SAP Replication Server

An SAP Replication Server at each site coordinates data replication activities for local data servers, and exchanges data with SAP Replication Servers at other sites.

An SAP Replication Server:

Receives primary data transactions from databases via Replication Agents and distributes them to sites with subscriptions for the data
Receives transactions from other SAP Replication Servers and applies them to local databases

SAP Replication Server system tables store information needed to accomplish these tasks. The system tables include descriptions of replication definitions and subscriptions, security records for SAP Replication Server users, routing information for other sites, access methods for the local databases, and other administrative information.

SAP Replication Server system tables are stored in an SAP ASE database called the Replication Server System Database (RSSD), or an SAP SQL Anywhere database called the Embedded Replication Server System Database (ERSSD). An RSSD or ERSSD is assigned to each SAP Replication Server. An SAP ASE data server with an RSSD can also store application databases. For more information, see the Administration Guide Volume 1.

Use Replication Command Language (RCL) to manage information in SAP Replication Server. You can execute RCL commands, which resemble SQL commands, on SAP Replication Server using isql, the SAP interactive SQL utility. The Reference Manual is the complete reference for RCL.
