It does data manipulation language (DML) replication, but it does not do data definition language (DDL) replication. In my opinion, it is a disadvantage. It would be nicer if it was able to do both DML and DDL. I'm not 100% certain of this, but it seems Oracle Golden Gate does both DML and DDL. MIMIX only does DML, and it would be very nice if they included DDL replication. This is one feature that would be very helpful to have.
