Time Required: 10 minutes
Next we need to edit the Windows registry to change certain behaviours and to make sure we are ready for a RAC install.
Open a command prompt and type regedit to open the Windows registry editor.
Then navigate to the following key:
Enter a new value called LocalAccountTokenFilterPolicy and set it to type DWORD(32-bit). Set the value data to 1.
It is very important to set the value name correctly with no trailing spaces. This new value allows remote access to the Windows operating system from a named account that exists on this machine as well, provided the passwords are the same.
Later we will install Oracle as the oracle user, and by keeping the passwords consistent between the machines, oracle on Rodolfo will be able to access resources on Mimi. Without this option we would have to use a doman account or install Oracle as the Administrator user.
Next we going to disable IPv6 across all interfaces except the loopback interface. Some guides indicate this is an optional step, but failing to do this results in errors on the database install.
Navigate to the following key:
Enter a new value called DisabledComponents and set it to type DWORD(32-bit). Set the value data to ffffffff.
Next, navigate to the following key:
Edit or create a value called DisableDHCPMediaSense of type DWORD (32-bit) and set the value data to 1. This change stops Windows from uncoupling an IP address from a network interface card when the link to the local switch is lost.
Lastly we are going to locate the following registry keys:
In each case we are going to set the value EnableFirewall to 0. This change completely disables the Windows firewall and allows the Oracle installer to complete.
If you need a shortcut, you can create a REG file with all the changes listed, and then execute this in Windows by double-clicking it.
My complete winrac.reg file can be found here: winrac.reg. WordPress does not allow regsitry files to be uploaded, so the extension is DOC, although it is a raw ASCII text file.
Download the file and copy the contents to a file on your Windows VM called winrac.reg. Then execute the file.
When you execute the reg file, Windows will ask you to confirm the changes.
Once the changes have been made, reboot the VM for the changes to take effect.
