V$PROPAGATION_RECEIVER

V$PROPAGATION_RECEIVER displays information about buffer queue propagation schedules on the receiving (destination) side. The values are reset to zero when the database (or instance in an Oracle Real Application Clusters (Oracle RAC) environment) restarts, when propagation migrates to another instance, or when an unscheduled propagation is attempted.
