Kenneth Fisher describes DBCC Help:
Many years ago during an interview I was asked to “Name the top 7 DBCC commands that you use.” I think I was able to name 3. Ever since then I’ve paid particular attention to DBCC commands in preparation of the day when I hear that question again. Well not to long ago I was watching Erin Stellato’s (b/t) PluralSight course “SQL Server: Understanding and Using DBCC Commands”. Note: It’s a great course and I highly recommend it. In it she goes over quite a few DBCC commands, some documented, some not. In noted two in particular.
The first one I noted gives you a list of the size and free space in the logs of all databases on the instance. Highly useful. I’ve used it repeatedly recently. Unfortunately my memory is not always the best and I can never quite remember the exact name. Which brings us to the other command.
I completely agree that Erin’s Pluralsight course is worth watching.
