As promised, here the slide deck of my session “Introduction to SQL Server on Linux for DBAs“. It was for me a great moment of sharing. Thanks to all!

SQL Server on Linux: Introduction to DBFS experimental tool

By | Database Administration & Monitoring, SQL Server | 2 Comments

A couple of months ago, Microsoft announced two additional command line tools for SQL Server that are mssql-scripter and DBFS. The latter has drawn my attention because it exposes live data from SQL Server DMVs as virtual files in a virtual directory on Linux operating system. Microsoft has probably taken another positive step in the SQL Server’s adoption on Linux. Indeed, in a Linux world, we may get Kernel’s performance and configuration data either directly…

SQL Server 2017 on Linux and some log shipping scenarios

By | Database Administration & Monitoring | No Comments

In this blog let’s talk a little bit about the log-shipping feature from the SQL Server CTP 2.0. First of all, let’s say that as a Windows version, it is possible to create our own solution based on Linux (and cron jobs for example). You may find out different pointers on the internet that deal with this topic. But getting the built-in log-shipping feature from SQL Server presents some advantages. Indeed, this is basically the…

SQL Server 2017 AlwaysOn AGs and new read-scale architectures

By | Database Administration & Monitoring | No Comments

As you probably know Microsoft announced an official name for SQL Server vNext during the last Microsoft Data Amp event on April 19 2017. It becomes officially SQL Serve 2017. In my first blog post, I wrote about SQL Server on Linux and the introduction of availability groups features. At this moment the SQL Server release version was CTP 1.3. As a reminder, with previous CTP releases, listeners were unusable because they did not persist when…

SQL Server on Linux and experimental Flexible Architecture

By | Database Administration & Monitoring | No Comments

In this blog post let’s talk a little bit about SQL Server optimal installation on the Linux file system. This is probably one of the first considerations we will have as a database administrator. Actually basic installation of SQL Server can be resumed to use yum command and let the SQL Server installer place all related files on the file system. But in a production environment, the story will be different and we will have…

Introducing AlwaysOn availability groups on Linux

By | Database Administration & Monitoring | No Comments

A couple of days ago, Microsoft has rolled out the SQL Server vNext CTP 1.3 which includes very nice features and the one that interested me in the supportability of AlwaysOn availability groups on Linux. That is definitely a good news because we may benefit from new ways of architecting high-availability. There are a lot of new cool enhancements, which we’ll try to study when writing new blog posts. In this first blog, let’s learn…

SQL Server Failover Cluster on Linux and synchronizing uids/gids across nodes

By | Database Administration & Monitoring | No Comments

In my previous blog post, I talked about SQL Server on Linux and high availability. During my test, I used a NFS server to share disk resources between my cluster nodes as described in the Microsoft documentation. A couple of days ago, I decided to add a fourth node (LINUX04) to my cluster infrastructure and I expected to do this work easily. But no chance, I faced a problem I never had before on this…
