IBM Enterprise Workload Manager Release 1

22 IBM Enterprise Workload Manager

Figure 2-3 ITSO environment

As you can see, we have a firewall integrated in our ITSO environment. In this chapter,

however, we describe the setup of our domain manager and the managed servers using

default settings only. We integrated security and firewall settings at a later time, after we had

our configuration set up. The changes we made to the environment for security purposes are

described in Chapter 6, “Using a firewall and securing EWLM” on page 155.

2.3 Virtualization Engine suite

For this release, Enterprise Workload Manager is an optionally installable system service of

the IBM Virtualization Engine. You can install EWLM domain manager, EWLM managed

servers for IBM and non-IBM platforms, Single-System EWLM, or some combination of

these. The available options are explained in this section and depend on the package you

have purchased and on the operating systems in your environment. Single-System EWLM is

only available on AIX and i5/OS. The Single-System EWLM option was not explored as part

of the redbook project. The EWLM Control Center is installed as part of the domain manager

installation. The managed server installation includes a firewall broker installation image.

We describe the EWLM installation in this section. After the installation is complete, you must

run a set of configuration scripts to get the domain manager, EWLM Control Center, and

managed servers up and running. Our discussion of the configuration process is divided into

two parts:

򐂰 First, we describe the installation and configuration of the domain manager and managed

servers in our ITSO environment. This includes:

– Domain manager on Linux

– Managed servers on AIX and Windows

Chapter 2. Installing and configuring EWLM 23

򐂰 Second, we concentrate on the differences when installing and configuring EWLM code

on the domain manager and managed servers on all other supported operating systems.

This is explained in Section 2.5, “Installing the domain manager on other operating

systems” and 2.6, “Configuring managed servers on other operating systems” and

includes:

– Domain manager on Windows, AIX and i5/OS

– Managed servers on i5/OS and Solaris

Table 2-1 provides an overview of user roles required on each operating system in order to

install and configure EWLM, operate as WebSphere Application Server administrator, and for

mapping users to the EWLM Control Center. Details for each operating system are provided

in the appropriate sections in this chapter.
