Oracle Testing Accessibility

Oracle Database Tips by Donald Burleson

Question:

My requirement is to test the accessibility of the Application hosted on the Appl Server from outside U.A.E.

Current Scenario - I have a private network and my Application server has static IP 150.140.130.41. I have an ADSL line from the ISP in which I put the application server on the internet. A dynamic IP is allocated each time I put the server on the internet. The dynamic IP provided by ISP is not a published IP.

I have tested the accessibility from outside U.A.E. I am able to ping the Server however when trying to access the Application logon web page I get the following error:

Error Message Begin -

(tcp_error)Network Error

A communication error occurred: "Operation timed out"

The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

For assistance, contact your network support team.

Error Message End.

Can you guide me as to what is to be done for me to conduct the testing?

Answer:

I think your issue is the static IP/dynamic IP. Get a little Linksys router and place it between the server and the ADSL modem. The router will handle the dynamic IP. Use DynDNS.org (or another such service) so as the IP changes, it updates and you can access the application with the same domain name. Pass the ports needed through the router firewall to access the application behind the built in firewall.

Hope this helps.
