At TechEd North America 2013, Microsoft introduced a lot of new versions: Windows Server 2012 R2, System Center 2012 R2, Windows 8.1, Visual Studio 2013 and, and, and… SQL Server 2014, of course!8-O You think I’m crazy or it’s a joke!;-) No, No, it’s for real. You can see the first page about SQL Server 2014 on Microsoft site here:…
There are three new geospatial features in Microsoft SQL Server 2012: CircularString, CurvePolygon, and CompoundCurve. For the fun and as an example, I will test CompoundCurve, a set of circular strings that may be combined with line strings, and store a “dbi” character set in a table.:-D What is CompoundCurve? It’s a set of circular strings, or circular strings combined…
Recently, I had the chance to install the SQL Server Plug-in for Oracle Entreprise Management Grid Control 11g to monitor a SQL Server instance based on a windows host. Our client, who monitors these Oracle databases via OEM Grid Control 11g, wanted to use the same tool to also monitor SQL Server databases. In this blog posting, I will describe…

This is my Distributed Replay configuration: Creation of the trace I will use the two Distributed Replay clients to generate…

Distributed Replay is a new fonctionality of Microsoft SQL Server 2012. It helps you assess the impact of future upgrades (SQL Server, hardware, OS) or SQL Server tunings by replaying a trace captured from a productive SQL Server environment to a new SQL Server test environment.

I have read some blog postings concerning the new perfmon counters, but I have not seen really extensive overviews yet. In this post, I would like to present not only what is new, but also what has changed (or not) and how to find it. The first step is to select all objects in SQL2008R2 and SQL2012 from the view sys.dm_os_performance_counters.…
Changing the default TCP port 1433 for SQL Server is an important step for securing your SQL Server. I have written a script in PowerShell to modify the port number that helps me perform this task. This blog posting will show you how to do it. Please note that the code in this article is for SQL Server 2012 on Windows…
Diese Frage habe ich in den letzten Jahren öfters gehört. Zumindest seitdem die DBAs Oracle Datapump verwenden anstatt des alten Export/Import Tools. Angeblich war es früher mit dem Import-Parameter-Tool „INDEXFILE“ viel einfacher. Tja, die Wahrheit ist: Mit Datapump geht es noch leichter! Dies möchte ich anhand eines ganz normalen Datapump-Export–Files verdeutlichen. In folgendem Beispiel handelt es sich um einen einfachen Schema-Export,…
During one of my last MySQL mission, I encountered a “security error” with mysqldump. The mission was about migrating a MySQL database from one box to another MySQL version and from Windows to Linux with different users. In order to do that, I used mysqldump. During the import of the data, I got the following warning: ERROR 1449 (HY000) at…

La configuration des options sous Entreprise Edition avant Oracle 11g pouvait être un véritable parcours du combattant. Donc, une attention particulière devait avoir lieu avant l’installation des binaires Oracle; à savoir quelles options devaient être installées! Depuis la version 11g, les choses ont bien changé, grâce à l’utilitaire “chopt” se trouvant sous $ORACLE_HOME/bin. Voici la syntaxe d’utilisation de “chopt”: chopt…
