Illustrations in this book use icons to represent the components of a replication system.
This icon represents Replication Server, the Sybase server program that maintains replicated data on a local-area network (LAN) and processes data transactions received from other Replication Servers on the wide-area network (WAN).
This icon represents Adaptive Server, the Sybase data server. Data servers manage databases containing primary or replicate data. Replication Server also works with SQL Server and with heterogeneous data servers, so, unless otherwise noted, this icon can represent any data server in a replication system.
This icon represents a Replication Agent, a replication system process or module that transfers transaction log information for a primary database to a Replication Server. The Replication Agent for Adaptive Server is RepAgent; the Replication Agent for Sybase SQL Server is Log Transfer Manager (LTM). Sybase provides Replication Agent products for Adaptive Server Anywhere, DB2, Informix, Microsoft SQL Server, and Oracle data servers.
Except for RepAgent, which is an Adaptive Server thread, all Replication Agents are separate processes. In general, this icon only appears when representing a Replication Agent that is a separate process.
This icon represents a client application. A client application is a user process or application connected to a data server. It may be a front-end application program executed by a user or a program that executes as an extension of the system.
This icon represents Sybase Central’s Replication Server Manager (RSM), a software tool that lets a Replication System Administrator monitor, analyze, troubleshoot, and administer a replication system.
RSM consists of:
An RSM Client (Sybase Central + the Replication Server plug-in): an Open Client application that lets you monitor, diagnose, and manage your replication system. The RSM Client includes a graphical user interface (GUI) integrated with Sybase Central.
An RSM Server: an Open Server application that translates and communicates requests from an RSM Client. The RSM Server also monitors for and responds to replication system events.
