Should SQL Servers be rebooted weekly

Published On: 2019-02-11By:

There are people out there that reboot SQL Servers (or all servers) weekly. Usually the argument that I hear for doing this is that SQL Server has memory leaks which can only be resolved by rebooting Windows.

My argument against this, is that no SQL Server doesn’t have memory leaks which cause it to need to be rebooted weekly.  SQL Server is designd to use all the RAM that’s allocated to it. By default SQL Server is configured to use 2147483647 MB of RAM, or all of the RAM in the server. You can and should be changing this setting to a lower number so that there is memory for Windows and anything else that’s installed on the box (anti-virus, SSIS packages, SSAS, etc.).  The people that I typically see doing these server reboots, have been doing them for 15-20 years, typically because back then rebooting a server would fix a problem.  It won’t anymore.

There are servers that are running SQL Server that have been up for months, or years without issue (I’m ignoring the fact that you aren’t patching SQL Server and Windows here). I’ve persoally seen boxes with pretty heavy workloads on them that have run for years without having to be rebooted.

SQL Server doesn’t have any memory leaks. It’s a world class product of Microsoft, that runs millions of databases (if not more) and makes Microsoft billions of dollars in revenue each year. Whatever memory leak you think there is in SQL Server, there’s probably isn’t. If you think there is, then contact CSS at Microsoft to report the issue as Microsoft needs to patch the problem.

The biggest problem that people will see if that the buffer pool is flushed when the SQL Server restarts, and this causes SQL Server to read all the data it needs from disk as there’s no data in RAM. This causes performance issues right after the restart of SQL Server.

If you’re restarting SQL Server because there’s some performance issues that “goes away” after a SQL Server restart, we’re going to be better off dealing with the root cause of what’s causing the problem to come up to begin with. It’s probably going to be indexing or statistics, but that’s just a guess as every server is different, but it’s probably a safe guess.  Looking at the server will tell us what the problem is for sure, so we can solve the problem (and hopefully make the server faster in the process).

Connecting to Office365 with PowerShell

Published On: 2019-01-28By:

When looking at support documents for Office365, you’ll often see instructions like “connect PowerShell to Office365,” but there are no instructions on how to do that.  I was going through this, and thought, this is a problem I can fix.  It only takes a few lines of PowerShell to connect your PowerShell to an Office365 environment.  Basically what you are doing is PowerShell Remoting.  The underlying code that you’ll want to run is this:

Set-ExecutionPolicy RemoteSigned
$UserCredential = Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri -Credential $UserCredential -Authentication Basic -AllowRedirection
Import-PSSession $Session -DisableNameChecking

When you run this code, it’ll prompt you for a username and password (that’s what the second line does). These are the credentials that you use to manage the Office365 environment.  After that, you can fire off whatever commands you need to, and they’ll be send to the Office365 farm, and the response will be sent back to your PowerShell window.

It should be noted that you’ll get an error with the line that starts with “$Session” if you have MFA on your account.  You’ll either need to disable MFA or put an exception for your IP address so that you don’t get an MFA prompt.  Once you do that, you can authenticate without MFA, and the third line of the code will work as connectinos to Office 365 via PowerShell appear not to support MFA currently.
