There was a question this morning on the SQL Server Community Slack channel from SvenLowry about how to launch SQL Server on Linux in Single User Mode. Well you’ve heard everyone say, it’s just SQL Server…and that’s certainly true and this is another example of that idea. The command line parameters from the sqlservr binary are passed through into the SQLPAL managed Win32 SQL Process. So let’s check out how to do this together…

New Pluralsight Course – SQL Server on Linux Administration Fundamentals My new course “SQL Server on Linux Administration Fundamentals” in now available on Pluralsight here! If you want to learn about the course, check out the trailer here or if you want to dive right in check it out here! <div> </div> <div> This course targets DBAs that design and maintain SQL Server on Linux systems (or those evaluating the technology).

In this blog post we’re going to cover systemd, process exit codes and highlight how systemd reacts in certain exit conditions from SQL Server on Linux. My friend and SQL Server guru Argenis Fernandez – @dbargenis asked about this behavior on Twitter and I’ve been meaning to write this post, so here you go! Also, there’s a Connect item filed by Argenis on this here. Vote! systemd Basics Systemd is an initialization daemon, it’s job is to bring the system to usable state.

PASS Summit is right around the corner and I’ll be there speaking on Monitoring Linux Performance for the SQL Server Admin! There’s a fantastic amount of SQL Server on Linux content available at Summit. I encourage you to attend one of these sessions. You’ll likely find me at all of these!

In this blog post we’re going to explore how SQL Server on Linux responds to external memory pressure. On Windows based SQL Server systems we’ve become accustomed to the OS signaling to SQL Server that there’s a memory shortage. When signaled, SQL Server will kindly start shrinking it’s memory caches, including the buffer pool, to maintain overall system stability and usability. We’ll that story is a little different in SQL Server on Linux…let’s look and see how SQL Server on Linux responds to external memory pressure

I’m proud to announce that I will be delivering two sessions at IT/Dev Connections in San Francisco! This is my second year at IT/Dev Connections, real content for IT pros! Networking Internals for the SQL Server Professional Tuesday, 10/24/2017: 1:15 pm – 2:30 pm Room: Contiental 7 Abstract Once data leaves your SQL Server do you know what happens or is the world of networking a black box to you? Would you like to know how data is packaged up and transmitted to other systems and what to do when things go wrong?

My new course “LFCE: Linux Service Management – HTTP Services” in now available on Pluralsight here! If you want to learn about the course, check out the trailer here or if you want to dive right in check it out here! This course targets IT professionals that design and maintain RHEL/CentOS based enterprises. It aligns with the Linux Foundation Certified System Administrator (LFCS) and Linux Foundation Certified Engineer (LFCE) and also Redhat’s RHCSA and RHCE certifications.

Earlier this week Ned Otter (@NedOtter) brought up a question about Instant File Initialization on SQL Server on Linux, check out the thread here. I was up way too early in the morning, as I normally am, so I decided to poke around and see how it was done. SQL Server pros, here you can see you can get some deep internal information from the OS very easily. Hopefully with this blog post you’ll be able to compare how this is done on Windows and draw the connections between the two platforms and leverage this technique in other areas.

So I’ve been using dbatools for automated restore tasks and came across a SQL Server Agent job that I wrote that was reporting success but the job was actually failing. What I found was the function I used, Restore-DbaDatabase, was not able to access the path that I was trying to restore databases from. The Restore-DbaDatabase function, and all dbatools functions according to the dbatools team on Slack, will throw a Warning rather than an Error by design.

A few weeks back several SQL Server bloggers discussed their academic pasts…well here I’m going to let you in on a little secret of mine too. I failed out of college too. I was a Management Information Systems major and limped along with a 1.82 GPA before I got tossed from The University of Mississippi in 1999. Fast forward a few years, in 2002 I went back to school at Benedictine University in Lisle Illinois to study Computer Science.
