About this document This white paper outlines the ideal way to successfully install the IBM WebSphere Application Server (WAS) 7.0.0.9 and EMC® Documentum®

Business Activity Monitor server in a clustered environment. In addition, this document describes the process of configuring IBM WAS 7.0.0.9 with the Documentum Business Activity Monitor server to enable high availability and load balancing.

This white paper describes the installation and configuration processes on a single machine. Since the volume of incoming requests is high in a production environment, the load can be handled in an efficient manner if the web application is deployed in a clustered environment.

Audience

This white paper is intended for administrators and developers who deploy the Documentum Business Activity Monitor server on the IBM WebSphere Application Server in a clustered environment. This document contains step-by-step procedures to install and configure the WAS cluster, install and configure IBM HTTP Server, and deploy and configure the Business Activity Monitor server in a clustered environment to achieve high availability and load balancing.

Introduction

Documentum Business Activity Monitor (BAM) collects and stores process execution data, prepares the data for reporting, and provides a real-time dashboard display environment. The Business Activity Monitor component Process Reporting Services (PRS) is a tool for generating and formatting reports and alerts displayed in the dashboard.

This white paper discusses how high availability and load balancing are achieved in BAM if IBM WebSphere Application Server 7.0 is installed and configured in a clustered environment.

The process of installing and configuring IBM WebSphere Application Server 7.0 on a single machine in a clustered environment includes the following steps:

Installing IBM WebSphere Application Server Network Deployment 7.0

Installing IBM Update Installer for WebSphere 7.0.0.9

Installing IBM HTTP Server

Installing the Business Activity Monitor WAR file in a cluster setup The BAM server is deployed on two nodes. However, the BAM server is passive (deactivated) on one of the nodes. The BAM cluster can work only in a sticky session configuration.



High-availability, failover, and load balance

High-availability clusters (also known as HA Clusters or Failover Clusters) are web clusters that use load balancing to send requests to available servers. If a server fails, it is automatically removed from the available server’s pool and your requests are sent to servers capable of serving your request.

Load balancing is achieved by sharing applications’ load between multiple servers to decrease the needed resources on each server, and improve the performance for end users.

Configuring the Business Activity Monitor server to work in a cluster

You must perform the following tasks to configure high availability and load balancing on the BAM server:

Retaining the 6.5 SP2 BAM server in the waiting state Configuring BAM in a sticky session of IBM WebSphere Application Server

Retaining the 6.5 SP2 BAM server in the waiting state

Access one of the BAM servers, and modify the value of the <activateOnStartup> parameter to “false” in the env-config.xml, to pause the server.

Note: This setting is valid for the 6.5SP2 release only.

However, in later versions of BAM (post 6.5 SP2), a special automatic mechanism checks whether the other BAM server is running on the same database. At startup, the BAM server must identify if the other server is running on the same database. In this case, the server that was last started does not execute its logic and remains in the waiting state.

Configuring BAM in a sticky session of IBM WebSphere Application Server

Only one BAM server can work with the database that the BAM server must configure to run in a sticky session. The sticky session provides uninterrupted access to the reports functionality.

The sticky_session property specifies the cluster behavior for HTTP sessions. Each request is load balanced between node1 and node2. However, when a user opens a session on one server, it is recommended to always forward this user's requests to the same server. This is called a "sticky session," since the client always uses the same server the user reached on the first request. Otherwise, the user's session data must be synchronized between both servers.

Perform the steps provided in this section to configure the IBM WebSphere Application Server for BAM in a sticky session.

To configure BAM in a sticky session of IBM WebSphere Application Server: 1. Navigate to the following location:

<IBM Installed Directory>\HTTPServer\Plugins\config\webserver1



2. Edit the plugin-cfg.xml file as follows:

<ServerCluster CloneSeparatorChange="false" GetDWLMTable="false" IgnoreAffinityRequests="false" LoadBalance=" Random" Name="cluser1" PostBufferSize="64" PostSizeLimit="-1" RemoveSpecialHeaders="true" RetryInterval="60">

Configuring the IBM WebSphere Application Server for BAM

The IBM WebSphere Application Server must be configured before you deploy the BAM application. The configuration process involves copying files in the WebSphere directory. Use the WebSphere Application Server Administration Console to deploy the BAM application.

Note: (Relevant only to 6.6 and 6.7) Before you deploy the BAM server on IBM WebSphere version 7.0.0.x, you must replace the jaxen-full.jar available in the bam-server.war/WEB-INF/lib folder with the jaxen-full.jar file available in the bam-product-supplemental_files.zip/WebSphere/7.0.0.7/Required jars folder. Ensure that you replace this file prior to repacking the bam-server.war file.

Follow the instructions provided in this section to configure the IBM WebSphere Application Server before you deploy the BAM application on it.

To configure the IBM WebSphere Application Server: 1. Change the directory to [WebSphere root]/optionalLibraries.

2. Create the BAM folder.

3. Copy the following jar files to the BAM directory:

[Temporary WAR location]\bam‑server.war\WEB-INF\lib\aspectjrt.jar

[Temporary WAR location]\bam‑server.war\WEB-INF\lib\saaj-api.jar

[Temporary WAR location]\bam‑server.war\WEB-INF\lib\saaj-impl.jar

[Temporary BAM setup folder]\BAM Server\WebSphere\Required JARs\xalan.jar and xercesImpl.jar

4. In the WebSphere Administration Console, select Environment > Shared Libraries.

5. In the Scope drop-down list, select Cell=Cell_Name.

6. Perform the following steps to create a shared library for each jar file you copied:

a. Select New.

b. Type the library name.

c. In the Classpath field type ${WAS_INSTALL_ROOT}/optionalLibraries/BAM/[jar_name].

d. Select Apply and Save.

7. Download the Business Activity Monitor (bam-server.war) file from the ftp site.

8. Save the bam-server.war file in the temp folder.

applications. The Enterprise Applications page appears.

2. Select the checkbox next to the bam-server application.



3. Click the bam-server link.

4. In the General Properties page, click the Class loading and update detection link.

5. Specify 120 seconds in the Polling interval for updated files field.
