By default, warm standby applications do not replicate the DML commands that support SQL statement replication. To use SQL statement replication, you can:
Create table replication definitions using replicate SQLDML and send standby clauses.
Set the WS_SQLDML_REPLICATION parameter to on. The default value is UDIS. However, WS_SQLDML_REPLICATION has a lower precedence than the table replication definition for SQL replication. If your table replication definition contains send standby clause for a table, the clause determines whether or not to replicate the DML statements, regardless of the WS_SQLDML_REPLICATION parameter setting.
