check if Port 1801 is free.

check netstat -an | grep 1801

TNS-12618: TNS:versions are incompatible

---this is the status of the listener
pls help

[paragp1981]

some other processes is using your port.

was this listener running previously. if not then change port and try starting the listener.

If yes then find out who is using listener port and should it use that port. if not suppose to use then stop that process and start listener.

To find which process is using port

lsof | grep

[paragp1981]

I think you have 2 different versions OH on same machine.
as you got this error
"TNS-12618: TNS:versions are incompatible"

Most probably you are using small version utility to operate on high version listener.

I found out the problem
there is one 10g database listener in the same machine which is using the same port number.
Where i was trying to restart the listener for 9i database.
