Understanding backups on AlwaysOn Availability Groups – Part 1

November 30, 2015 by

Since the AlwaysOn Availabiliy Groups feature was introduced, we got new options to make the backups strategy more complete, but also more complex. Taking an advantage of secondary replicas, we can offload both, the FULL and even the Transaction Log backups from the Primary Replica to the Secondary, leaving the Primary replica dedicated to serve the production application.

AlwaysOn Availability Groups – Curiosities to make your job easier – Part 3

October 9, 2015 by

In continuation to the Availability Groups series, here you have another curiosity coming to make your job easier and help you to provide a solution to your customers 🙂

This time we will be talking about listeners. Basically, we will be talking about the limitation of one listener per Availability Group. If you never tested / tried this, this is what happens when you already have a listener in the Availability Group, and try to create another one:

AlwaysOn Availability Groups – Curiosities to make your job easier – Part 1

September 7, 2015 by

We all love Availability Groups! Since its introduction in the SQL Server 2012, some things changed. In the beginning it was seen as “just a replacement for the database mirroring”, but when we discovered that this would support readable secondary’s, the possibility of having a listener and get rid of the shared storage – even being based on a Failover Cluster – we saw that Availability Groups is a special feature.

Cloud Witness – A new feature to make our lives easier

September 4, 2015 by

In order to have a well-configured cluster we need to setup the quorum properly, but there’s more…Here is where the Cloud Witness comes to help.

In this article, I’m going to present something that would be very useful if was already been released, but no, I need to anxiously wait for the next version of Windows Server to be released, in order to start implementing this. Even though, I’m going to share with you, SQL Shack reader, why I’m so excited with that small and simple feature.

Stretch Database – The art of extend to reduce

August 7, 2015 by

Let’s continue the hybrid saga! After two articles talking about the Azure Blob Storage and what we can do using it, it’s time to check an alternative solution, that does the same of what was presented in the last article (a Hybrid Database used as archival solution for who didn’t read). This time we are not using the Azure Blob Storage, but we are still using Azure!

The feature is…Stretch Database

Azure Blob Storage – Literally a Hybrid database deployment

August 4, 2015 by

In continuation to our hybrid deployment series, we will check few more options in order to integrate on-premises and Azure, using of course SQL Server.

In the last article we talked about Azure Blob Storage and how to use this service to store a SQL Server database entirely there. Meaning that we can have our instance in our datacenter, see the server in front of you, and still have your database stored in the cloud, with your data and log files out of your disks.

July 3, 2015 by

With the evolution of the Cloud, specifically talking about Azure, SQL Server team started to take advantage of the new opened horizon. We already discussed pros and cons of send backups to Azure, now let’s check how to do this!

Following the “Hybrid Scenarios series”, we already discussed about the connectivity options, and pros and cons of store our backup files in Azure.

In this article, we will specifically talk about the two options that we currently have, involving Azure: Blob Storage and Managed Backups.

AlwaysOn Availability Groups – How to setup AG between a clustered and standalone instance (Part 3)

May 12, 2015 by

We have already configured our Availability Group, now we need to make it flexible and accessible. It’s time to check on how to create a listener in order to make a single access point for you AG!

In continuation to our previous article, we are going to pass to another phase of this setup, as we already have our database in sync and safe, or highly available, depending of the chosen mode/architecture.

AlwaysOn Availability Groups – How to setup AG between a clustered and standalone instance (Part 1)

April 24, 2015 by

In this article we are going to explore how to configure an Availability Group between a clustered instance and a standalone instance, showing, step-by-step, how to setup a possible Disaster Recovery environment.

Introduced on SQL Server 2012, the Availability Groups brought the expectation to be an improved version of the database mirroring, which will be discontinued soon. The AlwaysOn Availability Groups was improved on SQL Server 2014, giving the capability of have more replicas, better troubleshooting possibilities and improving its availability. Comparing the Availability Groups with the database mirroring, in a very high level, we gained the possibility of have a listener to dynamically redirect the connection to the current active instance and also the capability of distribute the read workload between readable replicas. However, only the primary replica is able to write.

SQL Server 2014 – Install a clustered instance – step-by-step (3/3)

March 12, 2015 by

This article is divided in three parts, if you started here, check the first and second part to find the previous steps.

Now we need to define if the instance will work in “Windows Authentication Mode” or “Mixed Mode”. I usually choose “Mixed Mode” because there’s always an application that don’t work with domain accounts. By choosing this option you need to specify the password for the famous “sa” login. Notice that you can change the authentication mode anytime! You also need to add accounts to receive the Sysadmin privilege, this is very important… Even more if you choose the “Windows Authentication Mode”.
