A pre-requisite for installing OBIEE 11g is configuring a Loopback Adapter. The Loop back adapter assigns the system(server) a Static IP. If a static address is not assigned there will be issues in starting OPMN services, should the IP change for some reason. Give below are the steps for configuring the loop back adapter on a Windows 32 bit system :
3. Setting up the Static IP
a. Click Start and click on Control Panel
b. Click and open Network and Sharing center
c. Click on Change adapter Settings on the left pane?
d. Select the newly created Microsoft Loopback Adapter (can be identified from the 3rd line text)
e. Right Click and click Properties
f. Select Internet Protocol Version 4(TCP/IPv4) and click on Properties button
g. Select “Use the following IP address” and specify the IP address to be used. Oracle recommends the following non-routable addresses
· IP Address: 10.10.10.10 or 192.168.x.x (x is any value between 0 and 255)
· Subnet mask: Enter 255.255.255.0
· Leave all the other fields empty
4. Adding the IP to the Hosts File
a. Open Windows Explorer
b. Navigate to the Windows directory (generally “C:\Windows\System32\drivers\etc)
c. Double Click to Open the Hosts File
d. In the end, add the Static IP used in step 3g along with Machine and domain name
Format:
Loopback_adapter hostname.domainname hostname
ex: 10.10.10.10 mycomputer.mydomain.com mycomputer
