IBM Enterprise Workload Manager Release 1

32 IBM Enterprise Workload Manager

The wizard suggests that if you do not need the installation wizard any longer, you might

remove the Install directory to save space.

You are now ready to configure the domain manager and associated WebSphere Application

Server instance.

2.4 EWLM configuration in our ITSO environment

After you finish installing the domain manager and managed servers you need to perform

additional configuration tasks. These include configuring the domain manager, the managed

servers and firewall brokers, starting WebSphere Application Server, and starting the EWLM

elements.

In this section, we first go through the configuration steps for our domain manager running on

Linux. After we can log on successfully to the EWLM Control Center, we transfer the EWLM

code to our managed servers running on AIX and Windows and configure each of these. This

is also the order you should follow when setting up your Enterprise Workload Manager

environment.

In Section 2.5, “Installing the domain manager on other operating systems” we guide you

through the differences if your domain manager is running on AIX, Windows or i5/OS. In

Section 2.6, “Configuring managed servers on other operating systems” we provide

information on managed server issues on other operating systems including i5/OS and

Solaris.

We need to complete the following steps to configure EWLM in our environment:

򐂰 Configure the domain manager.

򐂰 Create users for administrating EWLM.

򐂰 Start the WebSphere Application Server instance on the domain manager.

򐂰 Configure the managed server.

򐂰 Enable ARM services on the operating system.

2.4.1 Configuring domain manager on Linux

Our domain manager runs on Red Hat Enterprise Linux AS 2.1. As part of the installation

process of the Virtualization Engine install, directory /opt/IBM/VE is created. Its size is

approximately 1.3 GB. The EWLM installation creates a subdirectory EWLM; Example 2-1

shows the structure of the subdirectory /opt/IBM/VE/EWLM/bin where EWLM configuration

scripts and associated log files are located. These log files are named after their creation

scripts and provide useful information for debugging events. We go through a detailed

explanation of many of these scripts when we explain the configuration steps for our domain

manager and managed servers.
