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.

2010 First Quarter Goals

I have been reading several blog postings about 2010 goals. First, I want to applaud all of you for setting goals for the entire year. Moreover, I would like to say that I admire those that can actually achieve their annual goals, like my good friend Steve Jones. Can you all believe that he ran everyday last year? Congratulations Steve!!.

My goals tend to change as the year progresses. As a result, I decided to focus on setting quarterly instead of annual goals. Some may think that I lack ambition and drive. Well, I laugh in your face. Sometimes setting such long-term goals tend to be overwhelming and often my focus changes therefore my goals change. So here are my first quarter goals:

1. Learn everything I can about SQL Server Analysis Server

2. Two blog postings per week.

3. Publish two articles

4. Speak at a minimum of three events (SQLSaturday, SQLLunch, PASS Virtual Chapter, etc…)

5. Schedule SQL Lunch speakers for the rest of the year (at least 2 per month)

6. Submit 2 videos to SQL Share

7. Submit an abstract to SQL Server Standard (Grant Fritchey)

For some of you more ambitious people this may seem like a short list, but remember this is only for the first quarter of 2010. Every couple of weeks I will post a progress chart from the previous two weeks.

Talk to you soon
