Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Changing the SSAS mode

You can change the mode in which SSAS runs, either Tabular or Multidimensional. To change the mode, use the Amazon Web Services Management Console or the Amazon CLI to modify the options settings in the SSAS option.

Important

You can only use one SSAS mode at a time. Make sure to delete all of the SSAS databases before changing the mode, or you receive an error.

The following Amazon RDS console procedure changes the SSAS mode to Tabular and sets the MAX_MEMORY parameter to 70 percent.
