Count Log-shipped databases

As part of my job in the Environment Hardening group, I needed to discover the usage of log-shipping in our environment. The script below generates a count of log-shipped databases.  It demonstrates how to use SQL Server Management Objects to find the Major version of SQL Server, the Switch statement, running a SQL query and summarizing the results using the measure-object cmdlet.

We wanted to be sure log-shipping was in use where the Recovery Point Objective and Recovery Time Objective required it.

1:  # .\CountLogShippedDBs.ps1
2:  [reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null
3:  # Count log shipped databases
4:  foreach ($svr in get-content "C:\Input\ProdInstances.txt" | where {$_ -notmatch "^#"})
5:  {
6:  $svr
7:  $s = New-Object "Microsoft.SqlServer.Management.Smo.Server" "$svr"
8:  $ver = $s.Information.Version.Major
9:  $con = "server=$svr;database=master;Integrated Security=sspi"
10:   
11:  switch($ver)
12:  {
13:  {$_ -eq '8'}
14:  {$cmd = "IF OBJECT_ID('msdb.dbo.log_shipping_databases') IS NOT NULL SELECT @@SERVERNAME, COUNT(*) FROM msdb.dbo.log_shipping_databases"}
15:  {$_ -eq '9'}
16:  {$cmd = "IF OBJECT_ID('msdb.dbo.log_shipping_primary_databases') IS NOT NULL SELECT @@SERVERNAME, COUNT(*) FROM msdb.dbo.log_shipping_primary_databases"}
17:  {$_ -eq '10'}
18:  {$cmd = "IF OBJECT_ID('msdb.dbo.log_shipping_primary_databases') IS NOT NULL SELECT @@SERVERNAME, COUNT(*) FROM msdb.dbo.log_shipping_primary_databases"}
19:  }
20:  $da = new-object System.Data.SqlClient.SqlDataAdapter ($cmd, $con)
21:  $dt = new-object System.Data.DataTable
22:  trap {"Oops! $_"; continue } $da.fill($dt) | out-null
23:  $sum += $dt
24:  }
25:   
26:  $sum | measure-object -property Column2 -sum
27:

Modifying Endpoint URLs on Availability Group Replicas

I recently had to modify the Endpoint URLs on our SQL Server Availability Group replicas.  The reason for this blog post is that I could not answer the following questions: Do I need to suspend data movement prior to making this change?  Would this change require a restart of the database instance? I spent enough time searching on my own to no avail that I tossed the question to the #sqlhelp hashtag on Twitter and Slack but didn't get an answer prior to executing the change request. After reading the relevant documentation, I think it's probably a good idea to suspend data movement for this change. The T-SQL is straightforward.  USE MASTER GO ALTER AVAILABILITY GROUP [AG1]  MODIFY REPLICA ON 'SQL2012-1' WITH (ENDPOINT_URL = 'TCP://10.10.10.1:5022'); ALTER AVAILABILITY GROUP [AG1]  MODIFY REPLICA ON 'SQL2012-2' WITH (ENDPOINT_URL = 'TCP://10.10.10.2:5022'); ALTER AVAILABILITY GROUP [AG2]  MODIFY REPLICA ON 'SQL2012-1

Set Azure App Service Platform Configuration to 64 bit.

If you need to update several Azure App Services' Configuration to change the Platform setting from 32 bit to 64 bit under Configuration | General settings, this script will save you about six clicks per service and you won't forget to press the SAVE button. Ask me I know. 🙄 Login-AzureRmAccount Set-AzureRmContext  -SubscriptionName  "Your Subscription" $ResourceGroupName  =  'RG1' ,  'RG2', 'RG3' foreach  ( $g   in   $ResourceGroupName ) {       # Set PROD slot to use 64 bit Platform Setting      Get-AzureRmWebApp  -ResourceGroupName  $g  | Select Name |  %  {  Set-AzureRmWebApp  -ResourceGroupName  $g  -Name  $_ .Name  -Use32BitWorkerProcess  $false  }       # Set staging slot to use 64 bit Platform setting      Get-AzureRmWebApp  -ResourceGroupName  $g  | Select Name |  %  {  Set-AzureRmWebAppSlot  -ResourceGroupName  $g  -Name  $_ .Name  -Slot  "staging"  -Use32BitWorkerProcess  $false  }  }

AzureRM Templates 101

I've recently started working with AzureRM templates to build new environments. This document really helped me understand the template structure when I first started looking at them. https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-authoring-templates I love examples when I'm trying to learn something new and the Quick Start templates are the mother lode.  https://github.com/Azure/azure-quickstart-templates Our goal is to incorporate our templates into an Azure Blueprint so that we can quickly build new environments when needed.  AzureRM templates can be artifacts of a blueprint. https://docs.microsoft.com/en-us/azure/governance/blueprints/overview
