Many Oracle products such as Database Control, Database Listener, Weblogic Server either standalone or bundled in JDeveloper use the machine IP address and or host name during the installation and may fail to function properly when either changes. This document will detail the setup and configuration on Windows hosts in particular this install was done on Windows 7 Ultimate. Click the Next button to continue.

Once the installation is complete click the Finish button to exit the Add Hardware Wizard. Now we need to configure the adapter.

Click the Change adapter settings on the left hand side of the panel. Right click the adapter and select properties. Care should be taken when choosing your address that it is also not in the same address range as your work or home network settings. Once you have entered the IP information click the OK button to continue. You will be taken back to the Properties page for the Local Area Connection, click the Close button to finalize the changes.

The last thing we need to do to complete this to add an entry to the hosts file. Back in the command prompt that was opened as the administrator bring up Notepad like below.

Add a line at the bottom that includes the IP address you added for the Loopback Adapter along with the name of the machine. Once you are done, save and exit notepad. With all of that complete you should now be able to ping by name successfully. Having the Loopback Adapter installed and configured on a machine that used DHCP prior to installing Oracle products will save you a lot of headache when the IP or host name of the machine changes when you change networks.

The steps are the same if you are using your Home WiFi setup. Record the values you entered, which you need later in this procedure. Leave all other fields empty. Click OK. Click Close. Close Network Connections.

Restart the computer. For example:
