RMA Replication Architecture

Each site, whether primary or replicate, contains a database and optionally a portion of the replication software. Each site contains replication software and an RMA instance that provides local access to the host system, when needed.

Replication is set up to support replication in one direction between the primary and replicate. In a typical replication scenario, the SAP application connects to and updates data on the primary site. The replication software captures transactions, and replicates to the replicate site.

During the initial setup and configuration, you connect to the RMA client on the primary or replicate site, and issue commands or follow instructions to define the environment and set up replication. After the replication environment is set up, you can also connect to an RMA client on either site to monitor and administer the replication environment.

Your replication software may be installed on multiple servers. It is often advantageous to install the Replication Agent on the same host as the primary database, and the SAP Replication Server on the same host as the replicate database. This spreads processing across multiple servers and allows database communication to be near the database that is being communicated with, allowing local client library installations to be used. However, you can install the replication software on the same host or totally separate hosts, as all communication is over TCP/IP. The replication environment diagram is just one example.
