Sun Cluster Software Example

Communications Suite product components that can be configured to run in a cluster instead of on a single server include Calendar Server, Messaging Server, and Instant Messaging.

This example installs Messaging Server in a Sun Cluster framework.

Before you install or configure Sun Cluster software, ensure that the combination of hardware and software that you choose for your cluster is currently a supported Sun Cluster configuration. For guidelines on implementing Sun Cluster software within a Communications Suite environment, refer to Chapter 2, Installing Software on the Cluster, in Sun Cluster Software Installation Guide for Solaris OS and also see Sun Cluster 3.1 8/05 With Sun Java Enterprise System 5 Special Instructions.

Requirements and Sequencing Issues

Messaging Server requires Directory Server, but not necessarily a local copy. You will need the Sun Cluster Core component as well as the Sun Cluster Agents for Directory Server and Messaging Server. If a remote Directory Server is used, then the Sun Cluster Agent for Directory Server is not required.

Installing, configuring, and starting the product components in the correct order is crucial for a successful Sun Cluster implementation.

1. Installing the Sun Cluster product component

2. Configuring the Sun Cluster framework

3. Installing the additional product components that are required for Messaging Server to operate in the cluster

4. Configuring the Sun Cluster data services using the agents for the relevant product components

At least two installation sessions are performed on each node in the cluster.

Phase I. Installing and Configuring the Sun Cluster Framework

The following tasks must be performed on all nodes in the cluster.

To Develop a Sequence for the Sun Cluster Framework

1. Verifying that the hardware is connected correctly for the cluster

   • Sun Cluster 3.0–3.1 Hardware Collection for Solaris OS (SPARC Platform Edition) http://docs.sun.com/coll/1024.1

   • Sun Cluster 3.0–3.1 Hardware Collection for Solaris OS (x86 Platform Edition) http://docs.sun.com/coll/1142.1

2. Checking the installation sequence guidelines

   Check to see what guidelines apply to this example and make adjustments as needed.

3. Checking the installation prerequisites

   Check to see what tasks you might need to perform for this installation before starting.

4. Running the installer

   On Solaris 10, Sun Cluster software can only be installed in the global zone.

5. At component selection, choosing only the Sun Cluster product component

   ---

   Tip –

   During a Configure Now installation (usually where you have chosen to install all product components), you are prompted whether to enable support for remote Sun Cluster configuration. If you select Yes, postinstallation configuration for Sun Cluster software will be easier.

   ---

6. Selecting the Configure Later type

7. If needed, manually installing the Sun Cluster support for additional features: RSMAPI (SUNWscrif), SCI-PCI adapters (SUNWsci), RSMRDT drivers (SUNWscrdt)

   Refer to the Sun Cluster Software Installation Guide for Solaris OS for further information.

8. Following the instructions to configure the Sun Cluster Framework for each host in the cluster

   Follow instructions in Chapter 2, Installing Software on the Cluster, in Sun Cluster Software Installation Guide for Solaris OS. When the Sun Cluster documentation refers to a Sun Cluster CD-ROM, substitute the name of the equivalent Communications Suite CD-ROM.

   For documentation on creating resource groups and configuring data services, refer to the Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

Phase II. Installing and Configuring Product Components and Agents

The following tasks must be performed on all nodes in the cluster.

To Develop a Sequence for Configuring Product Components and Agents

1. Running the installer

2. At component selection, choosing the following:

   1. Messaging Server

      Directory Server and the Directory Preparation Tool are automatically selected.

      (Optional) If you are using a remote copy of Directory Server, deselect Directory Server and specify a remote copy when prompted.

   2. Sun Cluster Agents for Sun Java^TM System

      All agents are selected by default.

   3. Expanding the Sun Cluster Agents for Sun Java System product component and deselecting all agents except Directory Server and Messaging Server

3. Resolving incompatibilities

   The installer verifies software on your node and provides guidance if incompatibilities are identified.

4. Verifying installation directories

5. Selecting the Configure Now or Configure Later type

   Messaging Server and Sun Cluster Agents cannot be configured during installation.

6. Configuring all the selected product components except Sun Cluster Agents

   • Messaging Server Postinstallation Configuration

     When specifying installation directories, use a location on a cluster file system for Messaging Server.

7. Starting all the product components except Sun Cluster Agents, in this order:

   1. Starting and Stopping Directory Server

   2. Starting and Stopping Messaging Server

8. Configuring the data services for the product components you have installed and configured
