To configure system journal replication processes to support bi-directional flow of objects, you need the following:
-
A data group (DG) definition is unique to its three part name (Name, System 1, System 2). This allows two DG definitions to be configured to share the same data group name with system 1 and system 2 reversed. You must specify both DG definitions to use the same Data source (DTASRC) parameter value. For example, in the following table both DG definitions use DataGroup1 as the data group name and both specify *SYS1 (System 1) as their DTASRC. This results in one DG definition that replicates from A to B, while the other replicates from B to A.

Each data group definition should specify *NO for the Allow to be switched (ALWSWT) parameter.
