It depends on, which 9i product you are trying to install - 9i RDBMS, 9i Client, 9i AS or 9i DS.

For 9i RDBMS - you need the Oracle Server, Networking, SqL*PLus (if you need it) and ODBC/JDBC drivers if you want to use them.

Most of the components have dependency checking so if you try to remove something which is need it - you will get an error messages.


Hope that helps,
