5.2 Assessment

Before we can design and plan our EWLM domain we need to assess our environment. This

is the first step to develop a domain policy. At this stage, we assess the servers and

applications of the ITSO environment. The design of your domain policy is dependent on the

number of platforms, applications, workloads, and, in some situations, the Service Level

Agreements you have, which makes this phase a very important one.

The assessment phase involves the following steps:

1. Defining the EWLM domain

2. Identifying all servers and middleware

3. Identifying all applications

5.2.1 Defining the EWLM domain

The first step of the assessment phase is to define an EWLM management domain and its

boundary. Table 5-2 and Table 5-3 provide a simple overview of our EWLM management

domain, which is the foundation for our domain policy planning.

The EWLM domain definition contains the following attributes:

򐂰 EWLM domain name and description

򐂰 Servers, which will be managed servers, and a simple description of each

You can see the EWLM domain name in the title bar of the EWLM Control Center in the

browser window; this is shown in Figure 5-1.
