Limit Ping Meters Count from Responder Explorer

In Responder Explorer, end users can ping meters downstream of any device (except service points) within the Incident view. Users can also select one or many customers from the Customers tab and request a ping. You can set a maximum number of meters that are allowed to be pinged while working in Responder Explorer. The purpose of a maximum is to prevent an ill-advised ping (for example, downstream of a substation circuit breaker with thousands of meters) that could affect performance and over-extend the application.

Before setting a maximum, ensure you communicate with your users to find an appropriate maximum that does not hamper their business needs while still protecting the performance of the application.

This setting is found in the Responder DatabaseSchemaConfig file, which by default is in C:\Program Files (x86)\Miner and Miner\Responder\Server.

To limit the number of meters when using the tools within Responder Explorer, follow these steps:

Navigate to the folder C:\Program Files (x86)\Miner and Miner\Responder\Server
Open the DatabaseSchemaConfig XML configuration file in a text editor such as Notepad ++.

IMPORTANT: There are two files named DatabaseSchemaConfig. Edit the XML Document, not the XML Schema File.
Locate the Domain Name “RXINT_CONFIG.”

TIP: The easiest way to locate the proper setting is to search for MAXPINGREQUESTS.
Set the DomainPair Value. In the following example, it is set to 100. This establishes the maximum number of meters that are allowed to be pinged in the same request.
```
<Domain Name="RXINT_CONFIG" xsi:type="CodedDomainConfig" DataType="Int32">
   <DomainPair Value="100" Description="MAXPINGREQUESTS" />
</Domain>
```
Restart the Responder service to enact your change for your users.

Depending on how the users initiate the ping request, they receive the following message if they exceed the max ping limit:

If a user attempts a downstream ping that exceeds the max ping, the following message appears:
If the user highlights a sum of customers in the Customers tab that exceeds the max ping value, the following message appears:

IMPORTANT: Unlike the Limit Ping Meters Count from ArcMap, there are no subset options provided to the user. In Responder Explorer, you must be below the limit to run the ping function.
