Answer 1

Need a solution as well.

I have the same setup on WinXP (Apache 2.2.21/ mod_wsgi 3.3/ python 2.7.2/ cx_Oracle 5.xx). I found that cx_Oracle 5.1 also fails with the same error. Only 5.0.4 works.

Here is the list of changes that were made from 5.0.4 to 5.1:

1. Remove support for UNICODE mode and permit Unicode to be passed through in everywhere a string may be passed in. This means that strings will be passed through to Oracle using the value of the NLS_LANG environment variable in Python 3.x as well. Doing this eliminated a bunch of problems that were discovered by using UNICODE mode and also removed an unnecessary restriction in Python 2.x that Unicode could not be used in connect strings or SQL statements, for example.
2. Added support for creating an empty object variable via a named type, the first step to adding full object support.
3. Added support for Python 3.2.
4. Account for lib64 used on x86_64 systems. Thanks to Alex Wood for supplying the patch.
5. Clear up potential problems when calling cursor.close() ahead of the cursor being freed by going out of scope.
6. Avoid compilation difficulties on AIX5 as OCIPing does not appear to be available on that platform under Oracle 10g Release 2. Thanks to Pierre-Yves Fontaniere for the patch.
7. Free temporary LOBs prior to each fetch in order to avoid leaking them. Thanks to Uwe Hoffmann for the initial patch.
