opening port 1521

[Elko]

please enable ip tables :)

1 ) check does anything listen on port 1521, guys already described how to do it

2) open port 1521 on redhat 5 use as root

system-config-securitylevel

small window will open, then "other ports " and add port 1521.

Hope this helps

What is the HOST set to the listener.ora file?

Try change it to 172.16.30.230 and restart the listener.
