In
a heterogeneous replication system, when information is replicated
from one data server to another, values stored at the primary data
server must often be altered so that they can be copied successfully
to a different datatype at the replicate data server.
User-created
function strings can produce these datatype translations, but require
significant user input and are limited by the capabilities of the
replicate data server.
To
make datatype translations more readily available for different
data servers, Replication Server provides heterogeneous datatype
support (HDS), an easy-to-apply methodology for translating datatypes
at the Replication Server. HDS supports selected datatype translations
between these data servers:
When you use HDS, you can choose which columns and datatypes
in the primary database are to be translated, and which replicate
data servers will receive the translations.

Server Heterogeneous Replication Guide.
See the Replication Server Configuration
Guide for your platform for instructions for installing
and setting up the objects that enables HDS.
See the Replication Server Reference Manual for
descriptions of the function strings.
