The PowerExchange Logger for z/OS received a Resource Interest List from a log reader address space and processed it successfully. The Resource Interest List provides a list of registration EDMNAMEs for the source objects in which the log reader is interested. The PowerExchange Logger uses this list to filter change records from the log data so that only change records of interest are sent to the log reader address space. This filtering reduces resource consumption in the log read process. The message reports the number of EDMNAMEs in the Resource Interest List.
