With Replication Server 15.6 and Adaptive Server 15.0.3 ESD #1, you can replicate image and Java datatype columns in Adaptive Server tables using bulk copy-in. Replicate these datatypes to replicate databases and warm standby databases by specifying the datatypes in replication definitions, function replication definitions, and subscriptions.
See "DSI bulk copy-in," in Chapter 4, "Performance Tuning" in the Replication Server Administration Guide Volume 2 to configure bulk copy-in.
