For the interaction between a Replication Agent and a Replication Server, the only interfaces file entry that may be required is one identifying the Replication Server.
The Replication Agent for DB2 UDB requires an interfaces file entry for the Replication Server.
The Replication Agent (for DB2 Universal Database on UNIX and Windows platforms, Microsoft SQL Server, and Oracle) does not require an interfaces file entry, as it records the Replication Server host name and port number in configuration parameters.
The values of the server and database names are not significant in a Replication Server connection definition for a Replication Agent User thread. However, they must be properly configured in the Replication Agent.
The Replication Agent rs_source_ds and rs_source_db configuration parameters must be configured to match the ds.db values of the Replication Server connection name. If they do not match, the Replication Agent will not find a Replication Server connection to send information to.
Since Replication Server never attempts to contact the Replication Agent User thread of a connection, if the connection is only for a Replication Agent User thread, there is no need for the server name portion of the connection to exist in an interfaces file. The database name portion of the Replication Server connection is also arbitrary, if the connection is only for a Replication Agent User thread.
Any unique combination of two strings (namex.namey) can be used to identify a Replication Agent User thread connection. For convenience, you should choose names that have some meaning in your particular environment (for example, host.db2_subsystem, host.oracle_sid, and so on).
