WebMar 25, 2024 · What Is Backward Error? Backward error is a measure of error associated with an approximate solution to a problem. Whereas the forward error is the distance … Webpacket loss at the network level. Packet-level FEC (see Figure 4) works by adding an additional loss recovery packet for every “N” packets that are sent. This additional loss recovery packet enables network-layer equipment to reconstitute lost packets at the far end of a WAN link, before the packets are delivered to TCP or other transport ...
WebTo use the rollforward recovery method, you must have taken a backup of the database and archived the logs (by setting the logarchmeth1 and logarchmeth2 configuration parameters to a value other than OFF).Restoring the database and specifying the WITHOUT ROLLING FORWARD parameter is equivalent to using the version recovery method.
