An event is a representation of a

document

at a particular stage of processing. The

B2B Data Exchange

server generates events as it processes

documents

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

When the

B2B Data Exchange

server receives a file that contains documents to process, it generates an event associated with the file. This initial event is a file-level event. It is the root event for the file and is the parent event for all other events that the

B2B Data Exchange

server generates during the course of processing the documents in the file. The workflow that processes the document can generate child events of the file-level event during document processing.

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. The event log provides information about the log type and a description about the event. The default description for an output message is prefixed with

Outputmessage

. To customize the output message, create a JMS target property as

outputMsgHeader

in a PowerCenter mapping.

For more information about using custom variables, see Custom Variables.

You can view parent events and child events for system events, user events, and monitor events. To track a set of events, you can create an event monitor and set up the rules for the events to be included in the monitor. You can create multiple event monitors to track events for different profiles or to track different types of events. You can configure the monitor to notify you of changes to the events that you track.

You can view all events that the

B2B Data Exchange

server generated since the last archive. To keep the volume of events displayed in the Operation Console at a manageable level, archive the events regularly. If you archive events with the

B2B Data Exchange

accelerator for Informatica Data Archive from the

B2B Data Exchange

repository to the history database, you can view the archived events in the Operation Console.
