Lotus Connector for Oracle

We are trying to connect a Domino 7.0 to a Oracle DB using the Lotus Connector for Oracle. I am not sure right now, but I think the connect is done using the LCLSX (not DECS, no LEI). On a Windows Server we had no problem with the software to connect to Oracle, on a SuSE Linux ES 10 we can not get it connected.

Does the Oracle connect require an Oracle client to be installed on Linux Server? If yes, how do I make this client available to the Domio Server?

Is there any install for the basic/free Lotus Connectors? Do they work at all on Linux?

Any help is greaty appreciated!
