Distributed adapter environments

Although it is frequently possible to install adapters on the same computer that hosts the integration broker, it is sometimes necessary to distribute the adapters. This means installing the adapters on a different computer than the computer on which the broker is installed.

There are several reasons you might have to distribute connectors agents, including the following:

Environment 2 in Figure 1 illustrates this type of environment, where the adapter is distributed to communicate with a mainframe application.

Do the following to prepare a distributed adapter environment within the enterprise network:

  1. Obtain computers that satisfy the hardware requirements for each of the required environments.

    For more information about hardware requirements, see Hardware requirements.

  2. Install the WebSphere MQ client as described in the WebSphere MQ documentation. Be sure to install the Java Messaging feature. The supported version of the WebSphere MQ client is listed in Table 5.
  3. Do the following depending on your integration broker:
  4. Do the following to configure the environment to communicate with the broker:
    1. Open the shared environment file located in the ProductDir\bin directory in a text editor.

      On Windows computers, the shared environment file is named CWSharedEnv.bat.

      On UNIX computers, the shared environment file is named adapterEnv.sh or CWSharedEnv.sh, depending on the broker you are using and the version of its release.

    2. Set the value of the ORB_PORT property to the port over which the Object Request Broker installed on the broker computer is configured to communicate.
    3. Set the value of the ORB_HOST property to the IP address of the computer on which the broker is installed.
  5. 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.
