The traditional CDC products use the Oracle DBMS’s LogMiner package to analyze Oracle Redo Log, and due to the complicated process, data replication speed is very slow and a high load is applied to the source DB server.
On the other hand, SILCROAD directly analyzes Oracle's Redo Log without using Oracle's LogMiner package, so it guarantees a fast replication speed and minimizes the load on the source database server.
