Creating an integration node

You can create integration nodes on every platform that is supported by IBM® Integration Bus.

Before you begin

Complete the following tasks:

Ensure that your user ID has the correct authorizations to perform the task. Refer to Security requirements for administrative tasks.
On distributed systems, you must set up your command line environment before you create an integration node by running the product profile or console; refer to Setting up a command environment.
On z/OS®, you must create and start a queue manager to be specified on the integration node before you create the component.

About this task

Create an integration node by using the command line on the computer on which you installed IBM Integration Bus. Alternatively, on Windows and Linux®, you can use the IBM Integration Toolkit to complete this task.

You must give the integration node a name that is unique on the local computer. Integration node names are case-sensitive on all supported platforms except Windows.

Optionally, on all distributed systems you can specify a queue manager to be associated with the integration node. On z/OS only, specifying a queue manager is mandatory. This queue manager is used by default for WebSphere® MQ processing in the message flow if no queue manager has been specified explicitly on the MQ node. Some message flow nodes such as CD and FTE nodes, and event-driven processing nodes used for aggregation, timeout, message collections, and message sequences, require a queue manager to be specified for the integration node. These nodes use system queues, which are owned by the queue manager, to store information about in-flight messages. For information about creating the system queues, see Creating the default IBM Integration Bus queues on a WebSphere MQ queue manager.

Queues that are specified on event-driven processing nodes are created automatically when the flow is deployed, provided that the integration node has the required permissions to create the queues. If the queues are not created automatically, you can create them manually; see Creating the default IBM Integration Bus queues on a WebSphere MQ queue manager. For more information about using WebSphere MQ with IBM Integration Bus, see Installing WebSphere MQ and Enhanced flexibility in interactions with WebSphere MQ.

Multiple integration nodes can specify the same queue manager. You can also specify a queue manager to be used by an existing integration node, by using the mqsichangebroker command. You must then restart the integration node for the changes to take effect.

The mode in which your integration node is working can affect the number of integration servers and message flows that you can deploy, and the types of node that you can use. See Restrictions that apply in each operation mode.

To create an integration node, complete the steps in one of the following task topics:

If you want to configure the integration node as a WebSphere MQ trusted application, see Using WebSphere MQ trusted applications.
