Installation 11g

Question

Gentlemen/women:
I have successfully installed Oracle 11G on my new HP Vista machine.
There are a couple of items which are not appropriately covered in the installation documents found on the OTN site.
The document I used was “Installing Oracle Database 11g on Windows” or
http://www.oracle.com/technology/obe/11gr1_db/install/dbinst/windbinst2.htm
The pre-installation test failed because I had a network adaptor which was set to DCHP.
The recommendation was to install the MicroSoft Network loopback adapter. There are virtually no clear instructions on how to do this in VISTA.
I could find no maintenance window or utility to bring up a dialog window which would allow me to set the adapter to TCPIP or anywhere to set up the IP address, sub-mask, and the mythological check box for Virtual machine. So I let VISTA set the addresses for me.
NOTE: I have not installed MS-Virtual (anything)
Step 1: I clicked the radio button for ”Basic installation” and set my passwords to “orcacle” as suggested.
The database installed.
Afer Installation: I can connect using PL/SQL developer.
Step 2 of the Testing your installation tells you to accept the certificate
After several hours of trial and error, and reconfiguration of the loopback adapter settings, network adderess (now set to 169.254.66.152) I could finally get the browser to pass me to the certificate page.
I can now open the Internet browser and use the address of “https//localhost:1158/em” get to the certificate page. However, Vista will not issue the certificate.
Vista says The security certificate presented by this site was not presented by a trusted site.
Next line: The security certificate issued by this website was issued for a different website address.
I can continue to the LogIn window but logins fail. Meantime, I get the dreaded nmefwmi.exe has stopped working.
I planned to “Un-Install and reinstall the entire database, however, Vista does not show that 11g even exists. So, I cant use VISAT for un-install.
Any thoughts or suggestions ???

Hi fora,
Here is the guide to install loopback adapter:
The Microsoft Loopback adapter is a testing tool for a virtual network environment where network access is not available. Also, you must use the Loopback adapter if there are conflicts with a network adapter or with a network adapter driver. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information. You can also install the Loopback adapter during the unattended installation process.
Manual installation
To manually install the Microsoft Loopback adapter in Windows XP, follow these steps:
1.     Click Start, and then click Control Panel.
2.     If you are in Classic view, click Switch to Category View under Control Panel in the left pane.
3.     Double-click Printers and Other Hardware, and then click Next.
4.     Under See Also in the left pane, click Add Hardware,and then click Next.
5.     Click Yes, I have already connected the hardware, and then click Next.
6.     At the bottom of the list, click Add a new hardware device, and then click Next.
7.     Click Install the hardware that I manually select from a list, and then click Next.
8.     Click Network adapters, and then click Next.
9.     In the Manufacturer box, click Microsoft.
10.     In the Network Adapter box, click Microsoft Loopback Adapter, and then click Next.
11.     Click Finish.
After the adapter is installed successfully, you can manually configure its options, as with any other adapter. If the TCP/IP properties are configured to use DHCP, the adapter will eventually use an auto net address (169.254.x.x/16) because the adapter is not actually connected to any physical media.
Note By default, TCP/IP properties are configured to use DHCP.
The best solution so far for me was to Ignore the error message and then go in by hand and alter the listener.ora and tnsnames.ora to point to the machine by name or a static IP address such as 127.0.0.1.Otherwise Loopback adapter will mess up your router configs:
Hope this helps for future issues.
