BusinessObjects Enterprise EventsLesson OverviewThis lesson provides information on the Event Server.In this lesson you will learn about: understanding events in the BusinessObjects Enterprise using the Event Server configuring the Event ServerIntroductionThe purpose of this unit is to describe event-based scheduling and BusinessObjects Enterprise events.After completing this unit, you will be able to: describe event-based scheduling describe BusinessObjects Enterprise eventsEvent Based SchedulingEvent-based scheduling provides you with additional control over setting schedules for reports. You can set up events so that reports are processed only after a specified event occurs. Working with events consists of two steps: creating an event scheduling a report with eventsOnce you create an event, you can select it as a dependency when you set a schedule for a report. The schedule runs only when the event occurs. Events are created in the Events Management area of the Central Management Console.BusinessObjects Enterprise EventsYou can create three kinds of events: File eventsFile-based events are monitored by the Event Server. When you define a file-based event, you specify a filename that the Event Server should monitor for a particular file. When the file appears, the Event Server triggers the event. The Central Management Server (CMS) then runs any schedule that is dependent on the event.If the file already exists prior to the creation of the event, the event is not triggered. In this case, the event is triggered only when the file is removed and then re-created. If you want an event to be triggered multiple times, you must remove and recreate the file each time. Schedule eventsWhen you define a schedule-based event, you select a report whose existing recurrences schedule serves as the trigger for your event. In this way, schedule-based events allow you to set up contingencies or conditions between scheduled reports and determine the order in which they will be run.Schedule-based events are dependent upon scheduled reports. That is, a schedule-based event is triggered when a particular scheduled report has been processed. When you create this type of event, it can be based on the success or failure of a scheduled report, or it can be based simply on the completion of the job. Schedule events are monitored by the CMS. Custom eventsWhen you create a custom event, you create a shortcut for triggering an event programatically.A custom event occurs when a programmatic method is called. You can explicitly click Trigger this event in the Central Management Console to simulate a programmatic trigger. Custom events enable you to trigger events through a custom application outside of BusinessObjects Enterprise.As with all other events, a report based on a custom event runs only when the event is triggered within the time frame established by the reports schedule parameters. Custom events are useful because they allow you to set up a shortcut that, when clicked, triggers any dependent schedule requests. Custom events are monitored by the CMS翻译：Using the Event ServerIntroductionThe purpose of this unit is to describe the responsibilities of the Event Server.After completing this unit, you will be able to: describe the responsibilities of the Event ServerThe Responsibilities of the Event ServerWhen you set up a file-based event within BusinessObjects Enterprise, the Event Server monitors the directory that you specified. When the appropriate file appears in the monitored directory, the Event Server triggers your file-based event. The Event Server notifies the CMS that the file-based event has occurred. The CMS then starts any jobs that are dependent upon your file-based event.After notifying the CMS of the event, the Event Server continues to monitor the directory for the appropriate file. In order to reset the event, the file must be removed from the directory, and the Event Server must register that the file has been removed. When the file is newly-created in the monitored directory, theEvent Server again triggers your file-based event.翻译：Configuring the Event ServerIntroductionThe purpose of this unit is to describe how to configure the Event Server.After completing this unit, you will be able to: set the File Polling interval identify auditing options for the Event ServerSetting the File Polling IntervalThe Event Server is responsible for monitoring files to trigger file- based events. The only configuration setting for the Event Server is the file polling time, which can be set in the Central Management Console and the Central Configuration Manager.The Properties tab of the Event Server in the Central Management Console allows you to change the frequency with which the Event Server checks for file events. This File Polling Interval setting determines the number of seconds that the server waits between polls. The minimum value is oneTo modify the polling time1.Go to the Servers area of the CMC.2.Click the link to the Event Server whose settings you want to change.3.Make your changes on the Properties tab.The value that you type must be one or greater4. Click Update.5. Return to the Servers area of the CMC and restart the server. Auditing Options for the Event ServerYou can configure the Event Server to audit these actions: an event is registered an event is unregistered an event is updated an event is triggeredActivity: Scheduling Reports with EventsObjectivesIn this activity, you will first create
