Configure active geo-replication for a pooled database in Azure SQL Database using the Azure CLI

Applies to: Azure SQL Database

This Azure CLI script example configures active geo-replication for a pooled database in Azure SQL Database and fails it over to the secondary replica of the database.

If you don't have an Azure trail subscription, create a trial subscription before you begin.

Prerequisites

If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.

• If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.

• When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.

• Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

Sample script

Sign in to Azure

Use the following script to sign in using a different subscription, replacing <Subscription ID> with your Azure Subscription ID. If you don't have an Azure trail subscription, create a trial subscription before you begin.

subscription="<subscriptionId>" # add subscription here

az account set -s $subscription # ...or use 'az login'

For more information, see set active subscription or log in interactively.

Run the script

# Configure active geo-replication for a pooled database in Azure SQL Database

# Variable block
let "randomIdentifier=$RANDOM*$RANDOM"
location="China East 2"
resourceGroup="msdocs-azuresql-rg-$randomIdentifier"
tag="setup-geodr-and-failover-elastic-pool"
server="msdocs-azuresql-server-$randomIdentifier"
database="msdocsazuresqldb$randomIdentifier"
login="azureuser"

pool="pool-$randomIdentifier"
failoverLocation="China North 2"

secondaryPool="msdocs-azuresql-secondary-pool-$randomIdentifier"

echo "Using resource group $resourceGroup with login: $login, password: $password..."

echo "Creating $resourceGroup in $location and $failoverResourceGroup in $failoverLocation..."
az group create --name $resourceGroup --location "$location" --tags $tag
az group create --name $failoverResourceGroup --location "$failoverLocation"

echo "Creating $server in $location and $secondaryServer in $failoverLocation..."
az sql server create --name $server --resource-group $resourceGroup --location "$location" --admin-user $login --admin-password $password
az sql server create --name $secondaryServer --resource-group $failoverResourceGroup --location "$failoverLocation" --admin-user $login --admin-password $password

echo "Creating $pool on $server and $secondaryPool on $secondaryServer..."
az sql elastic-pool create --name $pool --resource-group $resourceGroup --server $server --capacity 50 --db-dtu-max 50 --db-dtu-min 10 --edition "Standard"
az sql elastic-pool create --name $secondaryPool --resource-group $failoverResourceGroup --server $secondaryServer --capacity 50 --db-dtu-max 50 --db-dtu-min 10 --edition "Standard"

echo "Creating $database in $pool..."
az sql db create --name $database --resource-group $resourceGroup --server $server --elastic-pool $pool

echo "Establishing geo-replication for $database between $server and $secondaryServer..."
az sql db replica create --name $database --partner-server $secondaryServer --resource-group $resourceGroup --server $server --elastic-pool $secondaryPool --partner-resource-group $failoverResourceGroup

echo "Initiating failover to $secondaryServer..."
az sql db replica set-primary --name $database --resource-group $failoverResourceGroup --server $secondaryServer

echo "Monitoring health of $database on $secondaryServer..."
az sql db replica list-links --name $database --resource-group $failoverResourceGroup --server $secondaryServer

Clean up resources

Use the following command to remove the resource group and all resources associated with it using the az group delete command - unless you have an ongoing need for these resources. Some of these resources may take a while to create, as well as to delete.

az group delete --name $resourceGroup
az group delete --name $secondaryResourceGroup

Sample reference

This script uses the following commands. Each command in the table links to command specific documentation.
