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.

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.

How to schedule and automate backups of all SQL Server databases in SQL Server.

Hello all,

 With the course of time, you might need to backup all the databases within a server instance automatically and schedule to backup these database monthly wise or according to your specific time set. 

Also, what I want to say is that ,I cannot stop myself to write this another blog of mine.

writing a blog and sharing some knowledge through the blog makes us really feels happy and also somewhat we also become addicted to it. :)

This may be simply for one but for someone it will be helpful for those who don't know how to do it.
 May be there are a lot of alternative methods to perform this task and many solution's.

 But I have researched a lot regarding to backup all the SQL database as well the SSAS catalogs database backup with in a particular server instance.

 Here ,I am going to show how to obtain the SQL database backup automatically along with schedule time set.

Firstly, I have created a SSIS package where I used simply “Back up Database Task “ from toolbox and click right then clicking in edit tab, we  can set the connection as show in figure1 below:


Then we can set the Backup Type as full or other type after that you can select the databases to backup as show in figure2 below where we can set required databases to backup.


After that you can set the other different properties like

1.Backup set Expire

2.Bakup to

3.Append or overwrite if backup exist

4.for everyday backup options

5.Backup location directory currently I set to default location.

6.allow compression or not.

You can figure out by looking the figure3 below.


Now all you need to create a job agent to schedule the backup task and run SSIS package. In order to do this you can check out the link by Brian Knight as

http://www.sqlshare.com/running-and-scheduling-ssis-packages_53.aspx

 or simply go to SSMS and start Sql Server Agent and right click and create new job where you have to setup some properties as shown in figure4

Here you can schedule  the backup going into the schedule tab and then just check the job working or not by right clicking it and Start job  at step then you can check the all the backup database within the default location as : C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Backup

 Hope you get  some ideas to obtain the schedule Sql databases backup automatically ,also I am thinking to post into my another blog for “ Automate and schedule all SSAS catalogs database backup with in a server instance by using Job Agent” or similar approach which have taken most of my research time and I am happy to obtain the result successfully.

 Hope, this may be simple but I think it may work out for someone .

 Thanks,

Anil Maharjan
