Large Messaging sample

The Large Messaging sample is a message flow sample application based on the scenario of end-of-day processing of sales data.  Messages representing sales though the day are batched together in the store for transmission to the IT center.  On receipt at the IT center the batched messages are split back out into their constituent parts for subsequent processing. 

This splitting is achieved using an IBM Integration Bus message flow.  Each of the individual messages representing a sale has the same structure. 

The Large Messaging sample demonstrates how to:

• Process messages that contain repeating structures.  This includes processing the iterations of the repeating structure individually.
• Minimize the virtual memory requirements for the message flow.  This technique can be useful in many situations but it is particularly useful when processing messages that are many megabytes in size.

The messages used in the sample are self-defining XML.  This is used for simplicity.  Other message formats could easily be used.

NOTE: In WebSphere Message Broker Version 8.0 and IBM Integration Bus, message model schema files contained in libraries are the preferred way to model messages for most data formats, including the new DFDL domain. Message sets continue to be supported, and are required if you use the MRM or IDOC domains. You can continue to import and deploy message sets for use in message flows. However, if you need to create one or more message sets, message definitions, or message categories when using this sample, you must first enable message set development in the IBM Integration Toolkit. For more information, see Enabling message set development in the IBM Integration Bus documentation.

Read about the sample

You can set up the sample in one of the following ways:

• Import and deploy the sample

  This option imports the sample files into your workspace and deploys the sample to the integration node. This option also sets up additional resources for the sample, for example, WebSphere MQ queues.

• Import the sample

  This option imports the sample files into your workspace. Additional manual steps might be required to configure the sample for testing.

You can import or import and deploy a sample only when you use the information center that is integrated with the IBM Integration Toolkit.

Extend the sample

When you have finished with the sample, you can remove it in one of the following ways:

• Remove the sample from the integration node, but leave its resources in the workspace
• Remove the sample from the integration node and the workspace
