Server Entries to the Interfaces Files

An interfaces file contains network definitions for each SAP Replication Server and data server in a replication system. The interfaces file is located in $SYBASE/interfaces on UNIX platforms, or %SYBASE% \ini\sql.ini on Microsoft Windows platforms.

When you install SAP Replication Server in an existing SAP Sybase installation directory, the installer adds SAP Replication Server information to the existing interfaces file. When you install SAP Replication Server in a unique installation directory, the installer creates a new interfaces file. In this instance, you will have two interfaces files—one for your existing SAP applications and one for SAP Replication Server.

To allow the SAP Adaptive Server Enterprise (SAP ASE) and SAP Replication Server to communicate, you must:

Add an entry for SAP Replication Server in the SAP interfaces file used by the SAP ASEs
Add entries for the primary and replicate SAP ASEs in the SAP Replication Server interfaces file

If you use direct load materialization, the interfaces file requires an entry for the Replication Agent location.

For each server, you need:

Server name
Host name
Port number
