at which sqlplus it says
no sqlplus in /usr/sbin /opt/java1.4/bin /usr/dt/bin /usr/bin / /usr/local/bin /
var/opt /usr/css/bin /usr/ucb /etc /bin /opt/bin .

so i suppose i haven't set my path to include the directory where it lies.
the path installed is /usr/oracle/u01/8.1.7/bin
what do i have to write to set my path to include this directory?
thank you vbe
