The DPF is not designed to provide HA ... it is designed to provide
scalability. There are many factors that would go into a determination as
to whether or not DPF is necessary ... examples are total raw data
volumes, SQL complexity, table sizes, etc.
In terms of HA, DB2 UDB has supported HACMP and like products for as long
as I can remember ... possibly back to V5. Log shipping is another option
.... it was added in V7.2.
