Note: I would never run exp/imp using different versions than the server and I usually do this using the same Oracle Home on the database server. Anyway, we may be violating some "official" certifications (not sure about this?), but I have yet to see ANY client version that cannot connect and WORK against ANY server version (at least between version 6 to version 9), except for the old SqlNet V1 that was dropped back in 7.3 ? or 7.2 . The client version always seems to be the older version (in our shop), but we definitely have cases where newer client versions are hitting older server versions. It always seems to work ok. Also, we completely skipped 8.0.x versions and went from 7.3.4 to 8.1.6 back in 2000. -- "Christoph Kukulies" wrote in message news:bor0n0$sdk$1@nets3.rz.RWTH-Aachen.DE... > Are there any restrictions or rules which server versions can work with what > client versions of Oracle? > > Can a 8.0.5 client connect to a 9i server? > Can a 9.2 client connect to a 8.0.5 server? > > -- > Chris Christoph P.
