Two issues with Python connecting Oracle data

Environment Win7 (+) + Python 2.7.5 +cx_oracle-5.1.3-11g.win-amd64-py2.7

1. dll is not a valid Win32 application

Import cx_oracle after running an error "DLL is not a valid Win32 application"

After finding out that Oracle's client is using a 32-bit, 64-bit client, the OCI.DLL in the directory will be installed

Copy a copy of the market Python lib/libsite-packages directory.

2, interfaceerror:unable to acquire Oracle environment handle

On the internet for a long time mostly said to set up Oracle_home, but after looking at the environment variables found in the path has a client

The path is gone, and then the OCI.DLL is removed from the libsite-packages, and the result ok!
