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.

    <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.

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.

Folks,

There are many outlet s to get information on this year’s SQL PASS board of directors candidates. Including :

SQLPASS Election Site at elections2011.sqlpass.org

You will find candidate profiles here, forums where the candidates are answering questions and fostering discussion as well as the timelines for the election and PASS contacts if you have questions.  To take things a step further and make it easier to consume my thoughts, I took questions from many of you through our webinars and interactions and boiled them down into some youtube videos with our marketing manager doing the interviewing! Please make sure that you take some time and check them out. I created and uploaded these videos myself without any corporate help (hence the reason it took so longSmile).

I find that it’s difficult to get context in written explanations and I like for people to hear what I’m passionate about directly from me – So Please go check out the videos at
