SAP NetWeaver Application Server: High Availability


This section looks at the SAP NetWeaver Application Server (AS) from the viewpoint of high availability.

This part of the documentation describes issues that affect both the ABAP and Java aspects of the SAP NetWeaver Application Server.

For more information on issues that affect only the ABAP or only the Java aspects, see:

·         SAP NetWeaver Application Server ABAP: High Availability

·         SAP NetWeaver Application Server Java: High Availability

For more information on SAP NetWeaver technical infrastructure and on usage types other than AS-ABAP and AS-Java, see the Technical Infrastructure Guide: SAP NetWeaver 2004s, which you can find on SAP Service Marketplace at

Implementation Considerations

For detailed technical guidance when implementing a specific feature, contact the appropriate source, such as your SAP consultant, or SAP Safeguarding.


High availability for the SAP system should be part of a system-wide strategy. Therefore, be sure to also consider other components of the system, such as the database management system (DBMS), the network, and the hardware and operating system services.
