Set Up Oracle ASM on an Azure Linux Virtual Machine: Challenges I Encountered and Their Solutions

 

Setting up an Oracle ASM-based database on an Azure Linux virtual machine can come with some challenges. While Microsoft provides a comprehensive official guide (Set Up Oracle ASM on an Azure Linux Virtual Machine) covering the core steps, real-world implementations often come with unexpected challenges that aren't addressed in the documentation.

In this blog post, I won’t repeat the steps already covered in the Microsoft article. Instead, I’ll walk you through the specific issues I encountered during the setup, the errors that slowed me down, and—most importantly—the solutions that worked. Whether you're a DBA, a cloud engineer, or someone exploring Oracle on Azure, I hope these insights will help you avoid similar pitfalls and save valuable time.

Here are the key problems I faced:

1. Installing Azure CLI on Windows
2. Creating an X Server VM (asmXServer) – a Windows-based VM for running graphical tools like asmca and dbca
3. Bastion Connection Failure – caused by an outdated version of Python

In the sections that follow, I’ll explain each of these issues in detail and how I successfully resolved them.

1.       Installing Azure CLI on a Windows 

To install the Azure Command-Line Interface (CLI) on your Windows 11 machine, follow these steps:

1.1. Download the Installer

Visit the official Azure CLI installation page for Windows:

👉 Install Azure CLI on Windows

1.2. Click on the "Download the MSI Installer" link to begin the download.

1.3. Run the Installer

1. Once the download completes, run the installer and follow the on-screen instructions to complete the setup.

 

1.4. NOW you have 2 options 

1. Using the Windows Powershell 
2. Using mobaXterm to run commands in the shell (Linux bash shell)

1.4.1. Using the windows powershell

To log in to Azure user the following command in Powershell

az login

Select your Microsoft account and click Continue.

Enter your Azure account, and click Next

Enter the MFA, on your mobile phone

Click Next

I encountered this problem "No subscription found for ..."

Solution: Set the Tenant ID.
To find your Tenant ID, go to the Azure Portal → navigate to Microsoft Entra ID → under Overview, you’ll see the Tenant ID listed.

Then run the following commands in the Windows Powershell

az login --tenant <Your Tenant ID>
az account show

1.4.2. Using mobaXterm to run commands in the shell (Linux bash shell)

Find out the Tenant ID.
To find your Tenant ID, go to the Azure Portal → navigate to Microsoft Entra ID → under Overview, you’ll see the Tenant ID listed.

Here I used MobaXterm and opened the Shell

Then run the following commands in the Windows Powershell

az login --tenant <Your Tenant ID>
az account show

2. Creating an X Server VM (asmXServer) 

At first, I tried to execute the following command and I received this error “Querying the image of  ‘Windows-10:win10-22h2-pro-g2:19045.2604.230207’ failed for error (NotFound) Artifact: VMImage  was not found”

 az vm create --resource-group ASMAmirLab --name asmXServer --image
MicrosoftWindowsDesktop:Windows-10:win10-22h2-pro-g2:19045.2604.230207 --size
Standard_DS1_v2 --vnet-name asmVnet --subnet asmSubnet1 --public-ip-sku
Standard --nsg "" --data-disk-delete-option Delete
--os-disk-delete-option Delete --nic-delete-option Delete --admin-username
azureuser --admin-password Amir123

I executed this command to get available windows 10 images

$ az vm image list --offer Windows-10 --all -o table

The output showed that the specific version of Windows mentioned in the Microsoft documentation was no longer available.

I changed the URN for the image to the “Windows-10:win10-22h2-pro-g2:19045.5371.250112” and executed the command. 

 az vm create --resource-group ASMAmirLab --name asmXServer --image
MicrosoftWindowsDesktop:Windows-10:windows-10:win10-22h2-pro-g2:19045.5371.250112 --size
Standard_DS1_v2 --vnet-name asmVnet --subnet asmSubnet1 --public-ip-sku
Standard --nsg "" --data-disk-delete-option Delete
--os-disk-delete-option Delete --nic-delete-option Delete --admin-username
azureuser --admin-password Amir123

3. Bastion Connection Failure

During the “Download and Prepare Oracle Grid Infrastructure” step, I encountered the following error while trying to run the command: ERROR: an error occurred. Pip failed with status code 3221225477.

asmVMid=$(az vm show --resource-group ASMAmirLab --name asmVM --query 'id' --output tsv)

az network bastion tunnel --name asmBastion
--resource-group ASMAmirLab --target-resource-id $asmVMid
--resource-port 22 --port 57500

When I executed the command with --debug, I discovered that the root cause of the problem was an outdated version of Python.     

az extension add --name bastion --debug

Therefore, I de-installed the old Python version 

Then I installed the Python 3.13

I removed Azure CLI

I rebooted the Windows, and reinstalled the Azure CLI, Now it is working the problem was my Python version.
