Example of increased efficiency

This is an example of using chepoch –actual to increase efficiency in synchronization operations.

You have three replicas in a VOB family, and a subset of the synchronization pattern and schedule is shown in Partial synchronization export pattern and schedule. All replicas use receipt handlers, so incoming packets are imported immediately. First, replica sanfran_hub sends a packet to replica boston_hub. Next, boston_hub sends a packet to bangalore. This packet includes operations from sanfran_hub.

At 8:00 GMT, sanfran_hub sends a packet to bangalore. This packet contains operations originating at sanfran_hub that bangalore has already received from boston_hub. In this case, use the command chepoch –actual bangalore at sanfran_hub before generating an update packet for bangalore. When you generate the packet, the operations already imported at bangalore are excluded from the packet.
