I've not had the (dis)pleasure of running an oracle db so I can't say
exactly. All I can do is point you in a direction that makes sense.
First thing is to double check that iptables is not interfering.
"service iptables off". Second, there is probably a config file for
the db that acts as a master control, for mysql it's /etc/my.cnf etc.
No clue what it is for oracle, but check it to be sure it's not
blocking anything there. You can always lock it down later. I seem to
recall something about oracle environment variables that have to be
set, and oracle requiring a shell other than /sbin/nologin or
/bin/false. No clue how accurate this is.
