Distributed adapter environments
Although it is frequently possible to install adapters
on the same computer that hosts InterChange Server Express, it is
sometimes necessary to distribute an adapter to another computer
within the enterprise network. This means installing the adapter
on a different computer than the computer on which InterChange Server
Express is installed. There are several reasons you might have to
distribute an adapter, including the following:
- Your adapter might not be supported on the same operating system
as the computer on which InterChange Server Express is installed.
For example, if your adapter is supported only on Windows, but you
are running InterChange Server Express on Linux, you will need to
distribute the adapter.
- You might improve the performance of an adapter by installing
it on a computer close in proximity on the network to the computer
that hosts the application
- You might improve the performance of the business integration
system by relieving the computer that hosts InterChange Server Express
of the load imposed by adapters
The following topics describe how a distributed adapter environment
is set up, and what to do if you want to be able to start the connector
remotely.
Setting up a distributed adapter environment
The following is an overview of the steps involved in
setting up a distributed adapter environment. Note that when you
run the Installer program, it prompts you for the choices necessary
to complete these steps. If you have already run the Installer and
made the correct choices for installing your adapter, then you have
already completed steps 1 through 4 in this list:
- Install and set up the same level of IBM WebSphere MQ as on
your InterChange Server Express machine, as described in the Installation
Guide.
- Depending on which adapter you are distributing, run either
the Installer for InterChange Server Express, or the Installer for
the Adapter Capacity Pack, on the distributed computer, selecting
for installation only the adapter that you want to distribute. Do
not select InterChange Server Express for installation on the distributed
adapter computer. See the Installation Guide for details about running
the installers. Note that in order for the adapter license to be
registered successfully, InterChange Server Express must be running
and reachable from the distributed machine.
- The Name Server Configuration Screen will appear during installation.
On the Name Server Configuration screen, type the IP address of
the computer on which you have installed the InterChange Server
Express component. See the Installation Guide for more information.
- If prompted for the InterChange Server Express password, type
the same password that you typed for the user admin when
you installed InterChange Server Express on the host machine.
- Use Connector Configurator Express to configure the connector.
- Deploy the configured connector to the InterChange Server Express
repository.
- Perform any adapter-specific installation steps, such as installing
the application client on the adapter host computer, as described
in the guide for each adapter required in the environment.
After you have installed and set up your connector, you may also
want to set up the remote restart feature; see Setting up remote restart
Setting up remote restart
The remote restart feature enables you to start and restart
connectors from System Manager. This feature uses a trigger that
is set up through the use of IBM WebSphere MQ. For information about
setting up this feature, see "Steps for setting automatic and remote
restart for a connector" in the System Administration Guide.
