Note: This post contains a video clip where I show quirky behaviour of the scripted offline task. Personally I rarely use SQL Server Management Studio GUI to do day-to-day tasks, I rather just load a window and start typing stuff (I learn better that way). Recently I became lazy and just loaded up the tool and found something quite quirky, let me explain.
TDE (Transparent Data Encryption) encrypts the data files at rest but don’t forget that it also encrypts your backup file too. I fancied looking inside the MDF and a backup of my database before enabling TDE and comparing it to when enabled.
My database is in the recovery pending state and I want to get in and extract the data out into a new database, I have NO BACKUPS available so some data (even if it is dodgy) is better than nothing.
The title is adapted from a child-hood movie of mine and is my daily (database-related) WTF moment and it is my entry for this month’s T-SQL Tuesday found: http://www.pontop.dk/single-post/2017/03/07/Announcing-T-SQL-Tuesday-88-%E2%80%93-The-daily-database-related-WTF
I decided to accept Grant’s (TheScaryDBA) challenge found here- http://www.scarydba.com/2017/03/02/random-blog-post-challenge/ where we have to write a technical blog post that incorporates a certain image of a certain individual.
A nice little error log feature that I noticed in SQL Server 2016 regarding tempdb.
For this blog post I want to discuss the meaning behind SQL Server: Memory Manager\Target Server Memory (KB) and SQL Server: Memory Manager \Total memory (KB) Perfmon counters. I will mention how under different situations and configuration settings their behaviour changes.
SQL Server Management Studio (SSMS) release candidate 17.0 RC2 works side-by-side with generally available releases (16.x), but it is not recommended for production use. There are many enhancements which you can read here: https://docs.microsoft.com/en-us/sql/ssms/sql-server-management-studio-ssms-release-candidate but there is one feature I really like. It is called Presenter Mode and it is something I will use for my upcoming presentation. (Yes you read that right – might as well try presenting because apparently I like talking)
Since installing SQL Server vNext CTP 1.3 I found out that there is a new way to return statistics histogram for a specific stat which actually is also available with the latest Cumulative Update for SQL Server 2016 Service Pack 1.
Working with a couple of databases that needed TDE I noticed when I enabled one of them that it was stuck on “encryption in progress” for quite a while.
