The book "Scalable Internet Architectures" (by Theo Schlossnagle) has
an example of how to build a trigger-based replication system copying
data from an Oracle database to Postgres.
It basically tracks PK values for tuples changed/deleted (which is
what the old RServer and eRServer replication systems for Postgres
did), allowing a process to come in afterwards and pull data over to
the replica.
I presume that DB2 has enough functionality to let you run triggers to
capture which tuples changed, and when. Given that, it shouldn't be
super-difficult to do what you need.
