To support the enhanced replication definition change process, Replication Server includes changes to the rs_columns, rs_locater, and rs_objects system tables:
rs_columns – version column added.
rs_locater – C, F, and S values added to type column.
rs_objects – active_inbound, attributes2, and version columns added.
See Chapter 8, “Replication Server System Tables” in the Replication Server Reference Manual.
