This topic describes how to configure database parameters for an ApsaraDB for MongoDB
instance to better fit your business needs.
Prerequisites
The instance is a standalone or replica set instance.
Precautions
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.
Procedure
- Log on to the ApsaraDB for MongoDB console.
- In the upper-left corner of the page, select the resource group and the region of
the target instance.
- In the left-side navigation pane, click Replica Set Instances.
- Find the target instance and click its ID.
- In the left-side navigation pane, choose .
- Click Modify Parameter.

Note On the parameter list, you can check whether the instance needs to be restarted after
you modify a parameter.
- In the Modify Parameter dialog box that appears, modify parameters as needed.

Note
- You can modify more than one parameter in this step.
- You must configure parameters in compliance with the value ranges displayed in the
console.
- Click OK.
