Replication from Replication Server-to-DB2 replicate databases can use a variety of gateways.
You can use Sybase DirectConnect™ for DB2 for gateway connectivity to allow Replication Server to issue selects, inserts, updates, or deletes against the tables stored in DB2.
You can set up Replication Server-to-DB2 connectivity without a DirectConnect for DB2 gateway. For details on how to accomplish this, see the Replication Server Heterogeneous Replication Guide.
