Experience

Batch Extract for Meter Exchanges

A set of batch codes that execute a Java program. This program creates a CSV file with information needed to exchange meters. This file is then transferred to a 3rd-party to upgrade the meters. After the meters are exchanged, the client receives a file containing a list of upgraded meters. The file is processed through a batch extract that updates Oracle CC&B.
