Oracle Grid Infrastructure can be also installed on Windows server. In this blog I am explaining how this installation can be done. I am going to install an environment with to nodes. Oracle 19c is being used. We have two servers
winrac1 :
winrac2 :
with the same characteristics
I would like to note that it is just a test environment on virtual machines on VirtualBox. I did not have any dns server and I just have 1 scan address instead of 3 as recommended. Below my hosts files with the IP used

The installation user can be local user or a domain user. If he is a local user he should
-be member of Administrators group
-exist on both nodes if he is a local one
-have the same password on both nodes
In my case the Administrator user was used
The oracle grid sofware WINDOWS.X64_193000_grid_home is already downloaded and unpacked to the GRID_HOME

The shared disks are Disk1 and Disk2 are already presented to both nodes winrac1 and winrac2
We have to disable write caching on each shared disk if supported by the system. For this right click on Disk1 for example and uncheck the Enable write caching on the device on both nodes
The next steps is to create a volume on shared disks. On the first node do following steps for all shared disks. Right click on the shared disk to create a New Simple Volume.
Once done , do a rescan disks on all other nodes
We now have to create logical partition with the shared disks

Do a rescan from all other nodes
Now we are going to prepare our disks to be used with ASM. For this we use the tool asmtoolg.exe. Just launch it on the first node
|
1
|
c:\app\19.0.0.0\grid\bin>c:\app\19.0.0.0\grid\bin\asmtoolg.exe |
Repeat these steps for all disks you will use with ASM. You can list your labelled disks with following command

Before launching the installation, we have to set these registry values on both nodes
|
1
|
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config |
And to stop the firewall on both nodes with Administrator
|
1
2
|
C:\Users\Administrator>netsh advfirewall set allprofiles state offOk. |
Login with grid and open a terminal with as an Administrator and launch the install command
|
1
|
c:\app\19.0.0.0\grid>gridSetup.bat |
As it is just a test environment, I decided to ignore the errors and to continue
The verification failed because of errors I ignored
But the installation is fine
At the end of the installation I can validate the cluster

Conclusion
We just see that Oracle Clusterware can be configured in a Windows environement. In coming blogs we will show how to configure database on it. But it will the same that on Linux environment
