ApsaraDB for Redis allows you to modify specific instance parameters. The instance
parameters that can be modified vary based on engine versions and architectures. This
topic describes how to modify instance parameters.
Precautions
Some parameters are not supported in earlier instance minor versions. If your instance
is in an earlier minor version, the following error message may appear when you set
the parameters. You must update your instance to the latest minor version. For more
information, see Update the minor version.

Procedure
Log on to the ApsaraDB for Redis console and go to the Instances page. In the top navigation bar, select the region in which the instance is deployed.
Then, find the instance and click the instance ID.
On the Instance Information page, click System Parameters in the left-side navigation pane.
On the System Parameters page, find the parameter that you want to modify and click
Modify in the Actions column.
In the dialog box that appears, modify the parameter value and click OK. For more
information about the parameters and their valid values, see Supported parameters.
Warning After you submit a modification to a specific instance parameter, the instance is
restarted. The instance may experience transient connections for a few seconds during
the restart. Modify instance parameters with caution. Before you modify an instance
parameter, check the Restart and Take Effect column of the parameter to make sure that the instance does not need a restart for
the modification to take effect.
