Oracle10g on LinuxxFedora 2) - SQLPLUS Problem

I seemed to have installed Oracle 10g R! on Linux Fedor Core 2 successfully. However, whn I siwtch directories to $cd ORACLE_HOME/bin and type $sqlplus I just get another $prompt, no SQL> promt (and no error message). A starter database was not installed, if that maters. Any clues about why this is happening would be much appreicated. Thanks! Received on Fri Oct 13 2006 - 22:03:19 CDT
