Configuring multi-instance integration nodes

Use WebSphere® MQ to configure an integration node to run in multi-instance mode for high availability.

Before you begin

  • Review the topic Multi-instance queue managers in the WebSphere MQ product documentation to understand the use of multi-instance queue managers.

About this task

The set of tasks that describe how to configure a multi-instance integration node assumes the following criteria:
  • A file server is configured to host both the shared work path directory for the multi-instance integration node and the shared directories for the multi-instance queue manager.
  • The file server is shared between two computers, each of which has a licensed copy of the IBM® Integration Bus and WebSphere MQ products installed.

The steps apply to all operating systems that are supported by IBM Integration Bus and WebSphere MQ, except for z/OS®. Multi-instance integration nodes and multi-instance queue managers are not supported on z/OS.

To configure an integration node to run in multi-instance mode, complete the following steps.

Procedure

  1. Create a shared path directory on an NFS or NAS server.
    On Windows, you can use a shared UNC path. Follow the steps as described in the WebSphere MQ product documentation; see Creating a shared file system.
  2. Create or configure the multi-instance queue manager. Follow the appropriate steps for your operating system as described in the WebSphere MQ product documentation; see Create a multi-instance queue manager.
  3. Follow the steps to create the multi-instance integration node as described in Creating a multi-instance integration node.

What to do next

After you have created a multi-instance integration node, you can also optionally complete the following actions.
