Recovery and restart need to be considered when designing and configuring sessions and workflows by using either PowerExchange Change or Real-Time. The considerations differ depending upon whether the session uses PowerExchange Client for PowerCenter (PWXPC) or PowerExchange ODBC. This is primarily due to the differences in where the restart information is maintained.

With PowerExchange ODBC, the restart information is controlled and maintained on the PowerExchange Listener platform in the internal change information file (CDEP) by using the application name specified in the connection.
