Runtime resilience of connections between the PowerCenter Integration Service and PowerExchange Listener is optionally available for the initial connection attempt only. You must set the
Connection Retry Period
attribute to a value greater than 0 when you define PowerExchange Client for PowerCenter (PWXPC) relational and application connections. The Integration Service then retries the connection to the PowerExchange Listener after the initial connection attempt fails. If the Integration Service cannot connect to the PowerExchange Listener within the retry period, the session fails.
