i Preface The product SAP NetWeaver Identity Management Identity Center is the primary component for identity management. The Identity Center includes functions for identity provisioning, workflow, password management, logging and reporting. It uses a centralized repository, called the identity store, to provide a uniformed view of the data, regardless of the data's original source. The reader This manual is written for people who need an overview of the minimum system requirements for SAP NetWeaver Identity Management Identity Center. Prerequisites To get the most benefit from this manual, you should have the following knowledge: Knowledge about SAP NetWeaver Identity Management Identity Center.

Introduction SAP NetWeaver Identity Management Identity Center Minimum System Requirements 1 Introduction This document describes the minimum production system configuration. This description does not consider sizing of the systems. The description assumes that you will be using a test system to develop and test new configurations, and a production system, which is the live system. Whether the test system connects to the live data sources, or dedicated data sources are used for development and testing is an implementation design issue. There are separate sections for SAP NetWeaver Identity Management Identity Center 7.0 and 7.1/7.2 to cover the differences between the versions.
2 SAP NetWeaver Identity Management Identity Center 7.1/7.2 SAP NetWeaver Identity Management Identity Center Minimum System Requirements SAP NetWeaver Identity Management Identity Center 7.1/7.2 This section describes a system using SAP NetWeaver Identity Management Identity Center 7.1 or 7.2. Production system Assuming that the production system has high availability requirements, a single point of failure must be avoided. Therefore, the components are clustered or duplicated. There are four main components of the system: Database (DB). The database is either a Microsoft SQL Server or Oracle database. The system platform is any which is supported by the selected database. There should be at least two physical servers in a cluster for this. The Identity Center does not require a dedicated database server (unless sizing requirements demand it), so you may be able to use existing database instances. Please note the installation and configuration requirements for the database, as found in the installation guides (SAP NetWeaver Identity Management Identity Center: Installing the database (Microsoft SQL Server/Oracle)). User Interface (UI). This is the end-user and administrator front-end, which runs on SAP NetWeaver AS Java. High availability is handled by SAP NetWeaver. The Identity Center does not require a dedicated NetWeaver, so existing instances may be used. Runtime Components (RT). For high availability reasons, there must be at least two RT servers. See the installation guide for supported platforms (SAP NetWeaver Identity Management Identity Center Installation overview). Dedicated servers are not required, so you may be able to use existing servers for this. The number of RT servers and their placement in the network depends on the identity management topology and network topology. Management Console (MC). This is the developer/it administrator console, running on Microsoft Windows, using the Microsoft Management Console. There will normally not be any high availability requirements on this component, which can be installed on any Microsoft Windows server, and requires very little resources. A dedicated server is not necessary.
SAP NetWeaver Identity Management Identity Center 7.1/7.2 SAP NetWeaver Identity Management Identity Center Minimum System Requirements 3 Test system The test system must contain the same components as the production system, but high availability is not required, and also the performance demands will be lower, so all components may be installed on the same Microsoft Windows server. Or they can be installed on different systems, if that is more convenient. Synchronizing the configuration It is assumed that all configuration changes are first tested on the test system, and then transported to the production system. This is documented in the staging document (SAP NetWeaver Identity Management Identity Center Implementation Guide Staging environment). Backup As the Identity Center stores all configuration information in the database, this is the only component which needs to be backed up. Please see the backup and restore procedures for the relevant database for details on these operations.
4 SAP NetWeaver Identity Management Identity Center 7.0 SAP NetWeaver Identity Management Identity Center Minimum System Requirements SAP NetWeaver Identity Management Identity Center 7.0 The requirements for 7.0 are similar to that of 7.1 and 7.2. Only the differences are documented here: Production system The only difference in the production system is that version 7.0 uses a web server with PHP instead of SAP NetWeaver. This means that high availability must be set up separately. If running on Microsoft Windows, the Microsoft Windows Load Balancing System (WLBS) may be used. For other systems, refer to the relevant web server high availability documentation. In addition, the Monitoring interface is separate from the workflow interface. This may be installed on the same server as the Workflow web interface, to achieve high availability for the Monitoring as well. Test system The test system must have PHP to be able to run workflow and monitoring.
