如何在 DTU 的 azure 上自动运行此脚本

Question

 $ServiceObjective = Get-AzureSqlDatabaseServiceObjective -ServerName exampledb-ServiceObjectiveName S0
 Set-AzureSqlDatabase -DatabaseName exampledb-ServerName exampledb-ServiceObjective $ServiceObjective

I can run above script to make my sql database S0 DTU level,

Can i make this automatically.

BTW i searched on forums and stackoverflow, they recommend automation account and runebook. But i dont have RunAsAccount. I dont have admin privileges and i cant create RunAsAccount. So i couldnt use runbook.

can you recommend me another way?

Thanks:)

But i dont have RunAsAccount. I dont have admin privileges and i cant create RunAsAccount. So i couldnt use runbook.

If you want to create an Automation account with run as account, you need to have Owner role in your subscription, because when creating the run as account(service principal), it will automatically add the service principal in your subscription as a Contributor , it just can be done with Owner .

But if you just want to use the runbook in automation account, you don't need the Owner role. You just need to ask the Owner in your subscription to create an automation account with run as account for you, then you will be able to create a powershell runbook and run your command above with eg Contributor role.

After the Owner creating the automation account for you, follow the steps below.

1.Navigate to the automation account -> Runbooks -> Create a runbook -> create a Powershell runbook.

2.The two commands Get-AzureSqlDatabaseServiceObjective , Set-AzureSqlDatabase , you are using belong to Azure ie ASM powershell module, it is old, and if you want to use them, you need to use Azure Classic Run As Account(which is not supported in CSP subscription). So I recommend you to use the new Az powershell module. In your automation account -> Modules , check if there are Az.Accounts and Az.Sql module, if not, in the Modules -> Browse Gallery , search for the modules and import them.)

After importing successfully, use the script as below to login and set the sql db with Standard S0.

$connectionName = "AzureRunAsConnection"
try
{
    # Get the connection "AzureRunAsConnection "
    $servicePrincipalConnection=Get-AutomationConnection -Name $connectionName         

    "Logging in to Azure..."
    Connect-AzAccount `
        -ServicePrincipal `
        -TenantId $servicePrincipalConnection.TenantId `
        -ApplicationId $servicePrincipalConnection.ApplicationId `
        -CertificateThumbprint $servicePrincipalConnection.CertificateThumbprint 
}
catch {
    if (!$servicePrincipalConnection)
    {
        $ErrorMessage = "Connection $connectionName not found."
        throw $ErrorMessage
    } else{
        Write-Error -Message $_.Exception
        throw $_.Exception
    }
}

Set-AzSqlDatabase -ResourceGroupName "<resource-group-name>" -DatabaseName "<database-name>" -ServerName "<server-name>" -Edition "Standard" -RequestedServiceObjectiveName "S0"

3.If you want to run the script automatically with a schedule, you can follow this link Scheduling a runbook in Azure Automation to do that.
