Big TempDB Improvement In SQL Server 2017 CTP 2.0 Setup

SQL Server 2016 is the first version of SQL Server which allows you to configure multiple files during Setup. That’s good, but it had a very severe limitation: the data files could only be created with a size up to 1GB (1024 MB). For anyone sizing TempDB properly, clearly you’re going to have sizes that are greater than 1GB, so you still had to configure TempDB manually even in SQL Server 2016. I brought this up to Microsoft in early March because I have been working with a customer who was trying to configure TempDB to their standards using SQL Server 2016, but couldn’t via Setup due to this limitation. It was a great discussion with quite a few folks (including fellow MVPs), and being honest, I didn’t think anything would be done about it in the immediate future. I was wrong.

As of SQL Server 2017 CTP 2.0, this limitation no longer exists. Setup now allows the data files you create to be up to 256GB.

Creating a 256GB data file for TempDB

Microsoft listens, folks. This combined with the AG improvements I blogged about earlier in CTP 2.0 make it a welcome release.

SQL Server 2017 Is Official & Enhancements to AGs in CTP 2.0

Well, it’s official – SQL Server v.Next which has been in preview is going to be SQL Server 2017. This was announced at the DataAmp event. While we do not have an release date, it’ll be sooner rather than later. CTP 2.0 was just released today, so go and play with it.

There are two improvements for AGs in CTP 2.0 over 1.4 for listeners on Linux:

The listener will now be persisted post-failover (I have yet to test this … will do so soon)
Read only routing should be working in this releas

In other words, the listener should work properly now in CTP 2.0.

Also, there is a new CLUSTER_TYPE called External. I’ll blog more about this another time, but this is a follow on to the AGs that do not need an underlying WSFC or Pacemaker cluster that I blogged about here.

That’s it – not a long post, but all good stuff.

A Few Days Left – 25% or 30% off Upcoming Chicago Classes

Happy Tuesday. I just wanted to make sure everyone took advantage of the great discount SQLHA is offering on our two upcoming classes in Chicago this August:

SQL Server Availability Fundamentals on Monday, August 7 (1 day)
Always On Availability Groups Boot Camp on Tuesday, August 8 though Thursday, August 10 (3 days)

The Boot Camp features our world famous labs which everyone raves about. There is no better way to learn than with hands on experience that is custom designed for this course in addition to the instructional content.

Through this Saturday, April 15, both classes are on sale for 25% off the list price. After that, there is still a discount, but this is an Early Bird special. This means that SQL Server Fundamentals would be $521.25 (list price: $695) and the Boot Camp $1646.25 (list price: $2195).

For an even bigger discount, sign up for both classes and you will get 30% off the total price, which means that for four days of SQL Server availability training, you’ll pay $2023 – less than the list price of just the Always On Availability Groups Boot Camp.
