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.

Did Not Know That - Redirecting CMD to the Clipboard

One of the items I frequently deal with as a Production DBA is drive alarms.  I have written previously about looking for space inside database files, but what if your problem is non-database files?

The goto tool in Windows for me has always been du (Disk Usage) created by Mark…

Revoke the permission(s) before dropping the server principal

As a remote DBA I often have to log in to client systems for a fixed amount of time and then remove logins and other security after the work is done.

This morning while cleaning up I ended up with a new error for me:

Msg 15173, Level 16,…

No..not that Up (although it is awesome!)

As a remote service provider a common request is to follow up after a server restart (or investigate a possible server restart).  A question that inevitably comes up is "When did the server restart?"

Why Don't I have a Preferred Replica?


The client reported that the log file on their main database was growing unusually large, and when they checked the backup target the database didn't have any LOG backups!

Oh, and the database was part of an Availability Group.

Toolbox - Do You Have Current Backups?

On our managed servers we run a job each day to check that either a FULL or DIFF has run in the last 24 hours, but all-too-frequently I find myself on a server that we don't manage, trying to determine the current situation (aka the "health check").

An important thing…

Error 33206 - SQL Server Audit Failed to Create the Audit File

One of the joys of working with SQL Server is the descriptive and meaningful error messages, right?
