This topic describes how to configure database parameters for an ApsaraDB for MongoDB instance to better fit your business needs.


The instance is a standalone or replica set instance.


After you save the changes to some parameters, the instance is restarted. For more information, see descriptions in the Force Restart column on the Parameter List page.

Note While the instance is restarting, it is not connected. We recommend that you restart your instance during off-peak hours to minimize the impact on your business.


  1. Log on to the ApsaraDB for MongoDB console.
  2. In the upper-left corner of the page, select the resource group and the region of the target instance.
  3. In the left-side navigation pane, click Replica Set Instances.
  4. Find the target instance and click its ID.
  5. In the left-side navigation pane, choose Parameters > Parameter List.
  6. Click Modify Parameter.
    Note On the parameter list, you can check whether the instance needs to be restarted after you modify a parameter.
  7. In the Modify Parameter dialog box, modify the parameters.
    • You can modify more than one parameter in this step.
    • You must configure parameters in compliance with the value ranges displayed in the console.
  8. Click OK.
