracle-5.0.1-10g-py24-1.x86_64.rpm
#5.0.3版本不用加--nodeps参数
测试:
#Python >>> import cx_Oracle >>> db = cx_Oracle.connect('user/psw@114.242.113.91:1521/orcl') >>> print db <cx_Oracle.Connection to user@114.242.113.91:1521/orcl> >>> cr=db.cursor() >>> cr.execute("select * from LOGININFO") <__builtin__.OracleCursor on <cx_Oracle.Connection to user@114.242.113.91:1521/orcl>> >>> rs=cr.fetchall() >>> print rs [('40288a8542746fd90142746fdbb50001', 'cccccc', 1, 1, None, None, None), ('40288a85427474b601427474b8270001', 'eeee', 1, 1, None, None, None), ('40288a854273bce0014273bee6310002', 'dddddd', 0, 0, None, None, None), ('40288a854274532d014274532f600001', 'cccccc', 1, 1, None, None, None), ('40288a8542747c750142747c77ac0001', 'eeee', 1, 1, None, None, None), ('40288a8542744fb30142744fb5e90001', 'cccccc', 1, 1, None, None, None)] >>>
