I am having a problem with cx_Oracle module for Python:
I have multiple Oracle Clients installed. I am only interested in accessing the 10g with Python.
I'm running Python 2.7.2 (python-2.7.2.msi)
I've installed cx_Oracle for Python 2.7 and Oracle 10g (cx_Oracle-5.1.1-10g.win32-py2.7.msi)
I thought placing the 10g path at the front of the PATH would fix my problem.
My last check is to verify the %PATH% environment setting is changed via Control Panel > System > Advanced system settings... curses my company has me locked out!!!
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
ImportError: DLL load failed: The specified procedure could not be found.
c:\Oracle\10g\FullClient\bin;C:\Program Files\Oracle\jre\1.1.7\bin\;C:\Oracle\8.0\jdk\bin\;C:\Oracle\8i\bin\;C:\Oracle\8.0\BIN\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Program Files\Windows Imaging\;C:\Program Files\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Common Files\Roxio Shared\10.0\DLLShared\;C:\Program Files\ActivIdentity\SecureLogin\;C:\Oracle\10g\FullClient\bin\;C:\Program Files\Axalto\Access Client\v5\;C:\Program Files\1E\SMSNomad
I recall that to get Python talking to Oracle on my personal laptop I needed to install Oracle Instant Client.
I’m not sure if that is required.
Any ideas would be much appreciated,

Not experienced with the windows implementation, only on linux ... but maybe it may help ...
cx_Oracle is only the bridge between python and the oci interfaces of Oracle, an exposure of the c-api's towards python.
On linux you must set the LD_LIBRARY_PATH variable to the location where the oracle client libraries can be found. (typically something linke libclntsh.so.*). So ... I guess that on a windows environment the client dll's should be in the path (%PATH%) ... Hope somebody can confirm or correct this. Maybe it may help ...
