PowerExchange for Adabas CDC reads an Adabas Protection Log (PLOG) to capture change data. When Adabas switches to a new PLOG, PowerExchange for Adabas CDC records the new PLOG data set name in the PLOG catalog (PCAT).

The Adabas ECCR runs in a separate address space. It periodically checks the PCAT for new PLOGs from which to capture changes and passes any changes from those logs to the PowerExchange Logger for recording.

Each Adabas ECCR captures changes for a single Adabas database. If you have multiple Adabas databases, run an Adabas ECCR for each Adabas database.
