To create the cluster, you convert an existing application
server to become the first cluster member and generate additional
cluster members using the original cluster member as a template.
Before you begin
Before you begin, the following software
should be installed:
- A supported version of WebSphere® Application Server
Network Deployment
For a list of required WebSphere Application Server fixes,
refer to the readme file, WebSpheresoftwareForTelecomReadme.html,
on the QuickStart CD.
- One of the following databases for storing subscriber notification
data:
IBM® DB2® Enterprise
Server Edition
Oracle Database
- Diameter Enabler base
In addition, you should have:
- Completed the environment preparation steps
- Prepared the database
- Created an application server named diameter0
About this task
Create the first cluster member from the diameter0 application
server you have already created. Additional cluster members are added
using
Integrated Solutions Console.
- Log in to the Integrated Solutions Console:
- Open a browser and navigate to the following
URL: https://host_name:port/ibm/console.
Where:
- host_name is the fully qualified host name
of the server where the application or the network deployment manager
is deployed.
- port is the secured port used to access the
console. The default port is 9043.
Note: The default unsecured port is 9060.
If you use 9060, you must have "http" instead of "https" in the URL.
- Enter an administrator user ID and password. (Omit the password if security is
not enabled.)
- Click Log in.
- In the navigation panel, click .
- Click New.
- Type Diameter for the Cluster
name.
- Select Prefer local.
- Click Next.
- Click Create the member by converting an existing
application server, and select diameter0 from
the drop-down list.
- Click Next.
- Add additional cluster members. Repeat the following
steps for each cluster member you would like to add.
- Type cluster_member_name. For federated nodes with multiple cluster members, you will
need to know the names of each of the cluster members. Name each additional
cluster member in the convention of diameter+n, such
as diameter1 and diameter2.
- Select node_name from the Select
node drop-down list. The node_name is
the node you want the cluster to reside on.
- Select Generate unique HTTP ports.
- Click Add member to add the cluster
member.
- Click Next, and click Finish.
- Click Save to save changes to master
configuration. You should see
the following messages:
- ADMS0200I: The configuration synchronization started for cell.
- ADMS0208I: The configuration synchronization complete for cell.
- Click OK.
- Verify the HTTP transport ports are properly
defined.
- In the navigation panel, click .
- Click server_name for
the cluster member you want to verify.
- Expand Ports.
- Verify the ports listed are correct. For
vertical clusters, WebSphere Application Server automatically
increments the port numbers, including the DiameterNamedEndPoint,
to ensure they remain unique.
What to do next
You must create a proxy server and associate the proxy
server with the cluster that you have created. Refer to the WebSphere Application Server Information
Center for additional information on setting up the proxy server.
