SQLServer

Not Just the How of AD with Linux VM/SQL 2019, but the WHY

Azure Directory is available with Linux SQL Server 2019 in Preview and as I was setting it up in my Azure environment on a Linux Red Hat 7.3 VM, I was, as many are, happy that they list the commands for the Azure CLI to set up authentication with Azure Directory, but was concerned, that with so many new to Linux, that they didn’t describe in the steps WHY we were running certain commands or setting best practices around Linux database server design.

The setup expects that you already have a Linux VM and SQL 2019 already up and running. The first step they go into is role assignment for the AD login, setting the AD login up as the VM Administrator.

Oracle RAC vs. SQL Server AG

As I have seen the benefit for having a post on Oracle database vs. SQL Server architecture, let’s move onto the next frontier- High Availability…or what people think is high availability architecture in the two platforms.

To RAC or Not to RAC

There is a constant rumble among Oracle DBAs- either all-in for Oracle Real Application Cluster, (RAC) or a desire to use it for the tool it was technically intended for. Oracle RAC can be very enticing- complex and feature rich, its the standard for engineered systems, such as Oracle Exadata and even the Oracle Data Appliance, (ODA). Newer implementation features, such as Oracle RAC One-Node offered even greater flexibility in the design of Oracle environments, but we need to also discuss what it isn’t- Oracle RAC is not a Disaster Recovery solution.

Oracle vs. SQL Server Architecture

There are a lot of DBAs that are expected to manage both Oracle and MSSQL environments. This is only going to become more common as database platforms variations with the introduction of the cloud continue. A database is a database in our management’s world and we’re expected to understand it all.

Its not an easy topic, but I’m going to post on it, taking it step by step and hopefully the diagrams will help. Its also not an apple to apple comparison, so hopefully, but starting at the base and working my way into it with as similar as comparisons as I’m able to with features, it will make sense for those out there that need to understand it.

We have a number of customers that are migrating Oracle to Azure and many love Oracle and want to keep their Oracle database as is, just bringing their licenses over to the cloud. The importance of this is they may have Azure/SQL DBAs managing them, so I’m here to help.

How Not to Perform a Difficult Update in SQL Server/Azure

I learned a long time ago, that the quickest way to do something was to not do it at all.

A friend of mine asked me if I could review an update statement that was confounding their group looking for ways to optimize it.

The table has, just short of 50 columns, a considerable number of indexes and the column in question, has a datatype set to NVarChar(8), consists of some numbers, combinations of letters and numbers, etc.

The process would take 7 ½ hours to run this update, as it parses through 100K rows at a time. There is one index that includes the CN1 column in it, but no index on just the CN1 column. This is what the update statement looks like:

Speeding up Power BI Interface for sp_Blitz/First Responder Kit

So Tracy Boggiano told me about the great First Responder kit that Brent Ozar had available to use with sp_Blitz using Power BI desktop for a UI, but that it was really slow to non-responsive as data grew. As this was focused on performance data and also included my new love of Power BI, I asked to take a look at it. Tracy was kind enough to send me a copy of her database and the support files for the responder kit and I finally had time to look into it this week. We won’t discuss how I managed to find time for this with so much expected after the holidays are now over.

Where in the World is DBA Goth Girl- Sept 11-23

Tim and I just arrived back in Colorado yesterday and just arrived-  as in Grand Junction, Colorado on the western border of Utah.  Hauling a 42Ft. 5th wheel means that you make some considerations on how far you can go and how far you want to go.

It’s going to be a busy couple of weeks and this is what’s in the plans:

Microsoft Education Data Summit

I’ll be flying to Las Vegas tomorrow morning to attend and train in Las Vegas with the rest of my technical peers in the education sector of Microsoft.  I look forward to these events, as it’s a rare time that I get to see my colleagues as a remote employee and the training is top notch.

Learn Linux With Docker and Microsoft Container Image

I just finished teaching an 8 hour pre-con at SQL Saturday Indianapolis on Essential Linux for the DBA.  The focus of the class was on what the Microsoft DBA would need to know as more SQL Server environments begin to run on Linux.

The obstacles and demands of them will be a bit different than the Oracle crowd, as they may not have the Linux Admin or Unix expertise onsite for support and have to fend for themselves more than I did starting out on Linux.

Some folks asked me why I chose to use Docker with the SQL Server image to teach the class and I wanted to demonstrate why this, over VMWare or other options were my final choice.

Visual Studio- All the Warm and Fuzzy

So I haven’t opened Visual Studio in….oh….let’s just say it’s been a few years…:)

I had a project that I needed to run and was surprised when the Solution Explorer was missing from SSMS 2017.  Its only fair to say, there was also fair warning from Microsoft.

Time is Gold

So many have asked me when I’m starting at Microsoft and the official date is Monday, June 11th now.  Many also wonder what my upper limits are on how much I can handle, well folks, it looks like we’ve reached them!

Time for #GLOC, #SQLSatDallas, #DataSummit18

The next nine days, I’m traveling to three cities for four events. We’ll just call this the 9-3-4 gauntlet of speaker life. I booked this travel as four, one-way flights to get the itinerary
I needed to make the most of my schedule and will have breaks between each event to make sure I don’t kill myself my last two weeks at Delphix.
