In principle, Oracle versions try to be interoperable.
In practice, a jump of two versions can have problems.

On Oracle support site, I found this statement:
"""
An ORA-3134 error is incorrectly reported if a 10g client tries to
connect to an 8.1.7.3 or lower server
"""
Do you get this error?

You may try to use Oracle 9 client instead.
We have successfully used versions 9.2.0.4 and up to connect to various
databases: 8i, 9i, 10g.

Hope this helps,
