Hi Guys,

Thought I'd start off fresh with a new discussion. When last we spoke, I was having issues with connecting to Oracle through the browser: http://localhost:8080/apex.

These issues were so difficult and frustrating to rectify I decided to uninstall Oracle Express from my computer and today decided to install it on a different computer on the network.

This time, I have some success. On that new "host" computer I am able to connect via SQL Developer and the browser using URL: http://localhost:8080/apex

So far so good. Now, I wanted to see if I could connect from my original computer, this time using the IP address that points to the host computer: http://192.168.2.16:8080/apex

This is the response:

The connection has timed out
The server at 192.168.2.16 is taking too long to respond.

I'm thinking this is more of a Windows network configuration thing. Obviously, if I go to the host computer I'm able to connect locally, but something is preventing me from connecting from anywhere on the network. Are you able to assist on troubleshooting this? Fortunately, on the host computer I do finally have access to the Firewall. The thing is, I don't want to muck around in there without some instruction because I don't know what I'm doing in there. I'm running Windows 7 on both computers.

Alan

when localhost is used, then no remote client can ever connect to this system/db/listener
localhost only ever uses 127.0.0.1; which is a non-routable IP#

There must be a way to allow connection from somewhere on the network other than locally. Maybe there's a script that needs to be edited? Otherwise, what's the point of having a database you can't connect to remotely?

Yes, don't use localhost.
Any DB Server should have a static & routeable IP# assigned to it.

Right! The host computer does have an IP assigned to it: 192.168.2.16

So, I should be able to connect using: http://192.168.2.16:8080/apex

That should work, but it doesn't.

You want me to run these commands on my computer or the computer that is hosting Oracle?

Hi, man. Run the telnet test! On the old PC,
telnet 192.168.2.16 8080
and if you don't get through to the blinking cursor, you have a networking problem - possibly firewall related. Remember that ping doesn't test tcp connectivity, only IP (or something like that).

Ok. so now we're back to the firewall thing. I am able to get into the firewall on the computer running Oracle. Is there something specific you want me to look for in there?

I'll have to continue this conversation tomorrow. I'm out for the rest of the day. I'll be in touch tomorrow.

Ok guys,

I'm back. What's the next step? How do we figure out what's blocking the connection from my computer to the host computer running Oracle?

Alan
