CDC sessions that run in continuous extraction mode can then extract the change data from the PowerExchange Logger log files instead of from the source system. This practice can reduce the amount of time for CDC processing on the IBM i or z/OS system.

To provide the highest level of security for z/OS data sources, set the first parameter in the SECURITY statement to 2 in the z/OS DBMOVER configuration file. With this setting, the PowerExchange Logger for Linux, UNIX, and Windows can log data from z/OS systems only if its user credentials pass z/OS security checking. The PowerExchange Logger must use a valid z/OS user ID and password combination that has READ access to CAPX.REG.* resource profiles in the FACILITY class, which are managed by your z/OS security product.
