The Datacom table-based ECCR logs all changes to a single PowerExchange Logger. The PowerExchange Logger and PowerExchange Agent must run on the same MVS system as the Datacom table-based ECCR.

The PowerExchange Logger stores the changes in its log files. The PowerExchange Logger archives active logs when they become full. You must monitor the PowerExchange Logger to ensure that the archiving process keeps pace with the data flow.

If the PowerExchange Logger uses all available active log space, the Datacom table-based ECCR enters a wait state until the PowerExchange Logger archival process makes active log space available.
