If the extraction map retrieval fails, verify that the Map Location attribute specifies the correct location for the extraction maps. Extraction maps reside at the PowerExchange Listener location where the change data is captured. Only specify a value for the Map Location attribute if you have used CDC offload processing with the PowerExchange Logger for Linux, UNIX, and Windows to recapture change data from a remote system where it was originally captured to PowerExchange Logger log files on Linux, UNIX, or Windows.
