This is the answer that I have received so far:

Hi Paul,

Thanks for passing this along to us.

We are testing TDP Oracle 2.2.0 with Oracle 9i/9.0.x as Oracle ships their
products.  The different platforms are coming out at different times. As
they are tested, we will update the Web site. So far I am aware that we can
certify the Oracle 9i works on HP 64 bit and Solaris 32 bit.
Watch this web page
http://www.tivoli.com/support/storage_mgr/tdp_oracle.html as the other
platforms are certified.
