This step must be performed in ArcMap. A group layer allows the user to use the Toggle Layer Cache tool and refresh only the group layer. This increases performance and causes the display to refresh faster. You may create Responder layers outside of the Responder_cached group. However, these layers will not be refreshed by the Toggle Layer Cache tool.

1. Create Responder_cached group layer.
   • Right-click the top layer (Layers) in the Display tab and select New Group Layer.
   • Right-click the new group layer and select Properties.
   • On the General tab, enter Responder_cached as the Layer Name. If you choose to use a different name, be sure to modify the Miner.Responder.Explorer.exe.config file (see instructions below). This layer name is not case-sensitive.
   • Click OK.
   • Refresh the group layer by clicking the Toggle Layer Cache tool.
2. Next you will create join layers and XY event layers to present the outage information in the map.

Group Layer Name

The group layer name is specified in the Miner.Responder.Explorer.exe.config file under the <appsettings> tag (the default is Responder_cached). If you choose to change the name of the group layer, the change must be reflected in the Miner.Responder.Explorer.exe.config file. Follow the steps outlined below.

1. Open Miner.Responder.Explorer.exe.config. By default, this file is installed here: C:\Program Files (x86)\Miner and Miner\Responder\Client.
2. Look for the following XML. This line occurs in the <appSettings> section.

    <add key="ResponderCachedLayersName" value="Responder_cached" />

3. Set the value equal to the group layer name (e.g., value="GroupName"). The default setting is Responder_cached.
4. Save and close Miner.Responder.Explorer.exe.config.
