An event is a representation of a

publication or a subscription instance,

at a particular stage of processing. The

Data Integration Hub

server generates events as it processes

publications and subscriptions

, and it changes the status of the events as they go through the transformation process.

When an application triggers a publication, if the triggered publication has a pre-process, the publication event also tracks the pre-process. When a subscription triggers a post-process, the subscription event also tracks the post-process.

When an application that runs a publication pre-process publishes data or files to the publication repository, the

Data Integration Hub

server assigns an event to the publication as follows:

If a file publication publishes more than one file,

Data Integration Hub

creates a File event for each file that it picks up.

Data Integration Hub

creates a Publication event after all the files are picked up.

The Publication event is the root event and the parent event for all of the subscription events that the

Data Integration Hub

server generates during processing. After the published data is ready for subscribers, the

Data Integration Hub

server generates a Subscription child event for each subscriber that needs to consume the published data. The Publication event contains aggregated status information for all Subscription child events.

You monitor and perform actions on events in the Operation Console. You can view all events on the Event List page. You can perform a basic or advanced search for events, and drill down to a specific event to view event details.

By default, the Event List page displays root events: Publication, File, Aggregated Subscription, and Compound Subscription. After a publication is ready for subscribers, you can drill down to the associated Subscription child events of the publication.

You can

create rules that monitor publication and subscription events, and perform actions on events that are in a defined status.

For example, you can create rules to perform the following tasks:
