Be Cautious When Critizing About Guidance

T-SQL
I recently posted some comments about some guidance offered by Microsoft when talking about the CXPACKET wait type. Nothing I said was wrong, no. But, evidently there are a few whip smart and agile people who work for Microsoft. Specifically, Rick Byham, who works for the team tasked with taking care of the SQL Server Books Online. Why am I calling Mr. Byham smart and agile. Evidently he saw the blog post and has completely updated the description for CXPACKET at MSDN: Occurs with parallel query plans when trying to synchronize the query processor exchange iterator. If waiting is excessive and cannot be reduced by tuning the query (such as adding indexes), consider adjusting the cost threshold for parallelism or lowering the degree of parallelism. WHOOP! That's awesome work. Thanks Mr. Byham. Of…

Getting Started With SQL Server 2014 the Easy Way

Azure, PASS
You know you want to at least take a look at the new Client Technology Preview (CTP) of SQL Server 2014. I don't blame you either.

I don't blame you. I found myself on the road the day the software was released, so I was going to attempt to do all that work on a hotel wireless system. In short, I was going to have to wait, no options. Or were there? Actually, there is a much easier option. Azure Virtual Machines. And no, it's not that I can simply get a Windows Azure VM ready to go…

Praise and a Suggestion for AlwaysOn

Uncategorized
One of my favorite additions to SQL Server 2012 is the Availability Groups, referred to as AlwaysOn. These things are awesome. It's basically shared nothing clustering at a database-by-database level. You can set up a series of secondary machines that will enable you to failover a database in the event of an outage. This is a huge advantage in high availability and disaster recovery scenarios. We're talking serious business continuity. Further, you can set up one of those secondary machines to allow for reads, meaning, you get a reporting database that allows you to offload read queries from a transactional machine. Another giant win. But wait, it gets better. Now, with the capabilities that are coming with Azure Virtual Machines and Azure Virtual Networks you can go even further. It's…
