I am asked by clients/team members/friends a lot about how to set up TEMPDB to use the D:\ drive on an Azure VM for SQL Server. Below are the steps I took to configure it on my VMs.
At one of my previous DBA jobs, I encountered some performance issues in our Azure PaaS offering. Clients were experiencing 30-40 second login times and 10-15 second save times, which is considered poor. Of course, everybody’s first thoughts were, “THE DATABASE IS SLOW!!” After pulling up every single chart and metric I could, I finally proved to them it was not the database.

One of the sessions I give at PASS events is about configuring your on-premises SQL instance. I have also been working with Database-as-a-Service, DBaaS, for a while now and thought it would be helpful to do a session on configuring DBaaS for beginners. The purpose of this blog post is to list some of the things that I believe are crucial for first time deployment

As database administrators, we are always looking for ways to automate our daily processes. SQL Server Agent has always been a great tool for doing this, whether it be for scheduling regular maintenance or administrative jobs. For those of you making the leap to the PaaS offering of Azure SQL databases, you will quickly discover that SQL Server Agent is no longer a feature. For those of you who might start to panic thinking you will now be required to wake up at 2:00 AM to manually run your weekly maintenance or nightly administrative job- don’t worry! This is where Azure Automation comes to save the day! Azure Automation brings a PowerShell workflow execution service to the Azure platform that allows one to automate those maintenance and administrative tasks all within the Azure portal and take the role of the SQL Server Agent. To demonstrate how you can leverage Azure Automation, I will take a common request that I have encountered with many clients who have the need to schedule a stored procedure execution.
My previous blog post was about the SSIS Lookup task and how it really works. Now that I have shown that the Lookup task shouldn’t be used for one-to-many or many-to-many joins, let’s take a look at the Merge Join transformation task. If you follow along with this blog, you will learn a little tip that will eliminate the requirement for you to add a SORT transformation task within your data flow task.
Databases in the Cloud
Technology leaders are being inundated with a flood of new cloud architectures, strategies and products – all guaranteed by vendors and various industry pundits to solve all of our database challenges. The seemingly endless array of public cloud based DBMS offerings can quickly become bewildering. This article is intended to peel back the veil of cloud based DBMS offerings by providing readers with our experiences with cloud based database architectures.
As the modern database continues to grow, its inherent feature set expands alongside it. More solutions allow remote DBAs and internal teams alike to solve business problems tied to cutting costs and improving efficiencies. However, with these solutions comes increased complexity surrounding database administration, and it falls on the shoulders of DBAs to understand and leverage the industry’s evolving technologies.
One of the main benefits of an AlwaysOn Availability Group is being able to read off of the secondary replicas. However, Read-Only Routing is not automatically configured when you first build your AlwaysOn Availability Group. To fully utilize an AlwaysOn Availability Group and take full advantage of having read-only connections connect to your secondary database, you will have to configure Read-Only Routing.
As the strategic role of databases continues to advance within organizations, the task of finding and retaining experienced DBAs has become increasingly difficult. DBAs are seen as the “Go-To” specialist for internal IT teams due to their knowledge across a wide spectrum of information technology and processes. In an increasingly complex environment, database administrators design, support, and safeguard a company’s critical data stores, ultimately allowing organizations to make better business decisions.
Oftentimes, I am presented with queries from a client with a myriad of joins that have no table aliases. In order to improve performance, I often will have to create temporary tables from pieces of the query, and sometimes they need to be created manually as opposed to performing a SELECT INTO. Having to search through all of the tables through the GUI manually to determine the proper information on the columns can be quite a pain and a waste of time. In an effort to better utilize my time, I created a simple query that will return where the column resides as well as everything you need to know about the column and more.
