Well yesterday was a big day in the SQL Community, Microsoft announced that they will be developing a version of SQL Server for Linux. Check out the announcement here.
Image Source – Microsoft – http://bit.ly/1U8Afd3 This leaves us with a lot of questions, in talking with one of my customers this morning he asked some pretty cool questions. Here’s how the conversation went…
Do you think it’s going to be a replacement for MySQL/MariaDB?
I’m excited to announce that I have been named a Friend of Redgate for 2016. The program targets influential people in their respective technical communities such as SQL, .NET and ALM and enables us to participate in the conversation around product and community development.
Last year was my first year in the program and the value that it provides to the community is immeasurable. I got to see first hand the dedication Redgate has to the SQL community and to making great software.
I’m proud to announce that I will be speaking at SQLSaturday Chicago on March 5th 2016! This will be my first SQLSaturday event and I’m really excited that I get to do it as a speaker. I look forward to seeing you there! My presentation is “Performance Monitoring AlwaysOn Availability Groups”
Here’s the abstract for the talk
Have you deployed Availability Groups in your data center? Are you monitoring your Availability Groups to ensure you can meet your recovery objectives?
Update for T-SQL Tuesday #84
Well, this year I was challenged with the goal of speaking publicly three times, well I blew that out of the water and have spoken 8 times (one of which was a major IT conference) this year with one more on deck for Friday at the Albuquerque SQL Server User Group. I never thought it would have gone this far, but it certainly is fun and exciting.
What I’ve noticed this year is that there’s really not another group of people like the SQL Community. Earlier this year Paul Randal ( b | t ), in the name of community, offered his services to mentor to a small group of people. Check it out here. Crazy as it may sound he went ahead and offered mentoring to everyone that submitted here and I was on that list. Here’s my blog post submission
In our final post in our “Load Testing Your Storage Subsystem with Diskspd” series, we’re going to look at output from Diskspd and run some tests and interpret results. In our first post we showed how performance can vary based on access pattern and IO size. In our second post we showed how to design a test to highlight those performance characteristics and in this post we’ll execute those tests and review the results.
In this post we’re going discuss how to implement load testing of your storage subsystem with DiskSpd. We’re going to craft tests to measure bandwidth and latency for specific access patterns and IO sizes. In the last post “Load Testing Your Storage Subsystem with Diskspd” we looked closely at access patterns and I/O size and discussed the impact each has on key performance attributes. Diskspd command options Let’s start with some common command options, don’t get caught up on the syntax.
Encrypting Connections To SQL Server Using Certificates In this post we’re going to cover configuring a connection string in .NET applications for encrypting connections to SQL Server using certificates. The audience for this document is a developer that needs to configure encrypted connections from applications to a database server.
Encrypting connections with SQL Server using Certificates consists of two parts:
An appropriately configured connection string A server certificate installed on the Database Engine (not covered in this post) Configuring a Connection String
One of the primary activities I do before bringing SQL Server into production is load testing the storage subsystem. On a new system this is critical because I want to ensure that we’re “getting what we’ve paid for” when it comes to the disk subsystem. All too often there’s a configuration issue, component mismatch, a fundamental misunderstanding of the technology or worse an insufficient disk subsystem…these all can lead to poor disk performance.
In previous posts here and here we discussed AlwaysOn Availability Group replication latency and monitoring concepts, specifically the importance of monitoring the send_queue and redo_queue. In this post I’m going to show you a technique for monitoring Availability Group replication latency with Redgate SQL Monitor and its Custom Metric functionality.
Here’s the rub, monitoring AGs is a little interesting for the following reasons
We’re interested in trending and monitoring and that isn’t built into SQL Server or SSMS’s AlwaysOn Dashboard.
