OK, for what its worth, I downloaded Oracle 9i over (I think my first DL 
was bad) burned it, took it home, and tried to install it last night. 
 After twiddling with gencliensh to build libclientsh.so (of which I am 
not sure what I did was CORRECT) I finally got a 9i database up on 
RedHat 7.1.

I was able to reproduce your problem, mostly.   What I found was that 
any array based executemany() was failing one way, and the dynamic fetch 
mode was failing with the error "arrays can only be bound to PL/SQL 
statments" which is a sort of "aha!" because it generally implies the 
binding arguments are being interpreted differently.

Sadly, it took so long to do most of the above I didnt have much time 
left to do much analysis.
