The reason you are getting that error is that the version of cx_Oracle
that is current only supports Oracle 8.1.x and above. Oracle has long
since dropped support for Oracle 8.0.x and so I dropped support for it
as well. If you absolutely must continue using 8.0.x with all of its
bugs (8.1.7 and 9.2.0 are much more stable) then I can provide you with
the source for the last version that supported 8.0.x or I can tell you
which source needs to be changed to support 8.0.x. Let me know. Thanks.
