Creating local cubes from relational sources using XMLA

Hi,

I have looked at Chris Webb′s example in creating local cubes. I′m trying to follow his instructions but I think that the syntax or the code is incorrect somehow.

Code Snippet

CREATE GLOBAL CUBE statement. FILENAME|C:\myCube.cub|DDL|

<Batch xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">

<Create xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">

<Parallel>
<Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</Parallel>

Hello Inmon,

pleae visit the blog entry again and read again:

http://cwebbbi.spaces.live.com/blog/cns!7B84B0F2C239489A!883.entry

It is not possible to create a local cube from relational data with CREATE GLOBAL CUBE Syntax.

I got the sample running.

Hi J?rg,

Then I would be happy if you told me how you solved it.

This is the example I followed by Chris:

· Open MDX Sample app - yes, this is another one of those areas where SQLMS won't do the job. Connect to the Adventure Works database

· Paste a CREATE GLOBAL CUBE statement into a query pane. Don't run it yet though...

· Start a new Profiler trace on your target database

· Run the CREATE GLOBAL CUBE statement, then stop the trace

· Inside your trace, you'll see the CREATE GLOBAL CUBE statement appear twice followed by a statement which begins with something like this: "CREATE GLOBAL CUBE statement. FILENAME|c:\MyfileName.cub|DDL|" and is followed by an XMLA batch statement

· Copy the XMLA batch statement out to MDX Sample App (if you find you can't do this, you might need to save the trace as an XML file and open it in Notepad or something) and

· Close the connection to your server cube in MDX Sample app, then reconnect to the path you want to create your new cub file at, eg "c:\cubtest.cub" (instead of supplying the name of your server in the connection dialog box).

· Run the Batch statement, and your local cube is created!

Hi Inmon,

this is the sample for relational datasources

In SSMS script the database you've just created to a new query editor window. Still in SSMS, right-click on the database again and select Process, select 'Process Full' then instead of clicking OK click the Script button and choose to script to a new query editor window. You now have the two XMLA commands you need to create and process your local cube, you just need to combine them into one. Select all of the Create statement generated when you scripted the database and paste it into the Batch statement generated from the Process dialog, immediately after the first line (containing the 'Batch' command) and before the XMLA that actually does the processing. Copy the new statement, open up MDX Sample app, connect to the path of the new local cube file, paste the statement into MDX Sample app and then run it. And voila, your local cube will be built direct from the relational data source.|||

Hi Joschko,

I have read that example too. Combine the two scripts into one is no problem but I can′t connect to the path of my local cube. When I connect to my local cube I connect to Analysis Services and writing c:\myCube.cub in the server name field. The .cub file creates but following message appear:

Code Snippet

Failed to retrieve data for this request. (Microsoft.SqlServer.SmoEnum)

The 'c:\myCube.cub' local cube file cannot be opened. (Microsoft.AnalysisServices.Xmla)

The operation completed successfully (Microsoft.AnalysisServices.Xmla)

When I then run the script I recieve the following message:

Hi,

I have now succeeded with connect the script into one. Wpuld you like to confirm this?

<Batch xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
<Create xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
<Parallel>
<Process xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
</Parallel>
</Batch>

When I connect to my local cube through new query and select AS XMLA query and the run it I receive the following message:

Code Snippet

Executing the query ...

A connection cannot be made. Ensure that the server is running.

Execution complete

Inmon,

I've just got the message you sent me via my blog, but I can't reply because you're communication settings won't allow me. Can you contact me directly please? You can find my contact details at www.crossjoin.co.uk

I Chris,

You ought to have the email right now. But you can write down the detail instructions about local cubes here at msdn if you want to. Thanks again for you help.
