Creating the WebLogic Server cluster requires the following
tasks:
Create the members of the cluster by adding computers
(machines), configuring WebLogic Node Manager for each machine,
and creating server instances (servers) on the machine. (See, To create the members of the cluster section)
Create the cluster and add the members to the cluster. (See
Create the cluster)
To create the members of the cluster:Open the weblogic administration
console on the machine where WebLogic Administration Server is running.
In the WebLogic Server Administration Console, under Domain
Structure, click Environment > Machines.
Under Change Center, click Lock & Edit.
Click New and enter the computer name in the Name box,
select the appropriate operating system from the Machine OS list,
and then click Next.
In the Listen Address box, enter one of these values
(where the Node Manager for the machine will listen for incoming
connections):
Note: If Node Manager is
listening on a non-default port, enter the port in the Listen Port box.
click Finish.
Repeat steps 1 to 4 for each cluster node machine you want
to add to the cluster. After you add and configure Node Manager
for all the machines of the cluster, proceed to step 6.
Under Domain Structure, click Environment > Machines and,
on the Summary of Machines screen click a machine name for one of
the machines you just created.
Click the Configuration tab, click Servers,
and then click Add.
Select Create a new server and associate it with this machine and
click Next.
In the Server Name box, enter your server name (for
example, Server-0).
In the Server Listen Address box, enter one of these
locations (where the server will listen for incoming connections):
In the Server Listen Port, enter a port number for
the server, and then click Finish.
Note: Consider
the following information when deciding which port number to use:
Do not use the default value 7001 if the managed server is
on the same computer as the administration server; the default value
7001 is required by the administration server.
On a horizontal cluster, use any available port on the computer
where you are adding the WebLogic Server. Reusing the same port
numbers for additional WebLogic Server instances on other computers
of the cluster is acceptable and may simplify your cluster administration.
On a vertical cluster, use unique port numbers for each vertically
clustered WebLogic Server instance on a computer of the cluster
(for example, port number 8001 for the first instance, 9001 for
the second instance, and so on).
Repeat steps 6 to 11 for each machine hosting managed server,
and then proceed to step 13.
Under Change Center, click Activate Changes.
Create the clusterIn the WebLogic
Server Administration Console, under Domain Structure, click Environment > Clusters.
Under Change Center, click Lock & Edit.
In the Clusters table, click New and configure
these options:
In the Name box, enter your
cluster name (for example, livecycle_docsvs_cluster).
In the Messaging Mode box, select Multicast.
In the Multicast Address box, enter an IPv4 multicast
address within the range 224.0.0.0 to 239.255.255.255 (for example,
type 239.192.0.1) or, in the case of an IPv6-based
cluster, a valid IPv6 address such as ff01::1.
In the Multicast Port box, enter a port number. Valid
values are 1 to 65535. If required, you can change the default value
for this box, 7001, to some other valid value.
Note: The combination of address and port for multicasting
must be unique to the LiveCycle cluster (that is, the address and
port combination must not be used by any other cluster on the same
network)
Click OK and then click Activate Changes.
Assign servers to the clusterIn the WebLogic Server Administration Console, under Domain
Structure, click Environment > Clusters.
In the Cluster table, select the cluster you created.
See create the cluster.
Under Change Center, click Lock & Edit.
On the Configuration tab, click Servers, and
then click Add.
From the Select a server list, select the server name
to add, and then click Finish.
Note: Do
not add AdminServer to the cluster.
Repeat steps 4 to 5 for each server you want to assign to
the cluster.
Under Change Center, click Activate Changes.
