Anyone knows how to check and open port # 1159 at the RedHat 5.5
Enterprise 64-bit server? We need to open up this port for Oracle
Enterprise Manager.

The port is defined in /etc/services file as :
:
:
oracle-oms 1159/tcp # Oracle OMS
oracle-oms 1159/udp # Oracle OMS


However, when we tried "telnet" or "netstat -an" port 1159, we are
getting no good result :

# netstat -an | grep 1159
#

# telnet 170.23.xx.yyy 1159
Trying 170.23.xx.yyy
telnet: connect to address : 170.23.xx.yyy Connection refused
telnet: Unable to connect to remote host: Connection refused


Any idea how to resolve this issue and enable 1159 again ?

Thanks, Bill

Try this as root

lsof -i @`hostname -f`:1159

(Or replace `hostname -f` with the IP address of the host.)

Is 170.23.xx.yyy running a firewall? If so, you might need
to tell the firewall to allow traffic to port 1159.

Port is open, but service is not enable.
Even if you have a firewall blocking your 1159 port, netstat must see a
LISTEN 1159 if the service is running and waiting for incoming connection.
If there is nothing, your oracle service is not even started?
