<p>This article describes how to modify a parameter in the Redis console.</p> <p><strong><span style="font-size:18px">Limitations</span></strong></p> <p>Some parameters take effect only after you restart the instance. For more information about these parameters, see the prompt messages in the console.</p> <p><strong><span style="font-size:18px">Prerequisites</span></strong></p> <p>You have successfully created a Redis instance. For more information, see <a href="http://pinganyun.com/ssr/help/database/Redis/User_Guide.Instance_Management.Create_Instance" target="_blank">Create an Instance</a>.</p> <p><strong><span style="font-size:18px">Usage Guidelines</span></strong></p> <p>If you modify a parameter that requires the instance restart to take effect, the system will automatically restart the instance after the modification. We recommend that you modify the parameters that require the instance restart within the maintenance period.</p> <p><strong><span style="font-size:18px">Procedures</span></strong></p> <p>1.&nbsp;&nbsp;&nbsp;&nbsp; Log in to the <a href="http://pinganyun.com/console/redis/overview" target="_blank">Redis Console</a>.</p> <p>2.&nbsp;&nbsp;&nbsp;&nbsp; In the left navigation pane, click <strong>Redis&nbsp;Cluster</strong> to enter the <strong>DBPaaS for Redis</strong> page.</p> <p>3.&nbsp;&nbsp;&nbsp;&nbsp; Select the target region.</p> <p>4.&nbsp;&nbsp;&nbsp;&nbsp; In the <strong>Operation</strong> column of the target instance, click <strong>Manage</strong>.</p> <p>5.&nbsp;&nbsp;&nbsp;&nbsp; On the page that opens, select the <strong>Parameters</strong> tab.</p> <p>6.&nbsp;&nbsp;&nbsp;&nbsp; In the <strong>Parameters</strong> area, you can view the following information:</p> <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td style="background-color:#ededed; vertical-align:top"> <p><strong>Parameter</strong></p> </td> <td style="background-color:#ededed; vertical-align:top"> <p><strong>Description</strong></p> </td> </tr> <tr> <td style="vertical-align:top"> <p>Parameter Name</p> </td> <td style="vertical-align:top"> <p>Parameter name, which cannot be modified.</p> </td> </tr> <tr> <td style="vertical-align:top"> <p>Parameter Describe</p> </td> <td style="vertical-align:top"> <p>Parameter description, which cannot be modified</p> </td> </tr> <tr> <td style="vertical-align:top"> <p>Do you have to restart to use?</p> </td> <td style="vertical-align:top"> <p>Whether the parameter modification requires the instance restart.
