The PowerExchange Agent has the following resource usage characteristics:

Very low CPU usage
Very low I/O activity
Very low virtual memory usage
Not affected by change capture activity

Because the PowerExchange Agent performs work on behalf of the other PowerExchange CDC components, Informatica recommends that you assign it to a service class that has the same priority as the other CDC components or a higher priority than the other CDC components. Because the PowerExchange Agent has very low resource usage, consider running it in the service class SYSSTC.
