Welcome to BlobEater

Featured

I am an IT Professional from the UK with interests in MS technology especially SQL Server and Azure. During 2015 I was mentored by Paul Randal  from SQLskills.

I have written articles for SQL Server Central, TechNet, gathered data for SQLskills Waits and Latches Library. I have also helped the SQL Server product team with testing SQL Server vNext adaptive query processing feature. I am also a member of Microsoft’s Azure Advisors and SQL Advisors Group.

My aim is to help you in your day to day work or to reinforce specific areas that I am interested in, so I try to keep things short and simple.

Blog Series: Azure Cloud “Fear” Busting

Featured

I have decided to do a 4-part series on Cloud “Fear Busting” scenarios. Why? Over the past few years working with the cloud (Azure) I have come across 4 main “fears” or “concerns” that stand out in my mind that people have highlighted when adopting cloud technology for their database tier. Each “fear” with form a blog post where I am hoping that after reading each post you will be “less” fearful. More specifically I will be looking at these topic areas:

  • I have security fears for SQL Database.
  • Performance Issues that I faced – Learn from my mistakes.
  • There is no going back – can I get the data back?
  • I’m a DBA – Will I lose control?

Deleting Azure SQL Database VNETs

This is quite a new feature (currently in preview) but an important one where we now have the ability to  isolate connectivity to a database to only a given subnet or set of subnets within your VNET. This is not a theory based blog post but a practical one, setting them up is easy but deleting them via the portal is a totally different experience.

The world of Automatic Tuning – SQL Server 2017

Times are changing, 10 years ago I would never have thought that self-tuning databases would be available as a packaged product. I was testing out SQL Server 2017 Automatic Tuning recently and I ended up with the following situation. Below shows an image from the query store.

Azure Portal – Bad Request

I had a strange issue recently when trying to login to the Azure Portal. Quite simply I would enter my login details and ended up with this message – Bad Request – Request Too Long, HTTP Error 400. The Size of the request headers is too long.

Azure SQL Database – Optimizing For Ad-hoc Workloads

Today I found out that it is now possible to enable the setting optimize for ad-hoc workloads at the database level when using Azure SQL Database. Traditionally this was always set at the server level for locally based SQL Servers.

Azure SQL Analytics

Azure SQL Analytics is currently in preview mode, still it is very impressive. The goal of this feature is to visualize important SQL performance metrics for your Azure SQL Database. There are a couple of things you need to do first.

  • Setup a Log Analytics workspace.
  • Enable diagnostics for your SQL Databases and/or elastic pools.

Please see the prerequisites section within this document – YOU MUST do this else you will not be able to use this feature. https://docs.microsoft.com/en-us/azure/log-analytics/log-analytics-azure-sql#prerequisites

Once setup it should take approximately 15 minutes to start capturing and rendering back some data. Don’t be surprised if it does take a little longer as was the case for myself.

A Basic Bot using Azure Bot Services

I wanted to break out my comfort levels and do something different from Azure SQL Database or straight SQL Server. I really did try something new and created a Chat Bot using Azure’s Bot Service. Warning: I am a DBA by day (and night) so this is a fun post where I am trying out different areas of Azure so I apologise if you find this too basic – its Christmas lets have some fun!

It is split across two parts. First you have to create a knowledge base which I did via the QnA Maker tool. Then secondly you use this knowledge base and link it to your Azure Bot Service.
