This developers question is, with all respect, a bit stupid.

To 'open a port' on your machine you need some sort of server listening
on that port. You can do this by several ways (little Perlscripts,
netcat, grown up applications, ...).
In your case methinks he wants an oracle instance to listen on that port.

On the other hand, it's more likely that he wants to have someone open
that port on a device *between* his and your server, e.g. a firewall, to
let some existing applications talk to each other.

Just my 2 cents

I guess I should be more specific...He would like to be able to ssh or
telnet to port 9003 on the Solaris machine from a Linux machine. Do I
just need to add an entry to /etc/services, something like: ssh
9003/tcp and then one for udp as well?

No, you'd have to run a server and have it use that port.

Which raises the question, why couldn't he just ssh or telnet normally?
What on earth is the deal with 9003?
