You can configure the priority levels of two or more Dynamic Data Masking Servers in the Load Control action. The value of the Priority property corresponds to the frequency that the client sends the request through the Dynamic Data Masking Server. For example, if you have the priority of DDMServer1 set to one and the priority of DDMServer2 set to 19, DDMServer1 receives 5 percent of the requests from the client and DDMServer2 receives 95 percent of the requests.
Enter zero (0) as the priority level of a server to indicate that requests must only go through the server if no other server available. For example, if you have the priority of DDMServer1 set to zero and the priority of DDMServer2 set to one, DDMServer2 receives 100 percent of the requests from the client unless DDMServer2 is unavailable.
