The primary function of PWXPC is to integrate PowerExchange with PowerCenter so that PowerCenter can access PowerExchange-controlled data and write it to various targets. With PWXPC, CDC sessions can extract change data from both PowerExchange Logger log data sets and PowerExchange Condense condense files.

PowerCenter provides transformation and data cleansing capabilities, which you can use in your CDC sessions.

The following figure shows the data flow for processing change data that PowerExchange captured from

z/OS

data sources:

In this data flow, PowerExchange ECCR components capture change data and send it to the PowerExchange Logger. Optionally, PowerExchange Condense reads data from the PowerExchange Logger log files and writes it to condense files. When a CDC session runs on the PowerCenter Integration Service machine, PWXPC uses the PWX SCLI interface to communicate with the PowerExchange Listener on the z/OS system to retrieve change data.
