Business Continuity for SAP on IBM System z
A solution providing automation, high availability, and disaster recovery for SAP on IBM System z
Business Continuity of an SAP production system is a critical business factor. It requires the highest possible level of system availability and data consistency.
Continuous availability combines the characteristics of high availability (the ability to avoid unplanned outages by eliminating single points of failure) and continuous operation (the ability to avoid planned outages, such as for administrative or maintenance work). The goal is to keep the SAP system running 24x365.
The IBM Business Continuity solution is a set of best practices to help ensure business continuity for your SAP on System z environment. These best practices are continuously being extended and verified to exploit applicable new features and functions of SAP applications, and other software and hardware.
The objectives of the IBM Business Continuity solution for SAP are:
The IBM Business Continuity solution for SAP is based on Geographically Dispersed Parallel Sysplex™ (GDPS®) which in turn is based on DB2 data sharing and IBM Tivoli® System Automation for z/OS (SA z/OS). SA z/OS provides the means for fully automating the management of all SAP components and related products running on z/OS, AIX, Windows, or Linux.
This integration with IBM Tivoli System Automation is a major aspect of the SAP on DB2 Business Continuity solution. IBM Tivoli System Automation for z/OS (SA z/OS), IBM Tivoli System Automation for Multiplatforms (SA MP) and IBM Tivoli System Automation Application Manager for z/OS (SA AM), ensure high availability of systems and databases. System Automation automatically discovers system, application, and resource failures in a cluster. It uses sophisticated, policy-based knowledge about application components and their relationships, and availability goals to decide on corrective actions within the right context. SA z/OS manages availability of business applications, running in single systems and clusters under z/OS, whereas SA MP does the same for single systems and clusters under Linux for System z, AIX, and others. SA AM is the end-to-end management application. It enables you to manage your heterogeneous SAP solution from a single application.
The IBM publication Business Continuity for SAP on IBM System z describes the IBM Business Continuity solution for SAP on System z.

Tivoli System Automation best practice policies for SAP on System z
These policies have been developed based on recommendations in the documentation Business Continuity for SAP on IBM System z.
In order to control the SAP on IBM System z solution the automation software needs specific scripts, for example to start, stop, or monitor all SAP components. The SA z/OS policies are shipped with the product.
Customers running SAP on System z may additionally order the SA MP best practice policies on an "as is" basis, together with a sample for SA AM. They will be sent as a zip file (zSAP_BusinessContinuity.zip).
