Hi:

I just installed Oracle 9.0.1 on a RedHat 7.2 linux box. The installation
was successful and I let the installer to create a "generic" database
(including the configuration of listener.ora and tnsnames.ora, etc) for me.

However when I bounced the listener, I got listener "status UNKNOWN" message
(see below). I can still use "sqlplus system/[Email Address Removed] to connect
without problem. This suggests that the listener is running fine. So my
question is: What does this status "UNKNOWN" mean?

TIA.

Guang
