Overview
The Administration Server is the central point from where you configure and manage all resources in the domain. Usually, you configure
a domain to include additional WebLogic Server instances called Managed Servers.
Managed Servers host business applications, application components, Web services,
and their associated resources and the Administration Server is used for configuration
and management purposes only. The Administration Server operates as the central
control entity for the configuration of an entire domain. In each domain, one
WebLogic Server instance acts as the Administration Server—the server instance
which configures, manages, and monitors all other server instances and resources
in the domain. Each Administration Server manages one domain only. A Managed Server is an Oracle WebLogic Server instance that retrieves its configuration
data from the domain's Administration Server. There can be multiple Managed Servers in a domain, but only one Administration Server.
You are an application server administrator in Dizzyworld
Corporation. The Dizzyworld system architects have decided to simulate the production
environment by configuring Managed Servers for the dizzyworld domain to host
business applications and use the Administration Server to configure and monitor
Managed Servers.
To configure the Managed Servers, perform the following steps:
1.
In the Oracle WebLogic Server Administration Console,
in the Domain Configurations section, click Servers.
2.
Notice that the Summary of Servers section appears. You can view here
the Administration server and the Managed Servers listed for the defined
domain. Next, click dizzy1.
3.
The settings for dizzy1 section are displayed. From the left pane, in
the Change Center section, click Lock & Edit.
4.
In the Settings for dizzy1 section, scroll down to select the SSL
Listen Port Enabled check box and enter the SSL Listen Port as 7004.
5.
Scroll down and click Save.

You can now view the message for Settings updated successfully.
Next, under the Domain Structure section, click Servers.
7.
Click dizzy2. Scroll down to select the SSL Listen Port Enabled
check box and enter the SSL Listen Port as 7006.
8.
Scroll down and click Save.

You can now view the message for Settings updated successfully.
To add a new Managed Server from the Oracle WebLogic Console,
