Conferences

The last day of PASS is here. It’s been a hectic week.

I spend the morning attending the MVP sessions. As such, I can’t say much about them. All I can say is that there’s some really exciting stuff coming in the next couple of years.

The presentation this afternoon went well, much better than I expected. Even though a couple of demos didn’t quite work. I noticed afterwards that one of the things I was demonstrating the optimiser couldn’t do, it can in SQL 2008. Oops. I’ll fix the demos before I upload them. I should get them up within a week.

The last session’s another case of how not to do things. Backups, security, encryption, database design, naming conventions, data types, stored procs. Why bother? 🙂 The audience was more involved than I would have expected at than I would have expected late on the Friday.

All done for another year. it’s been awesome. I have a few days to play tourist before going home.

I decided to skip the keynote this morning and spend some time testing my presentation on the provided projector. Looks like it’ll be fine, we’ll see tomorrow.

The first session I attended was Bob’s level 500 session on debugging memory. He wasn’t joking that it was a level 500. It probably should have been more. It was absolutely excellent, as always.

The afternoon sessions started with another CAT presentation on performance troubleshooting, management data warehouse and extended events. Extended events were what I was most interested in. Bob briefly went over events in his usual high-speed style. the most intersting part was the system health check that’s included in 2008 and is on by default. Kinda an improvement over the default trace of 2005.

The events that caught my attention that the extende events can log are the deadlock (only in CU 1) that automatically logs the deadlock graph any time a deadlock occurs, the page split, which finally gives a way to see what pages are splitting and how often, and the checkpoint start and end events which will finally answer the question of how often checkpoints occur.

Lastly, I sat in on a session on spatical indexing. It’s interesting how the spatial indexing uses the underlying b-tree structure of SQL’s index architecture. The biggest problem seems to be that the optimiser doesn’t seem to cost spatical queries correctly in some cases, meaning hints are needed to get the queries running fast.

Wednesday is the first full day of the conference and the number of people around doubled.

The keynote was interesting. I’ve already written about that so I won’t say anymore.

The first session I decided to attend was by Mark Souza of SQLCat, the customer advisory team. He went over what they’ve seen with customers and how the various features of SQL 2008 have been used. Second session, after lunch was also by the CAT team and concerned security and auditing, covering some of the 2008 features, TDE auditing and the new key management options.

The last session I did was Paul Randal’s corruption survival. Paul’s always entertaining. He did a whole set of demos and told some rather frightening stories.

The day ended with a trip to the dojo and an MVP party. Photos to follow sometime.

The opening keynote for PASS was delivered by Ted Kummert, the vice president of the data and storage division at Microsoft. He gave us a look at some things that are in development at the moment and are expected to be released before the next major version of SQL.

The first of these is Kilimanjaro. This is not modifications or fixes to the current version of SQL, rather it’s a managed self-service tool for BI as well as managability improvementys for the higher end setups.. They expect to deliver this sometime in the first half of 2010.

One of the things included in Kilimanjaro is a massive improvement in multi-server management in  Management Studio. It adds a concept called the SQL Fabric, which contaions a number of servers with a number of applications. The servers can be managed through the fabric control server, which can also provide an overview of how all the servers within the fabric are running, whether they are overloaded or have available capacity. the fabric controller also stores historical trends for the servers that it controls.
