208 IBM Enterprise Workload Manager
Possible causes of this problem are the following:
EWLM Control Center is supported on IE V6 SP1. If you are on a previous version, it may
work, but you may have intermittent problems.
You need to enable cookies.
Do not set security to the maximum on IE because this renders your login unsuccessful.
You need a JVM plug-in to display graphs.
The EWLM Control Center uses SSL/TLS for communications.
We recommend you scan your computer and install all critical Internet Explorer updates.
For example, from Internet Explorer, choose Tools
→ Windows Update. This will take
you to the Microsoft Window Update internet site. Click Scan for updates. Apply the
latest critical updates, including KB831167, which is needed to allow a valid userid to log
in without first waiting one full minute after presentation of the login page.
You need to set the security in your browser to use TLS. To do this follow these steps:
a. In IE, click Tools
→ Internet Options → Advanced.
b. Scroll down to Security and select Use TLS 1.0.
c. Click OK.

Application topology window does not show expected results.
The Application topology for our transaction class did not show our entire topology. The
Application Topology window should have looked similar to Figure 8-2 since we had an HTTP
Server as hop 0, two WebSphere Application Servers as hop 1, and the DB2 Universal
Database as hop 2 in our configuration. However, when we selected Application Topology
from the pull-down list from the Monitor
→ Transaction Class selection, we got a view that
looked either like Figure 8-3 (missing the DB2 hop) or Figure 8-4 (missing the HTTP hop).
Figure 8-2 Correct Application Topology view
