WebSphere Installation - Port 80 is Not Avaialbe


while installing Maximo/WebSphere, you may encounter an issue with Availability of Port (mostly Port 80).

Resolution:

Generic about checking Port Availability:

To check which all ports are being used, run this on command prompt (in windows):
         netstat -an
Output of above command will show all the ports which are in use.

To check a specific port (e.g. Port 80), run the following command (in windows):
         netstat -an | find "port_number"
         netstat -an | find "80"
If above command returns any output, that means port is in us.
If above command doesn't return any output, Port is Free, and can be used.

Work Around for WebSphere Port 80 Issue:

Go to Administrative Tools in Windows
Open Internet Information Services (IIS) Manager
Expand Server Node (Host Name) on the left panel
Expand Sites
Click on Default Web Site
On right panel, click on Bindings
New window will open with List of Bindings, select http, click on Edit button
Change Port from 80 to 8080, click Ok, click Close
Select Server Node (Host Name) on the left panel again and click on Restart Server from the right panel to restart IIS Server,
No reboot is required.

Now you can proceed with the Installation, error should be resolved.


CTGIN8247E: Required Hostname: System hostname is not fully qualified


while Installing WebSphere, you may encounter this issue of Hostname qualifier.

WebSphere installation requires fully qualified hostname which means it should have a DNS entry or domain name i.e. .com after the hostname (computer name).

Workaround:

  1. Go to Computer Properties
  2. You will see a link Change Settings in front of Compute Name (admin access required here)
  3. In the Properties window, you will see a button called Change...,click that
  4. Below the Computer name, you will see another button called More..., click that
  5. This is the place where you give DNS Suffix which makes your Computer Name as Fully Qualified Hostname.
  6. Type com (no dot symbol)
  7. It will require a Reboot/Restart
