HA for SAP NetWeaver Overview

The SAP NetWeaver platform consists of the following components:

Each component can be treated as a specific instance. Each instance has its own controlling process named sapstartsrv.

The SAP NetWeaver platform can be deployed as an ABAP, a JAVA, or a dual stack. In the dual stack, the primary application instance and the dialogue instance combine the ABAP and the JAVA processes in one instance. The central services and the replicated enqueue server implement either the ABAP or the JAVA deployment only.


Caution

Caution - For a detailed description of the SAP NetWeaver platform in the High Availability environment, see the SAP documentation at http://service.sap.com/ha. In particular, study the section that provides an overview of the architecture of the SAP NetWeaver to be certain that you understand the basic concepts of your version of the SAP NetWeaver.


To eliminate potential single points of failure in an SAP NetWeaver platform, HA for SAP NetWeaver provides fault monitoring, automatic restart, and automatic failover for the components of the SAP NetWeaver platform.

The primary and additional dialogue instances can be configured as multiple master or failover deployments. All other instances must be failover deployments.

Each component of the SAP NetWeaver platform has a data service that protects the component in an Oracle Solaris Cluster configuration, as described in the following table.
