June 2009 - Posts

I always like working at home with my patio door open, we had a really heavy rain shower and I got a visitor.

Anyway, this video is one of the instances of me chasing him/her out of my office.

So much for prepping for my LiveMeeting this afternoon :)

Tony.

If you want to see how far along your restore or backup is then you can do this... 

select percent_complete
from sys.dm_exec_requests
where session_id = 53

This is in addition to the STATS = n option on the BACKUP/RESTORE commands.

 

I'm migrating one of my clients from SQL Server 2000 to SQL Server 2008, they currently have an active/passive SQL Server 2000 cluster and we are going to keep the same architecture but on SQL Server 2008.

The licence "expert" first states that SQL Server 2008 Standard edition doesn't have clustering - so, that got corrected with a link onto the MS website; now I'm told you need two licences for a SQL Server 2008 active/passive cluster - wrong again and here are the bits from MS...

http://www.microsoft.com/sqlserver/2008/en/us/licensing-faq.aspx:

Q.  If I am doing log shipping in an active/passive failover configuration, how should I license the backup server?

A.  

In this scenario, the passive server does not require a license, unless the passive server has more processors than the active server, and the active server is licensed under the per processor model. 

Basically if you have 1 physical processor (cores doesn't matter) in your active and you have 2 physical processors in the passive then that is not legal; but, if you have 1 in the active and 1 in the passive then that is legal.

Another link: http://www.microsoft.com/Sqlserver/2005/en/us/special-considerations.aspx#passive

So....

3 servers (all with 1 physical processor), two in a active/passive cluster and one a standalone server that I'll log ship to for DR.

Licence requirements...

2 x Windows 2008 Enterprise x64 because you need Enterprise to do clustering on Windows 2008.

1 x Windows 2008 Standard x64 - standalone box.

1 x SQL Server 2008 Standard x64 Processor licence which covers the Active node; the two failover "passive" servers are covered in the EULA as follows:

(from http://www.microsoftvolumelicensing.com/userights/Downloader.aspx?DocumentId=2235 available via http://www.microsoftvolumelicensing.com/userights/DocumentSearch.aspx?Mode=3&DocumentTypeId=1)

For SQL Server 2008 Enterprise, Standard, Web and Workgroup:Fail-over Servers.  For any operating system environment in which you run instances of the server software, you may run up to the same number of passive fail-over instances in a separate operating system environment for temporary support.  The number of processors used in that separate operating system environment must not exceed the number of processors used in the corresponding operating system environment in which the active instances are running.  You may run the passive fail-over instances on a server other than the licensed server.

I know its a rant, but these guy are suppose to know their stuff when selling products - its not that often we get a new version!

We are broadcasting tonights UK SQL Server User Group meeting in Reading, for more information go to http://sqlserverfaq.com/events/168/SQL-2008-R2-and-Gemini-From-Data-Modelling-to-Information-Architecture-and-Attribute-Relationships-Aggregations-and-using-MDX-Studio-to-its-best.aspx.

 The agenda...

6.15pm – 7:00pm Andrew Fryer, Microsoft

SQL Server 2008 R2 and Gemini
SQL Server 2008 R2 will be the release with Gemini in it. Gemini is about trying to marry self service BI for end users with proper control of that data for the IT Professional. The beta program has only been recently announced and so it’s still early days but if you want to know what to expect then this is your first real opportunity in the UK. So join Andrew Fryer for an hour of peering into what 2010 BI looks like

7:00pm - 7:45pm Ruairi Prendiville, Sybase

From Data Modeling to Information Architecture
It used to be about doing the thing right: a tactical approach for data modelling was necessary, because all the data was contained within the same domain. Now it’s about doing the right thing. Management demands information that is strategic and which helps them make business decisions. This information is more complex, housed in multiple domains, created in different languages, and used by different areas of the organisation for opposing purposes. Adding to the complexity is the critical need for it to be timely, accurate and comprehensive. 
In this 45-minute session, Andrew de Rozairo and Alex Pratt of Sybase will impart the secrets of successfully building a foundation for a comprehensive and successful information architecture. You’ll learn how to take a new approach to modelling: combining the business view, information view and the technology view to achieve a strategic vision. 

7:45pm – 8pm BREAK: Light refreshments

More time to network and ask questions...

8pm - 8:15pm Vincent Rainardi

Nugget (demo) on SSAS

8:15pm – 9.00pm Ashwani Roy

Attribute Relationships, Aggregations and using MDX Studio to its best
Setting proper relationships for the attributes of a dimension is essential from a query performance point of view. It is one of the most important things while dimensional modelling.
Aggregations are pre calculated summaries of cube data that help enable Microsoft SQL Server 2005 Analysis Services (SSAS) to provide rapid query responses. Aggregations are like fact table data grouped and aggregated to a higher level in the Hierarchy. Building the correct aggregations can greatly enhance query performance.
MDX Studio can be used to analyze complex MDX expressions, monitor performance characteristics of MDX queries and get insight into how MDX interacts with other UDM features such as attribute relationships. MDX Studio provides unique visualization representation of MDX expression and allows the user to interact with different stages of MDX execution. It is built by Mosha Pasumansky, who is inventor of MDX and one of the Architects of Microsoft Analysis Services.
