The PowerExchange Logger for Linux, UNIX, and Windows captures and stores change data in PowerExchange Logger log files. The log files store only the successfully committed UOWs, in chronological order by end time. When an extraction session runs, the change data is extracted from the PowerExchange Logger log files rather than from the database logs.

Use of the PowerExchange Logger is optional on Linux, UNIX, or Windows. On i5/OS or z/OS, use PowerExchange Condense.
