Service Configuration for Failure Resilience

This section discusses how to protect a number of critical SAP NetWeaver ASservices that are not Single Points of Failure (SPOFs) by appropriate system configuration.

These services are implemented as work processes and, in principle, you can configure them redundantly by adding another work process of the same type, either on the same machine or on another SAP NetWeaver AS instance. Such redundancy is as important for high availability of an SAP NetWeaver AS system as switchover software.

For more information about configuring ABAP services, see SAP Note 39412, which includes general guidelines on how to configure work processes.
