Remove a Named Historic Region

You can use the Historic Regions section to remove any unwanted Historic Regions. When you remove a Historic Region, the historic/event data that was stored during the time specified by the Historic Region is available for deletion.

The historic/event data is deleted when the ClearSCADA server checks for expired historic data. This can be:

• Every day at midnight (Coordinated Universal Time)
• When the ClearSCADA server is started
• When the Historic Data or Event Journal life is modified (see Define the Archiving Settings).

To remove a Historic Region:

1. Access the ClearSCADA Server Configuration Tool, (see Accessing the ClearSCADA Server Configuration Tool).
2. Expand the Database Configuration branch.
3. Select Historic Regions.
4. Right-click on the background of the list of historic regions.
   A context-sensitive menu is displayed.
5. Select the Delete option.
6. Close the ClearSCADA Server Configuration Tool to apply the changes (or select another branch if further server configuration is required).

Now that you have deleted a historic region, you can either proceed to configure other Historic settings (see Historic Configuration Settings) or you can continue with the server configuration.
