This topic provides step by step instructions for configuring a domain for
a cluster of WebLogic Servers. These instructions apply only to Windows installations
of Workshop. For information about cluster hardware configuration see Setting
up WebLogic Clusters in the WebLogic 8.1 documentation.
The tasks in setting up and deploying to a cluster are:
-
Select Start-->BEA WebLogic Platform 8.1-->Configuration
Wizard
-
In the Create or Extend a Configuration dialog, select
Create a New WebLogic Configuration. (Note the other options
are primary used for creating development environments, not production environments.).
- In the Select a Configuration Template dialog, select the
desired configuration template.
-
In the Choose Express or Custom Configuration dialog,
select Custom.
- In the Configure the Administration Server dialog, enter
the following information:
- Name
The Name must consist of alphanumeric characters with no spaces.
- Listen Address
For the information about populating the Listen Address field

Any port numbers between 1 and 65535 is valid.
-
SSL Enabled
Check this box if the applications you plan to deploy use SSL.
- In the Managed Server, Clusters, and Machines Options dialog,
click Yes.
- In the Configure Managed Servers dialog, enter the Name,
Listen Address, Listen Port, and SSL
Listen Port for each managed server you will to add to the domain.
- In the Configure Clusters dialog, enter the following information
for each cluster you wish to add to the domain:
-
Cluster Name
This gives the name of the cluster as a whole.
-
Cluster Multicast Address
Allowable values are in the range 224.0.0.0 - 239.255.255.255
-
Cluster Multicast Port
Any number between 1 and 65535 is valid.
-
Cluster Address
The Cluster Address defaults to the address:port combinations for each
server instance in the cluster.
-
In the Assign Server to Clusters dialog, associate
managed servers with a cluster.
- In the Configure Machines dialog, enter the machines you
wish to add to the domain.
- In the Assign Servers to Machines dialog, choose the which
servers to run on which available machines.
- In the Database Options and Messaging Options dialogs,
configure the domain as is appropriate to the applications that will be deployed
on your cluster.
-
In the Configure Administrative Username and Password dialog,
enter a username and password for the
administrative user for this domain.
-
In the Configure Windows Options dialog, choose whether
you want to place a link to the administration server on the Windows Start
Menu.
-
In the Build Start Menus Entries dialog, choose the
start up script used to start your cluster. (A default
start up script is automatically provided for your new domain.)
-
In the Configure Server Start Up Mode and Java SDK dialog,
select Production Mode.

In the Create WebLogic Configuration dialog, click
Create.
The WebLogic Configuration Wizard generates your domain and generates the
domain's config.xml file according to the

To Configure the Software Proxy Server
If you are using a software proxy server, you must build and configure the

To Start the Cluster
To start a cluster, you must first start the administration server and then
each of the managed servers. Do not start the managed servers until the administration
server has been started.
To start the administration server:
