IBM Domino Application Server

 

1Introduction

IBM® Domino is an advanced platform for hosting social business applications. It delivers scalable, security rich applications at a low cost. This improves productivity and enhances decision making. Its main features include:

  • Low ownership costs: By minimizing administration requirements through automation, staff can focus on higher value tasks
  • Minimal infrastructure: By using less power for providing data storage, network band width and servers, you reduce costs
  • Rich application environment: Supporting workflow-driven and people-oriented applications that help a wide variety of business operations deliver enhanced results
  • High availability: Features advanced clustering, replication, server fault recovery and automated diagnostic tools

The KEMP LoadMaster is used to load balance the Domino workload. The LoadMaster offers advanced Layer 4 and Layer 7 server load balancing, SSL Acceleration and a multitude of other advanced Application Delivery Controller (ADC) features. The LoadMaster intelligently and efficiently distributes user traffic among the application servers so that users get the best experience possible.

1.1Document Purpose

This document provides the recommended LoadMaster settings used when load balancing the Domino workload. The KEMP Support Team is available to provide solutions for scenarios not explicitly defined. The KEMP support site can be found at: https://support.kemptechnologies.com

1.2Intended Audience

This document is intended to be read by anyone who is interested in configuring the LoadMaster to optimize Domino Application Server.

2Domino Template

KEMP has developed a template containing our recommended settings for Domino. You can install this template on the LoadMaster and use it when creating Virtual Services. Using a template automatically populates the settings in the Virtual Services, which is quicker and easier than manually configuring each Virtual Service. If needed, you can make changes to any of the Virtual Service settings after using the template.

Download released templates from the Templates section on the KEMP documentation page: http://kemptechnologies.com/documentation/.

For more information and steps on how to import and use templates, refer to the Virtual Services and Templates, Feature Description.

For steps on how to manually add and configure each of the Virtual Services, refer to Section 4 of this document.

4Configure the LoadMaster

The deployed Domino environment determines which of the following setups is used.

4.1Enable Subnet Originating Requests Globally

It is best practice to enable the Subnet Originating Requests option globally.

In a one-armed setup (where the Virtual Service and Real Servers are on the same network/subnet), Subnet Originating Requests is usually not needed. However, enabling Subnet Originating Requests should not affect the routing in a one-armed setup.

In a two-armed setup where the Virtual Service is on network/subnet A, for example, and the Real Servers are on network B - Subnet Originating Requests should be enabled on LoadMasters with firmware version 7.1-16 and above.

When Subnet Originating Requests is enabled, the LoadMaster routes traffic so that the Real Server sees traffic arriving from the LoadMaster interface that is in that network/subnet.

When Subnet Originating Requests is enabled globally, it is automatically enabled on all Virtual Services. If the Subnet Originating Requests option is disabled globally, you can select whether or not to enable Subnet Originating Requests on a per-Virtual Service basis.

To enable Subnet Originating Requests globally, follow the steps below:

  1. In the main menu of the LoadMaster WUI, go to System Configuration > Miscellaneous Options > Network Options.

Figure 4‑1: Subnet Originating Requests

  1. Select the Subnet Originating Requests check box.

4.2Enable Check Persist Globally

It is recommended that you change the Always Check Persist option to Yes – Accept Changes. Use the following steps:

  1. Go to System Configuration> Miscellaneous Options > L7 Configuration.

Figure 4‑2: Enable Check Persist Globally

  1. Click the Always Check Persist dropdown arrow and select Yes – Accept Changes.
