The SQL Server Always On Failover Clustered Instance: The Senior DBA’s Ultimate Field Guide course was created in an attempt to help SQL Server DBAs and server administrators responsible for SQL Server Failover Clustered Instances (FCI) become more confident in what they do. This idea dawned on me as I was talking to customers who are unnecessarily […]
You know how it feels like to stare at this for a very long time (I ended up having to wear eyeglasses because of it.) Better yet, try it. Just for 5 minutes straight without blinking. But staring at a computer monitor for a long time isn’t the real issue. It’s the confusion of trying […]
With the continuous improvement that Microsoft has invested in the WSFC technology over the years, implementing and managing it has become a lot easier. I started doing my Gone Clustering in 60 Minutes presentation back in 2010. And I’m still amazed at how much it has improved. But I still talk about the frustrating hardware compatibility […]
Imagine getting a phone call in the middle of the night. While still figuring out who it was on the other line, you get a text message from your manager. He’s telling you that the databases are offline and that the operations team have been working on it for the past hour. But they’re stumped […]
A common administrative task that you need to deal with when managing an Always On Availability Group solution is to recreate SQL Server logins on all replicas. That’s just a fact. Because at any given point in time, an automatic failover can happen and move the Availability group to a different replica. If you don’t […]
I did my very first AMA session live almost a month ago and I’ve had great results. People were interacting during the live Q&A session while some sent follow-up questions afterwards. Given the below freezing temperatures where I’m at, I’ll keep doing this indoors for now until I can stay outside for longer than 5 […]
One of the subjects I had in senior high school was technology and home economics. Since my teacher majored in architectural drafting, she taught us how to read blueprints to have an idea about how structures are built. That’s when I noticed a crack on our wall near the TV. In the Philippines, walls are mostly […]
For more than a decade-and-a-half of working with SQL Server high availability and disaster recovery, I’ve gotten hundreds of questions from clients, event attendees, and training class students. That number has increased when Microsoft introduced Always On Availability Groups. I’m guessing it’s because of the level of complexity of the technology that tech professionals are […]
I was privileged to join one of Brent Ozar’s Office Hours podcast. In case you’re not aware, Brent and his amazing team host weekly podcasts where you can ask your SQL Server-related questions. Since I was joining in, attendees were encouraged to ask SQL Server high availability and disaster recovery-related questions. Here’s the video recording […]
A few weeks ago, I was trying to figure out why my Korg X50 music workstation was not sending MIDI data to my MacBook Pro. While the Korg X50 has its own sound library and can function without the MacBook, the use of software made it easy for me to do audio recordings. But what […]
