Infrastructure at your Service
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 Annual Container Adoption Survey to get a picture of container trend over the years and we…
The next SQL Saturday in Paris is coming soon and the agenda has been published by the @GUSS on twitter. Le prochain SQL Saturday Paris arrive bientôt et l’agenda a été publié sur Twitter par le @GUSS Cette année, un savant mélange de speakers francophones et internationaux, un plus pour les participants … Un rapide coup d’œil à l’agenda – si on se focalise sur la partie moteur SQL Server – montre également qu’une bonne…
Last month (April 24, 2018), the Service Pack 2 for SQL Server 2016 was released and distributed. This Service Pack has new DMVs, already available in SQL Server 2017 RTM. In this article, I will just write few words about 2 DMVs (sys.dm_db_log_stats & sys.dm_db_log_info) and a new column (modified_extent_page_count) in the DMV sys.dm_db_file_space_usage that I presented during our last event about SQL Server 2017. I think they are really helpful for DBA. It’s also…
The GDRP (General Data Protection Regulation), voted in 2016, will be applied in the European Union soon (May 25, 2018). We heard a lot of this new directive. The goal is to improve the protection and confidentiality of personally identifiable information for every European citizen. Quid of Switzerland? Read the article of Gregory here. A personal data is information that identifies a natural person, directly or indirectly. It can be a name, a photograph, an…
This article is an additional article to my precedent about “SQL Server 2017: What’s happens with an interruption during a Resumable Online Index Rebuild?” The goal is to see after I suspend the rebuild, if I can run a traditional rebuild without the option RESUME. I start an index rebuild with the option Resumable: ALTER INDEX [NCI_dbo_Transaction] ON [dbo].[Transaction] REBUILD WITH (RESUMABLE = ON, ONLINE = ON) GO In a new query window,…
Last week, I presented this option in our internal event, the dbi xChange. My colleague David Barbarin asked me this question, what’s append if an interruption occurs (reboot, SQL Server service stopped,…) during a Resumable Online Index Rebuild? I was not able to answer because I forgot to do this test. The new enhancement for an index rebuild provides the capability to suspend, resume or abort an online index operation (msdn reference). I always use…
SQL Server Management Studio is a well know integrated environment used to manage SQL Server infrastructure. This new version 17.4 can support SQL Server from 2008 up to 2017. It enhances existing features like Showplan, XE Profiler (complete list here) but also add an interesting one which is the Vulnerability Assessment. Vulnerability Assessment will scan a database in order to help you to track security holes and deviations. Rules to define those deviations are based…
Let’s continue with this blog post series about SQL Server and Docker. A couple of days ago, I was in a customer shop that already implemented SQL Server 2017 on Linux as Docker containers. It was definitely a very interesting day with a lot of customer experience and feedbacks. We discussed with him about lot of architecture scenarios. The interesting point here is I was able to compare with a previous customer who used docker…
This blog post draws on the previous article about index seek and gotchas. I encountered another interesting case but it is not so much because of the nature of the problem I decided to write this article but rather the different ways that exist to troubleshoot it. Firstly, let’s set the scene: A simple update query and its corresponding execution plan that tend to say the plan is efficient in terms of performance declare @P0…
SQL Server 2017 is available on multiple platforms: Windows, Linux and Docker. The latter provides containerization features with no lengthy setup and special prerequisites before running your SQL Server databases which are probably the key success of adoption for developers. It was my case as developer for our DMK management kit which provide to our customers a SQL Server database maintenance solution on all editions from SQL Server 2005 to SQL Server 2017 (including Linux)….
