In this post, I’ll install a four node OBIEE 10g cluster integrated with Oracle Application Server (for BI Publisher) IIS, and SSO. 
 There will be two “web nodes” which will host IIS, OAS, and the web plugins. These machines will be node01 and node02. There will be two “app nodes” which will host all the other OBIEE components. 
 I will setup the installation with the default sample sales application. 
 Download Oracle Software
 First download 
 biee_windows_x86_101341.zip 
soa_windows_x86_101310_disk1.zip (32-bit)
 Install Oracle Software
 We will be integrating OBIEE10g with OAS 10g. Download and unzip Oracle Application Server 10.1.3.1:
 soa_windows_x86_101310_disk1.zip
 Run setup.exe
 Choose Installation Directory, and Advanced Install Next
 Then, J2EE Server and Web Server Next
 
 I simply ignored DHCP error message.

 The Install. 
 Setup Vmware Image
 Ensure that the vmware image has plenty of disk space set up. (I am using Windows 2003 SP2 32-Bit) Also ensure that 1 Gb of ram is ready for use and that you can access host system folders. Setup bridged or NAT networking. (I use bridged)
 
 Fire up the VM. 
 Log on as Administrator. Change the computer name to something identifiable – eg: OBIEE10gNode01
 
 Reboot.
