I came across a frustrating problem today. I’d just finished processing a large tabular cube (SQL Server 2012), which had taken 11 hours in total.

On trying to connect to the cube to test it, I’d made a schoolboy error; The database was named correctly, but the model inside it was named MyCubeName_Test instead of MyCubeName. No problem, I’ll just right click the cube in SSMS and rename it. Well, no, there is no option to rename a model, just the database. I didn’t fancy doing a full reprocess, but luckily a little digging in the xml files presented a solution.

  1. Detach the cube
  2. Open up the cube’s data folder in explorer (x:\xx\OLAP\data\MyCubeName.0.db, or whatever it happens to be in your case)
  3. Find the Model.xx.cub.xml file, and open it in Notepad++ (other text editors are available…)
  4. Search for the <Name> tag, and just change the name inside it
  5. Save the file and close it
  6. Re-attach the cube
