[cx-oracle-users] Full version info of cx_Oracle installed

[Robert <web...@gm...>]

Oracle Server: 11g
Client@Win7 : Instant Client 10g
Python: v  2.7

>>> cx_Oracle.clientversion()
(10, 2, 0, 5, 0)
>>> cx_Oracle.buildtime
'Mar 19 2011 23:12:21'
>>> cx_Oracle.apilevel
'2.0'

Got this error:

>>> db = cx_Oracle.connect(OraUid + "/" + OraPwd + "@" + OraService)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
cx_Oracle.DatabaseError: ORA-24315: illegal attribute type


I think it is because I installed the 11g version of cx_Oracle
(cx_Oracle-5.1-11g.win32-py2.7.msi)

so 2 questions:
1) How to verify the exact version/edition of cx_Oracle installed ?
2)  Can I just install this : cx_Oracle-5.1-10g.win32-py2.7.msi  or
should I uninstall the existing version ?

Thanks
robert
