Microsoft SQL Server 2008 Service Pack 2

Microsoft finally release Microsoft SQL Server 2008 Service Pack 2 after long CTP testing…
 
Key improvements in Microsoft SQL Server 2008 Service Pack 2 are:

 

  • Reporting Services in SharePoint Integrated Mode. SQL Server 2008 SP2 provides updates for Reporting Services integration with SharePoint products.   SQL Server 2008 SP2 report servers can integrate with SharePoint 2010 products. SQL Server 2008 SP2 also provides a new add-in to support the integration of SQL Server 2008 R2 report servers with SharePoint 2007 products. This now enables SharePoint Server 2007 to be used with SQL Server 2008 R2 Report Server. For more information see the “What’s New in SharePoint Integration and SQL Server 2008 Service Pack 2 (SP2)” section in What’s New (Reporting Services).

 

  • SQL Server 2008 R2 Application and Multi-Server Management Compatibility with SQL Server 2008.  
    • SQL Server 2008 Instance Management With SP2 applied, an instance of the SQL Server 2008 Database Engine can be enrolled with a SQL Server 2008 R2 Utility Control Point as a managed instance of SQL Server. SQL Server 2008 SP2 enables organizations to extend the value of the Utility Control Point to instances of SQL Server 2008 SP2 without having to upgrade those servers to SQL Server 2008 R2. For more information, see Overview of SQL Server Utility in SQL Server 2008 R2 Books Online.
       
    • Data-tier Application (DAC) Support. Instances of the SQL Server 2008 Database Engine support all DAC operations delivered in SQL Server 2008 R2 after SP2 has been applied. You can deploy, upgrade, register, extract, and delete DACs. SP2 does not upgrade the SQL Server 2008 client tools to support DACs. You must use the SQL Server 2008 R2 client tools, such as SQL Server Management Studio, to perform DAC operations. A data-tier application is an entity that contains all of the database objects and instance objects used by an application. A DAC provides a single unit for authoring, deploying, and managing the data-tier objects. For more information, see Designing and Implementing Data-tier Applications.
You can download SQL 2008 SP2 from the following link…

Burn an ISO-image to CD or DVD

Many people asked me how to burn the cd or dvd from ISO files downloaded from MS site for software installations….

 

"Windows Server 2003 Resource Kit Tools"

 

http://www.microsoft.com/downloads/details.aspx?familyid=9d467a69-57ff-4ae7-96ee-b18c4790cffd&displaylang=en

 

Download rktools.exe and install it.

 

Steps to burn an ISO-image

To burn a CD/DVD from an image file when a drive letter is assigned to the CD/DVD burner type the following at the command line:

cdburn.exe d: c:\your_iso_file.iso for CD ; use Dvdburn.exe  For DVD.

Press ENTER.

Output similar to the following is displayed:

Number of blocks in ISO image is 2a4e2 – 100.0% done

Finished Writing Synchronizing Cache: burn successful!

 

Notes: The drive letter assigned to the burner in this example is D and the image file being written is located at c:\iso_2003.iso The default burn speed for this tool is 4x with the maximum burn speed being determined by the speed of the burner. Use the speed parameter to set the burn speed. The max parameter sets the burn speed of the CD/DVD burner to maximum.

Parallelism bugs in SQL 2008

I believe parallelism was introduced in SQL Server 7.0 but since then we encountered many issues with it.
Still there are bugs/issues with parallalism, please check the post by Aaron Bertrand
 

Six reasons you should be nervous about parallelism

Don’t get me wrong; parallel processing is great.  And with SQL Server in particular, there are many benefits to taking advantage of the power of multiple CPUs.  However, we have all had cases where what looked like parallelism was actually hurting us (you remember turning off hyperthreading on SQL Server boxes, right?), and cases where long CXPACKET waits completely defeated the purpose of speeding up the query with parallelism in the first place … often making the query take longer than it would with a MAXDOP 1 query hint, or in some cases run away completely, never to be seen again.
