Move cluster group from one node to another
First off, apologies to the 3 readers I have (I don't read my blog post, I just write), since all of them are far better than I am when it comes to clustering. To cut it short: how can you move ANY resource from one node to another? Namely, the disk witness in the quorum … Continue reading Move cluster group from one node to another
Create SQL Server aliases using registry editor
Another quick one today: how do I create an alias using the registry editor? If you want to want to ask me why would you do such a thing, it means you're reading the wrong blogJ. To cut it short, here are the entries in the registry: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo] – this is for x64 machines who … Continue reading Create SQL Server aliases using registry editor
Error message: “A database snapshot cannot be created because it failed to start” when running DBCC
I recently learned to hate even more the virtualization thing – once your host fails, guess what, everything else goes downJ. Anyway, the topic for today is not related to my personal feelings, but to DBCC failing on one of my servers. Msg 1823, Level 16, State 2, Line 1A database snapshot cannot be created … Continue reading Error message: “A database snapshot cannot be created because it failed to start” when running DBCC
Error: 17300, Severity: 16, State: 1. (Params:). The error is printed in terse mode because there was error during formatting. Tracing, ETW, notifications etc are skipped.
Another quick one for today: When you encounter such an error (see the title and the print screen below), you might want to check this first: http://social.msdn.microsoft.com/Forums/en/sqldatabaseengine/thread/b0665753-6bb6-48bb-a938-febc6e942d58 For the really lazy ones: it's a clear sign of memory pressure. I hope this helps. Best regards,io
Cannot shrink the log – now what
Happy New Year anyone (and Gong Xi Fa Cai, since it's rapidly approapching). Now this one really asks for a blog post, since I saw it too many times on various forums and I just got it on one of my production servers. I just got an alert that we're running low on space on … Continue reading Cannot shrink the log – now what
Database marked as suspect?
I just ran into a situation like this, with the CPLS where I'm teaching: "Calin, you're the guy I was expecting to call!". Riiight, all of a sudden there's big love among us, right? Nope, it was a database that was marked as suspect. For no particular reason. Okay, do you have backups? From yesterday. … Continue reading Database marked as suspect?
BACKUP DATABASE TO DISK = N‘NUL’ – and misconceptions
Hopefully this will help someone out there. There is a command, BACKUP DATBASE <db_name> TO DISK = N'NUL' and apparently people either don't know that is there, or are using it for all the wrong purposes. We use this particular command to find out our "golden point", so to speak, which means that we can … Continue reading BACKUP DATABASE TO DISK = N‘NUL’ – and misconceptions
Execution of job LSRestore_ failed. See history for details
I've been itching all day to write about this, but I got caught in way too many other small issues, but now, that I'm home, I hope I get the chance to write about this little mishap that I got today. I was documenting an emergency role change for a secondary involved in log shipping … Continue reading Execution of job LSRestore_ failed. See history for details

Alright, I bought the book and started reading it. Now, this is just my very first impression with the book, so don't take it too seriously. First of all, on a 1 to 5 scale, I would give it somewhere between 3.5 and 4. In other words, above average. OK, hold on, justice is NOT … Continue reading Book review: SQL Wait Stats Joes 2 Pros: SQL Performance Tuning Techniques Using Wait Statistics, Types & Queues
