Customizing SAP for high availability
The subtopics that are contained in this information unit describe the set-up of SAP to run as a high availability SAP solution.
You can also find detailed SAP documentation about how to install and use the SAP Central Services under:
SAP NetWeaver 7.1 and newer releases are delivered with the following high availability-related changes. These changes must be taken into account in the IBM Z System Automation best practice policy for SAP. The changes are:
- The ZSCSinst tool supports the installation of SAP ERS for ABAP and Java™ as individual SAP instances, including ERS instance profiles.
- There is now only one profile per instance that contains all the information, which was previously spread across two separate profiles, the instance profile and the instance start profile.
The Solution Manager Diagnostics Agent (SMDA) is a component of the SAP Solution Manager system landscape. For newer SAP NetWeaver releases, the SMDA is installed automatically together with the SAP application server instance. For installation details, see the SAP Installation Guide for your SAP application server platform.
With Software Provisioning Manager 1.0 SP09 or higher, you can install the SMDA instance on z/OS® as a stand-alone engine with the ZSCSinst tool and set up the Solution Manager connection automatically during the installation (see How to install and set up the SMDA instance on z/OS).
From a high availability point of view, the function of the SMDA is not seen as a single point of failure. For z/OS, the automation policy for the SMDA is described in Customizing IBM Z System Automation.
