Checking for SQL Server AlwaysOn patches for Windows Server 2008R2...

Time moves slower in a big company's data centers.

Meaning, you might not get to run SQL Server AlwaysOn Availability groups on Windows Server 2012. If not, you'll have to check several patches are applied for it to work correctly on Windows Server 2008 R2.

This excellent resource provides a list of the needed patches in the FREE AlwaysOn Setup Checklist PDF.

I think the easiest way to determine if all the required patches are installed is by using the PowerShell cmdlet get-hotfix with the -computername and -id parameters.

 Beware, the example below is a single line.

get-hotfix -computername YourServerNameHere -id KB2494036, KB2494162, KB2520235, KB2524478, KB2531907, KB2550886, KB2552040, KB2578103, KB2578113, KB2582281, KB2616514, KB2654347, KB2687741, KB976097, KB980915

 If any of the patches are found, a five column result set is returned. 

 If all the patches are found, you'll see fifteen rows. 

 If none of the patches are found, the command throws an error and you'll see red.
White beats red any day.
While writing this post, Windows Server 2012 was approved for PRODUCTION deployment at my big company. 

 Does that mean time moves faster when you blog? ;-D

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...
