During the receive operation, DCM checks each newly-created object to see if there is an object in the destination database that has the same predecessor. This is only performed when the predefined Entire database transfer set is used to generate the package, or if the object is a history member of the transfer set used to generate the package. An object version in the destination database can have the same predecessor as a received object version if a parallel version was created in the destination database, or parallel versions are received from two or more databases.
If Local Parallel Notification is specified in a transfer set, then, for each received object, DCM makes a list of parallel versions that were created in the destination database. Each user who owns or created such a version receives an email. This notice describes the received object and its parallel versions, one of which is owned by the email recipient.
