Nebraska SQL from @DBA_ANDY

I’m a forty-something Microsoft SQL Server DBA of 15+ years, a devoted husband, and a father of three young boys. I have been a DBA at a public university, at a major bank, at a healthcare system, and I now work as a remote DBA with customers across the United States. I write and speak primarily about the tips and tricks that I discover along my SQL Server journey.

Where Is My Primary Replica Again?

We have many clients with multi-node Availability Groups - that is, AGs with more than two replicas.  One of the problems I have always had with Availability Group management via the GUI (admit it, you use the GUI sometimes all you non-PowerShell geeks) is the fact that most of the…

How Long Did That Job Run?

When you use the msdb tables to try to gather information on your SQL Server Agent jobs, inevitably you will end up in a situation like this:
SELECT TOP 10 
sj.name as JobName
,sjh.run_date as RunDate
,sjh.run_time as RunTime
,sjh.run_duration as Duration
from msdb.dbo.sysjobhistory sjh
join msdb.dbo.sysjobs sj
on sjh.job_id…

Pulling Security Info

A frequent request I receive is to pull a list of logins/users with certain accesses, role memberships, etc.

I had a query to use xp_logininfo to pull group membership chains - that is, DOMAIN\Andy has access, but not directly - DOMAIN\Andy has access because he is a member of DOMAIN\DBAGroup.…

Update Your Scripts!

I had an incident today where a colleague was running a Wait Stats Report and the output looked like this:

As soon as he showed me the report I knew he had an outdated script.

Each new version of SQL Server introduces new wait types, often (but not always) related…

Another Source of Knowledge

It started with a tweet from one the many members of the #sqlfamily who always has something meaningful to say, Jes Borland (blog/@grrl_geek):

How is SQL Server using more than the Max Server Memory?

As usual, the pager went off...

"Server is near 100% memory utilization - what is running?"
http://www.starshipearththebigpicture.com/wp-content/uploads/2015/09/red-alert-picard-300x228.jpg
I saw when I signed on that the Windows server was at 98% memory utilization (the sum of all processes in Windows, including but not limited to SQL Server) and that the sqlservr.exe…

Configuring a Perfmon Collector for SQL Server

Something I always stress to people when I write and present is the importance of tracking data *before* you need it.  Microsoft does a fair job collecting some data via DMVs, the default trace, and Extended Events, but the data is still very limited in many ways,…

How Bad Are Your Indexes?

In my last post "Copying SSIS packages With DTUTIL" I described a "gotcha" where the dynamic management views (DMVs) had different columns in SQL Server 2005 compared to 2008+, and I showed a version check I had built into the script to handle it.

It made me think…

Copying SSIS packages With DTUTIL

A frequent need when performing a server migration is to copy the SSIS packages from one server to a new server.  There are a couple of different ways to do this, including a wizard in SSMS. (See https://www.mssqltips.com/sqlservertip/2061/how-to-manage-ssis-packages-stored-in-multiple-sql-server-database-instances/).  The catch to this is that these are manual and they…

Why is my SQL Server using all of the RAM on the server?

The TL;DR on this is simple:

"BECAUSE IT'S SUPPOSED TO!"

A frequent complaint we receive comes from a client that has an in-house sysadmin monitoring tool like Microsoft SCOM/SCCM.  They turn the tool on and it starts red-alerting because the Windows server hosting SQL Server is at…

What Permissions Does This Login Have?

I recently was tasked with this ticket:
Please add new login Domain\Bob to server MyServer.  Grant the login the same permissions as Domain\Mary.
On the face of it, this seems relatively straightforward, right?  It is the kind of request that we all get from time to time, whether as an…

What Do You Mean There is No Current Database Backup?!?

Yet another late night/early morning tale...

The LOG backups for multiple databases on a server failed overnight (not all databases, but many of them), and looking in the output file from the LiteSpeed Maintenance plan (the client's tool of choice) I found entries like this:
