Use this task to create a server as a member of a server cluster.
Before you begin
Why and when to perform this task
If you want a server to take part in the distribution of workload
in a server cluster, create a cluster member for the server.
To create
a cluster member, use the administrative console to complete the following
steps:
Steps for this task
- In the navigation pane, click . This displays
the Server Cluster page, which lists the clusters in
the deployment manager cell.
- In the content pane, click the name of the cluster.
- Click Cluster members. This
displays the Cluster Members page, which lists members
of the cluster, states the nodes on which members reside, and states whether
members are started, stopped, or encountering problems.
- Click New, then follow the steps on the Create
new cluster members page.
- For Member name, type the name of a new server
to add as a member of the cluster.
- For Select node, select the node on which the
server runs.
- For Weight, specify the server
weight.
The weight value controls the amount of work directed
to the application server. If the weight value for the server is greater than
the weight values assigned to other servers in the cluster, then the server
receives a larger share of the workload. The value can range from 0 to 20.
- Make sure that Generate Unique HTTP Port is
selected.
- Under Select template:, select the defaultESBServer
template.
- Select Default application server template
- From the drop down list, select defaultESBServer.
- Click Apply to finish the cluster member. You can add
more cluster members. All cluster members you add are based on the same server
template, so there are less steps to complete.
- Click Next.
- Review the summary of information on new cluster members and
click Finish.
- Save your changes to the master configuration. As part of saving
the change to the configuration, you can select Synchronize changes
with Nodes before clicking Save on the Save
page.
- To display the properties of a cluster member, click the member's
name under Member name on the Cluster members page. This displays the settings page for the cluster member instance.
Result
You created application servers that became members of an existing
server cluster.
What to do next
You can display the properties and local topology of the cluster.
Click .
You
can change the configuration of the cluster. Note that if you have not clicked Save and
saved your administrative configuration, you only see the Configuration and Local
Topology tabs. To see the Runtime tab, you
must save your administrative configuration. Also, ensure that changes are
synchronized to the nodes as described above.
You can create
more cluster members or start the cluster. For more
information about cluster configuration options, see Balancing workloads with clusters.
You can
use scripting to automate the task of creating cluster members. For information
about using scripting for clusters, see Creating
clusters using scripting.
To manage cluster members, you can
use the Cluster
members page.. You can use this page to list the cluster members, and
to select members to display more details or to act on.
