Implementing High Availability in the Processing Tier

Processing servers and their services have to be secured for high-availability. SAP BusinessObjects BI Platform 2025 servers support only the load-balancing technology and doesn't support active/passive technology. So you can create additional servers of the same type for setting up servers redundancy.

Considerations:

• High availability can be achieved in the processing tier by including more servers in your deployment.
• To achieve high availability in the processing tier, add one or more of the following servers to your organization’s deployment:

  • Adaptive Processing Servers of the type of service(s) needed for your implementation

  • Crystal Reports Cache Servers

  • Crystal Reports 2025 Processing Servers

  • Web Intelligence Processing Server

When you create a new additional server of any type, you can add it manually from the CMC. For new Adaptive Processing Servers (APS), you can use the System Configuration Wizard from CMC to add them automatically and quickly by using predefined deployment templates.

System Configuration Wizard:

• The wizard helps you with the basic configurations of your SAP BusinessObjects BI Platform 2025 system, including configuring APSs according to set deployment templates.
• The APS configuration given by the wizard is a good starting point; however, system sizing must still be performed.
  Note

  Selecting a deployment template in the wizard or manually creating more APSs doesn't replace system sizing. For more information about BI sizing:

  Sizing Guide

• The wizard is available from the Central Management Console (CMC).
• For a detailed description of the deployment template, click the deployment template link on the Capacity page of the wizard to open the DeploymentTemplates.pdf file.

Features of the System Configuration Wizard:

The following are features of the System Configuration Wizard:

• Simple workflow to do initial server configuration of the BI system

• Command-line facility to enable preset configuration

• Installation of more APSs that can be configured to meet requirements

The installation program installs one APS per host system. Depending on the features that you've installed, this APS can host many services, such as the Monitoring Service, Promotion Management Service, Multi-Dimensional Analysis Service (MDAS), Publishing Service, and others.

A generic server hosts a service responsible for processing requests from various sources.

For production or test systems, the best practice is to create more APSs, and then configures the APSs to meet your organization’s business requirements.
