need help - Freeradius + oracle

Hello all My setup has freeradius 1.1.0 with Oracle10 my oraclesql.conf file has the following line: readclients=yes Now my problem is: when I change the shared secret stored in nas table, it is not being picked by the RADIUS server. I need to restart the RADIUS server for new shared secret to take effect. Is there now way the RADIUS server can pick it up every time this value changes? Any help would be extremely helpful. -vishwa.
