Listener error

[lyang]

I just update oracle patchset from 92060 to 92080, then got listener error below, any idea?

LSNRCTL> status

your listener is still running

You can do a

ps -ef | grep lsn

to see what listeners are running.

Before apply oracle patch, all oracle processes need to be stopped, how to grep/kill all oracle processes. Databases can be shut down from dbshut, lsnrctl can be stopped manully. What's else?
