Replication Server uses the rs_raw_object_serialization function string to pass Java columns to the replicate database in serialized format, which allows Replication Server to update Java columns directly. rs_raw_object_serialization is contained in rs_sqlserver_function_class and rs_default_function_class.
When a replication definition references the rawobject datatype, Replication Server creates rs_get_textptr, rs_textptr_init, rs_datarow_for_writetext, and rs_writetext function strings for each rawobject column just as it does for image data.
