PowerExchange Express CDC can capture change data for only a single PDB within a CDB at a time. If you want to capture change data for another PDB in the same CDB, you must configure a separate CDC environment. Informatica recommends that each CDC environment use a unique Oracle capture user ID, pwxorad.cfg file, PowerExchange Logger for Linux, UNIX, and Windows instance and pwxccl.cfg file, and capture registrations.

If you move or clone the PDB for which PowerExchange Express CDC is capturing change data to another CDB, the PowerExchange Logger for Linux, UNIX, and Windows connection to the Oracle database is lost. You must cold start the PowerExchange Logger to prevent loss of change data.
