Executing DBCC for SQL Server Analysis Services 2016

In the upcoming release of SQL Server Analysis Services 2016, one of the new features you’ll see is the ability to perform a database consistency check against your SSAS cubes and Tabular models. Just like in the database engine side of things, DBCC for SSAS checks for corruption across the entire database or individual objects within the database.

The DBCC command is shaped likes the XMLA Process command so there’s not a lot of complexity to it. Below here, you can see the basic syntax for the SSAS DBCC command. Its worthing noting that the syntax of the command will look the same whether you’re running it against an SSAS multidimensional database or Tabular model.

"http://schemas.microsoft.com/analysisservices/2003/engine">
    <Object>
        
        
        
        
    Object>

To run the DBCC command, just open a new MDX query window and use the code seen above. Enter in the IDs of your Database, cube, measure and/or partition.

When you’re running the DBCC command against a Tabular model, there are a couple things I’d like to point out.

In the element for the CubeID, you’ll need to specify the ID of the Model. And in the element for the MeasureGroupID, specify the ID for the table you want to check.

If you want to check the whole database or model for consistency, simply remove the elements the lower elements. For example, if I wanted to check the whole model, I just would leave out the elements for MeasureGroupID and PartitionID.

To find the MeasureGroupID (Table ID) or PartitionID in a Tabular model, just navigate to the Properties for that object.

Find the SSAS Tabular MeasureGroup ID or Table ID

To find the Partition ID in a Tabular model, right click the table and select Partitions. Then highlight the partition you want to check and click the Settings icon.

If you run SQL Server Profiler against SSAS while executing the DBCC command, you can see the individual checking of the columns, tables, database and more.

Upgrading Packages to SSIS 2012

Many of you may now or in the future have the need to upgrade your SSIS packages to the new SQL Server 2012 SSIS.  Luckily, upgrading from SSIS 2005 or 2008 isn’t nearly as painful as you may have experienced upgrading old DTS (SQL Server 2000) packages.  If you’re considering the upgrade to 2012 here are some of the new features you have to look forward to:

  • Usability fixes in the development environment (Resolve References, Undo, Zoom, etc…)
  • New/Changed Tasks and Transforms (CDC Control Task, Execute Package Tasks, DQS Cleansing, etc..)
  • Project Deployment Model and Integration Catalog
  • New native Logging and Execution Reports

There is far more than I could list here but you can do a search for “What’s new in SSIS 2012” just as easily as I can Smile.

The upgrade process from 2005 or 2008 to SSIS 2012 is actually very straight forward.  There are a few things to note that are not upgraded automatically through the native upgrade steps.  The following are not upgraded and may need extra attention:

  • Deployment model stays as a Package Deployment unless you do another conversion tool.
  • Configurations are not upgrades.  For example, a configuration file may reference an old driver that is not longer used in 2012 so you would have to manually upgrade these.
  • Execute Package changes are not upgraded

To get started open your old SSIS solution in SQL Server Data Tools (new name for BIDS), which will automatically launch a conversion wizard.  This conversion wizard actually does two conversions.  The first conversion is more of a Visual Studio upgrade and the second specific to SSIS.  The screenshot below shows the start of the VS upgrade, click Next past the welcome screen.

The Visual Studio conversion will ask if you would like to back up the original files.  I generally go ahead and create a backup just incase, then click Next.

Prior to starting the SSIS Conversion tool you’ll get a warning to ensure the SSIS project is coming from a trusted source so you don’t risk a security threat.  Keep in mind the Visual Studio wizard stays open in the background.

Click Next past the welcome screen of the SSIS upgrade wizard.

Select the packages you wish to upgrade and ensure to provide any package passwords then click Next.  These passwords came from the ProtectionLevel setting of the original packages.

image

There are few settings you can manipulate prior the the upgrade that are pretty straight forward.  Shown below are the default settings and I will mention that even though connection string provider names are upgraded it will not upgrade them in configurations.  So if a configuration overrides a connection it will still have the old provider.  Click Next.

image

Review the actions that will be taken by the wizard then click Finish.

image

A successful conversion should look similar to the below image.  Hit Close, which will end the SSIS upgrade wizard and return you back to the final step of the Visual Studio upgrade.

image

You are returned to the Visual Studio upgrade where you simply need to hit Close to complete the upgrade.

image

Your packages will now be upgrade and should run without problem.  As mentioned before you may still want to upgrade things like the package deployment model, configurations, and execute package tasks.
