- There is a Mine and Apply processes running on each server. With 1-way replication there is only an Apply OR a Mine process running.
- Changes that are mined on the source server and then applied on the target server are not mined again on the target server. This prevents the feedback loop.
- The Mine and Apply processes are paired together. So in a typical 2-way replication there are the following 2-pairs:
- MINE - > APPLYMINE1 - APPLY1
- APPLY1 > MINE1
