Telecom Web Services Server makes
use of the horizontal and vertical clustering capabilities that are
offered with WebSphere® Application Server.
Using various clustering techniques, you can achieve a high-availability
system.
Before installing the
Telecom Web Services Server product,
you must create one or more clusters. There are a variety of ways
in which to do this:
- You can create a single cluster for all of the Telecom Web Services Server components.
- You can create two or more clusters: for example, a cluster for
the Access Gateway and
another cluster for the nodes where you will deploy the Service Platform components and Web service implementations.
(The topic Standard configurations for Telecom Web Services
Server illustrates a typical setup with two clusters.)
- You can set up a single deployment manager, with unique clusters
for each of the components but sharing the same nodes.
This information center provides instructions for setting up the
following typical configuration:
- One database server
- One cluster for the Access Gateway
- One cluster for the Service Policy Manager
- One cluster for Service Platform components and Web service implementations
You must create an HTTP proxy server (and optionally a SIP proxy
server) and associate the proxy server or servers with
each cluster that you create. Refer to the WebSphere Application Server information
center for additional information about setting up the proxy server.
