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.
-
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 cluster
-
In 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,
AEM_forms_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 AEM forms 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 cluster
-
In 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
