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.

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.

Task Factory is a software product created by Pragmatic Works. It provides many custom SSIS components which help developers creating SSIS packages become more efficient. And as we all know, when we are more efficient, we are more productive. In this nugget, I’m going to show you how to use the File Properties task to check to see if a file exists before attempting to load it into a SQL Server database.

Here are the key features and details from PragmaticWorks.com about this task:

Reads the properties of any file and stores property in variable. Many companies receive large data files from outside their organizations and run the risk of loading the file prematurely during transmission causing an SSIS failure. Our File Properties Task gives you the power to eliminate this problem by determining if the file is in use or transmitted before loading. The File Properties Task additionally saves drive space by identifying old files ready for archive.

  • Used to read the properties of an existing file.
  • Will read the properties like File Exists, File Size, File Name, File Content, Creation Time, Is File In Use, Hidden, ReadOnly and assign them to SSIS package level variables
  • Easy to use User Interface
