Remember to vote for your AlwaysOn Availability Groups

While visiting a customer and helping them set up AlwaysOn Availability Groups we came across a surprising “feature”. On my laptop I had build a demo lab consisting of one domain controller, three Windows 2008R2 Core member servers with SQL 2012 SP1 installed and a full Windows 2008 R2 installation with SQL Server management studio…

From 0 to SQL Demo lab in a few easy steps – Part 3

In part 1 showed how you could install Windows on a virtual disk and use that disk to create a new virtual machine. We improved on part 2 to show how to set the administrator password or the computer name during installation to minimize user input. In part 3 we will take another step. It’s…

Using table variables (or temp tables) to speed up… or slow down

In SQL Server you can use temporary tables to store intermediate results. This is a common used technique to speed up query processing. Recently I came across a problem where the temporary tables were causing the performance degradation. I’m not going into the different temporary tables types, there are good posts on these. I’m going…

Getting HadronCore on SQL Server 2012

One of the new features of SQL Server 2012 is AlwaysOn Availability Groups. You can think of Availability Groups as Database Mirroring on steroids. Database mirroring is only limited to one database, one secondary and if you wanted to read off it you had to create a snapshot. And in the case of a failover…

Who’s the DBA Anyway? It depends.

Every now and then I get questions from DBA’s if I can tell why application Y needs sysadmin permissions. Or why it needs to be local admin on the SQL box, or why the database has to be named XYZ, or why no other databases are allowed on the instance, or why SQL 2000 is…

Weer een geslaagde SQL PASS Avond

Dinsdag 4 oktober was het weer SQL PASS tijd. Ditmaal waren we weer te gast bij IVENT en niet zoals eerder in Amsterdam maar op voormalig vliegbasis Soesterberg. De officiersmess was ook de perfecte setting voor deze avond. Ik zag bekende maar ook nieuwe gezichten, zeker de nieuwe gezichten maken de avond al geslaagd. Fijn…

Using Kerberos and Windows Authentication with SQL Server
