Explanation:
To configure high availability for dbl, you can use the failover groups feature of Azure SQL Database. Failover groups allow you to manage the replication and failover of a group of databases across different regions with the same connection strings1. You can choose all, or a subset of, user databases in a logical server to be replicated to another logical server in a different region. You can also specify the failover policy, such as manual or automatic, and the grace period for data loss.
Here are the steps to create a failover group for dbl:
* Using the Azure portal:
* Go to the Azure portal and select your Azure SQL Database server that hosts dbl.
* Select Failover groups in the left menu and click on Add group.
* Enter a name for the failover group and select a secondary region that is different from the primary region.
* Click on Create a new server and enter the details for the secondary server, such as server name, admin login, password, and subscription.
* Click on Select existing database(s) and choose dbl from the list of databases on the primary server.
* Click on Configure failover policy and select the failover mode, grace period, and read-write failover endpoint mode according to your preferences.
* Click on Create to create the failover group and start the replication of dbl to the secondary server.
* Using PowerShell commands:
* Install the Azure PowerShell module and log in with your Azure account.
* Run the following command to create a new server in the secondary region: New-AzSqlServer - ResourceGroupName <your-resource-group-name> -ServerName <your-secondary-server-name>
-Location "<secondary-region-name>" -SqlAdministratorCredentials $(New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList "<your-admin-login>",
$(ConvertTo-SecureString -String "<your-password>" -AsPlainText -Force))
* Run the following command to create a new failover group with dbl: New- AzSqlDatabaseFailoverGroup -ResourceGroupName <your-resource-group-name> -ServerName
<your-primary-server-name> -PartnerResourceGroupName <your-resource-group-name> - PartnerServerName <your-secondary-server-name> -FailoverGroupName <your-failover-group- name> -Database dbl -FailoverPolicy <manual-or-automatic> -GracePeriodWithDataLossHours
<grace-period-in-hours> -ReadWriteFailoverEndpoint "<enabled-or-disabled>"
* You can modify the parameters of the command according to your preferences, such as the failover policy, grace period, and read-write failover endpoint mode.
