Business event processing

Use this information to understand business event processing for the z/TPF system.

What is business event processing?
A business event is anything that happens that is significant to a system. Business event processing is the capture, enrichment, formatting and emission of events, the subsequent routing and any further processing of emitted events (sometimes in combination with other events), and the consumption of the processed events.
How business event processing can help your business
You can use business event processing to enhance governance for standards compliance, and to monitor business processing. Business event processing enables detection of business situations, providing early and intelligent insight to assist you in making timely and effective business decisions.
z/TPF and business event processing
You can specify, capture, and transmit business events from the z/TPF system. When a specified event occurs, the z/TPF system collects the data, and then formats and transmits the data to the event consumer through one or more dispatch adapters.
Plan for business event processing
There are several aspects to consider when you use business event processing.
Configuring and enabling business event processing
Before you can use business events, you must configure and enable business event processing on the z/TPF system.
Increasing the size of the IBEVCNTL format-2 global record
You can increase the size of the IBEVCNTL format-2 global record to hold unordered user-defined dispatch queues that exceed the current limit.
Defining and deploying business events
Before the z/TPF system can generate and process business events, you must define and deploy event message business event artifacts to the z/TPF system.
Removing a loosely coupled processor
When you remove a processor that uses business event processing from a loosely coupled complex, you must move the business event dispatch queue on that processor to another active processor.
Business event deployment descriptors
Business event deployment descriptors are specialized XML files that contain the characteristics for each business event. These XML files must be deployed on the z/TPF system before they can be used.
Event message
The event message format is used to describe business events that are created by the z/TPF system. The event message format for a business event is defined by the DFDL schema file specified by the <esEventMessageFormat> element in the business event specification.
Enrichment programs
An enrichment program is an optional user-written program. You can use an enrichment program to modify event controls specified in the business event specification and to gather additional information about the business event that you want to pass along to the event consumer.
Business event format
You can format the business event based on a standard format or a custom format. The format is specified in the business event dispatch adapter specification.
Dispatch adapters
A business event dispatch adapter is a transport mechanism that sends the formatted business event from the z/TPF system to the event consumer.
