Getting started with Red Hat Satellite – Installation

This is the start of a series of posts I wanted to write for a long time: Getting started with Red Hat Satellite. Just in case you don’t know what it is, this statement from the official Red Hat website summarizes it quite well: “As your Red Hat® environment continues to grow, so does the need to manage it to… 

Deploying SQL Server on MiniShift / RedHat OpenShift

Currently we begin to see customer adopting containerization for SQL Server databases (mainly driven by CI/CD and DevOps trends). A lot of them are using RedHat OpenShift as container management platform. From my side, I didn’t want to setup a complete OpenShift infrastructure on my lab to test only my SQL Server pod deployment on such infrastructure. I rather installed… 

The size of Oracle Home: from 9GB to 600MB – What about SQL Server?

Holidays is over and let’s start working with a funny write-up. I was reading interesting stuff done by my colleagues Franck Pachot and Daniel Westermann about reducing the size of Oracle / PostgreSQL binaries at the minimum in the context of a Docker images. I was curious what can be done on SQL Server side on Linux environment but just… 

Catching interface state changes with Network Manager

Sometimes it is required that you can react on state changes of your network interfaces. Maybe you want to get notified by mail or you want to execute a script that does something in case an event is trapped. As usual I will be using CentOS 7 for this little demonstration but as most distributions use systemd and NetworkManager nowadays… 

Running SQL Server containers on K8s Docker for Windows CE stable channel

The release of Docker for Windows Stable version 18.06..0-ce-win70 comes with some great new features I looked for a while including the K8s support! That’s a pretty good news because this support has existed on Edge channel since the beginning of this year but no chance to install a beta version on my laptop from my side. So, we get… 

SQL Server on Linux – I/O internal thoughts

Let’s start the story from the beginning with some funny testing I tried to perform with SQL Server on Linux a couple of months ago. At that time, I wanted to get some pictures of syscalls from SQL Server as I already did in a past on Windows side with sysinternal tools as procmon and stack traces. On Linux strace… 

Dealing with automatic restart and SQL Docker containers

A couple of weeks ago, a customer asked me how to restart containers automatically after a reboot of the underlying host. In his context, it was not an insignificant question because some containers are concerned by SQL Server databases and he wanted to stay relaxed as long as possible even after a maintenance of the Linux host by sysadmins. The… 

Remote syslog from Linux and Solaris

By Franck Pachot . Auditing operations with Oracle Database is very easy. The default configuration, where SYSDBA operations go to ‘audit_file_dest’ (the ‘adump’ directory) and other operations go to the database may be sufficient to log what is done but is definitely not a correct security audit method as both destinations can have their audit trail deleted by the DBA.… 

Dealing with ugrade scenarios for SQL Server on Docker and Swarm

This blog post comes from an interesting experience with one customer about upgrading SQL Server on a Docker environment. Let’s set quickly the context: a production environment that includes a standalone Docker engine on the top of openSUSE Linux distribution with some SQL Server 2017 Linux containers. The deal was to update those SQL Server instances from 2017 CU1 to… 

Introducing SQL Server on Kubernetes

After spending some times with Docker Swarm let’s introduce SQL Server on Kubernetes (aka K8s). Why another container orchestrator? Well, because Microsoft gives a strong focus on Kubernetes in their documentation and their events and because K8s is probably one of the most popular orchestration tools in the IT industry. By the way, I like to refer to the Portworx…

OpenSSH is now available on Windows 10

A couple of days ago, the Windows 10 april 2018 update was installed on my laptop. And what, you may say? Well, surprisingly this update provides some interesting “hidden” features and one of them concerns OpenSSH that is now available on-demand in Windows 10 (and likely available soon on Windows Server). This a obviously a good news because so far, I…
