Environment win7 (64) + Python 2.7.5 + cx_Oracle-5.1.3-11g.win-amd64-py2.7

1. Dll is not a valid win32 application

Run the error "dll is not a valid win32 application" after import cx_Oracle

After investigation, it is found that the client of ORACLE uses 32-bit. After installing the 64-bit client, the OCI.DLL in the directory will be installed.

Just copy a copy of the large Python lib/libsite-packages directory.

2 、 InterfaceError: Unable to acquire Oracle environment handle

After searching on the Internet for a long time, most of them said that they wanted to set ORACLE_HOME, but after looking at the environment variables, they found that there was already a client in PATH.

Path ah, and then remove the OCI.DLL from the libsite-packages, resulting in OK!
