Introduction

This guide offers Red Hat's policies and requirements for managing a SAP NetWeaver application server instances with a RHEL High Availability cluster. Users of RHEL High Availability clusters should adhere to these policies to be eligible for support from Red Hat with the appropriate product support subscriptions.

Policies

Scope of Red Hat support with SAP software resources managed by a cluster: Refer to Red Hat's policy on Management of applications that Red Hat does not ship for further details on Red Hat's scope of support applicable to SAP software deployments in a RHEL High Availability cluster.

The focus of Red Hat's assistance may be limited to functionality of the High Availability software and the SAP resource-agent(s). In some cases, SAP's input may be necessary to diagnose the nature of a problem, even if the problem originates in the resource-agent Red Hat ships. Solutions to problems with RHEL High Availability + SAP NetWeaver application server instances may depend on some input or deliverable from SAP in cases where the issue cannot be solved adequately through RHEL High Availability without SAP's assistance.

Red Hat subscriptions for SAP NetWeaver support: Red Hat provides support for RHEL High Availability's resource-agents managing SAP NetWeaver deployments through the following subscriptions:

  • Red Hat Enterprise Linux for SAP Solutions
  • Red Hat Enterprise Linux for SAP Applications with the RHEL High Availability Add-On
  • Red Hat Enterprise Linux for SAP with High Availability and Update Services

One of these subscriptions is required for Red Hat to assist with RHEL High Availability management of SAP NetWeaver application server instances.

Supported platforms for SAP NetWeaver application server instances with the RHEL HA Add-On: Red Hat support for its software supporting the SAP NetWeaver solution stack, including RHEL High Availability and its resource-agents for SAP software, largely follows the policies laid out for RHEL High Availability and RHEL:

However, in public cloud deployments, Red Hat support for HA cluster setups for managing SAP NetWeaver application server instances is currently limited to the following cloud platforms:

  • Amazon Web Services Elastic Cloud (AWS EC2)
  • Google Cloud Platform (GCP)
  • Microsoft Azure

Other cloud platforms are not supported by Red Hat for this solution at this time. Contact Red Hat Support if you are interested in running SAP NetWeaver on another cloud platform.

Supported releases of SAP NetWeaver: Red Hat provides support for RHEL High Availability management of the following NetWeaver products:

  • SAP NetWeaver Application Server for ABAP 7.X
  • SAP NetWeaver Application Server JAVA 7.X
  • SAP NetWeaver Application Server with ABAP and Java 7.X (Dual-Stack)

ABAP/JAVA Dual-Stack Support:
Because SAP no longer recommends dual-stack setups where ABAP and JAVA instances share the same SID, a Dual-Stack Split is required so that the ABAP and JAVA stack use separate SIDs. With such a setup, the Standalone approach for managing the ASCS/ERS instances for the ABAP stack and the SCS/ERS instances for the JAVA stack can be used.
For the HA cluster it is necessary to configure separate resource groups for each instance and set up appropriate constraints based on the separate SIDs for each part of the environment.

Supported Databases for SAP NetWeaver managed by RHEL High Availability: Red Hat supports RHEL High Availability management of SAP NetWeaver with any of the following database types for NetWeaver using the SAPDatabase resource agent:
