Enable configuration parameter for reloading availability

About this task

To set up required configuration parameters for reloading availability:

Decide on the location for the external product model directory. This directory must:
- Be accessible to the application server
- Be named productmodel
- Not be in the deployment directory of the application server
For example, you could name this directory:
```
c:\PC_Reload_Availability\productmodel
```
Create the external product model directory in the file system.
In Studio, use the Project window to navigate to configuration > config and open config.xml.
Find the ExternalProductModelDirectory parameter.
Enter the fully qualified path to the reload directory in the value attribute. For example, you can define ExternalProductModelDirectory as follows:
```
<param name="ExternalProductModelDirectory" value="c:\PC_Reload_Availability\productmodel"/>
```
If the server is in development mode, find the EnableInternalDebugTools parameter and set its value to true. To view the Reload Availability screen when the server is in development mode, this parameter must be true. For more information, see Reload Availability screen.
Start or restart PolicyCenter to pick up the changes to config.xml.
