I notice that when I rebooted my Solaris 8 machine with Oracle 9.0.1 the listener and Oracle can be started automatically. I have 2 instances. However, the listener.ora file is nowhere to be found. After I stop one of the listener for 1 of the 2 instances, I cannot start back. I enter -> 'lsnrctl start pro2'. Whas has happened? The listener is started after rebooting the machine but I cannot start it manually. Please help. Tks.
