To change the refresh frequency of the cube

  1. In the settingID box, type:


  2. In the newValue box, type the new number in seconds, and then click Invoke.

    If you reduce the interval to less than the default of two hours (7200 seconds), processing of the data warehouse will consume server resources more frequently. Depending on the volume of data that your deployment has to process, you may want to reduce the interval to one hour (3600 seconds) or increase it to more than two hours.

    A confirmation Web page appears and indicates that the IncrementalProcessIntervalSeconds setting has been changed.

To change other process control settings of the data warehouse

  1. On the ChangeSetting page, type an entry for the settingID and newValue, and then click Invoke.

    For a description of each setting and the default values and measures that are assigned to each setting, see .

    A browser window will open. The service indicates that the setting has been changed to the new value.
