After you installed Oracle, did you run the $ORACLE_HOME/root.sh script as the root user? If after running this script, you still have a problem, then do the following:
cd $ORACLE_HOME/bin ls -l oracle
Your permissions should appear as follows:
-rwsr-s--x 61M Jun 21 2005 oracle
If not, then issue the following as 'oracle':
chmod 6751 oracle
