Interfaces File

The interfaces file contains network definitions for servers in the replication system, including SAP Replication Servers and data servers.

Generally, one interfaces file at each site contains entries for all local and remote SAP Replication Servers and data servers. The entry for each server includes its unique name and the network information that other servers and client programs need to connect with it. The interfaces file at a site requires entries for these components:

ID Server (if SAP Replication Server is not also the ID Server)
SAP Replication Server
RSSD SAP ASE or ERSSD SAP SQL Anywhere for this SAP Replication Server
ERSSD SAP Replication Agent if a route is to be created from the current site
Data servers with databases managed by this SAP Replication Server
Backup Server to back up SAP ASE databases, including RSSDs
SAP Replication Servers at other sites that manage databases containing primary data that is replicated to this site
SAP Replication Servers at other sites with subscriptions for primary data maintained at this site
Other SAP Replication Servers to which this SAP Replication Server has a route with no intermediate SAP Replication Servers

You can use the default interfaces file or you can specify an alternative interfaces file at the command line when you start SAP Replication Server. The interfaces file is usually located in the SAP Sybase release directory. Use a text editor to modify the interfaces file. See the installation and configuration guides for your platform for more information.
