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:

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.
