Installing SAP Mobile Platform in a Simple Load-Balancing Cluster

This installation scenario places a data tier on one server and two or more SAP Mobile Server instances on separate servers. Components work together as a cluster, providing load balancing between the SAP Mobile Server instances. This scenario is suitable for a low-volume production environment that does not require a failover capability for the data tier.

Prerequisites

The architecture, design characteristics, and use cases for this installation scenario are described in Landscape Design and Integration > Designing the Landscape > Simple Load-Balancing Cluster . The installation instructions in this chapter assume that you have used the Landscape Design and Integration document to design the landscape

This diagram illustrates the system you are installing:


Simple Load Balancing Cluster
Note: You cannot install cluster nodes concurrently. You must install the nodes in this cluster in this order:
  1. Install the data tier.
  2. Install the primary SAP Mobile Server as an application server node.
  3. Install the secondary SAP Mobile Server as an application server node.
  4. (Optional) Install SAP Mobile Server scale-out nodes as needed. You can install multiple scale-out nodes, one at a time, in any order.
Task
  1. Installing the Data Tier
    This installation scenario places SAP Mobile Platform common data tier resources on a separate host, from which they can be shared by multiple SAP Mobile Server instances.
  2. Installing the SAP Mobile Server
    Install all of the SAP Mobile Server nodes in your simple load-balancing cluster. This scenario uses two SAP Mobile Servers as application server nodes, and (optionally) as many scale-out nodes as necessary.
  3. Verifying the Full SAP Mobile Platform Cluster Installation
    When you have completed installing and verifying all cluster nodes, verify the functionality of the full cluster to ensure that the installation process has been completely successful.
