Setting limits for data file uploads

You can control how data files are uploaded to IBM® Cognos® Analytics. Follow these steps to specify the encryption and size limits of data for uploaded data files.

Tips:
  • These settings apply to uploaded data files only; they do not apply to other types of data, such as data sets.
  • To change the location of the directory for uploaded data files, start Cognos Configuration, click Environment and then edit the value of the Data files location property. The default value is ../data. For more information, see the IBM Cognos Analytics Installation and Configuration Guide.

Procedure
