Managing Triggers

Triggers work together with time conditions for activating scheduled tasks. Users bind triggers when creating schedule tasks, and then the administrator determines whether the condition is ready and fires the triggers to start running all of the scheduled tasks waiting on the triggers at any time.

Administrators manage triggers on the JReport Administration > Trigger page (to access the page, click Triggers on the system toolbar of the JReport Administration page).

Administrators can manage the triggers in the table as follows:

• Creating a trigger
  1. Click New Trigger on the task bar of the Triggers page.
  2. In the displayed dialog, input a unique name and a description for the trigger. Click Conflict Check to check whether the name has been used.
  3. Click OK.
  4. A message box is prompted telling whether the trigger is created successfully. Click OK to close the message.

  The new trigger is now added to the trigger table and is enabled by default. The trigger table contains the following columns:

  Column	Description
  Name	Displays the names of the triggers.
  Is Enabled	Shows whether the triggers are enabled or not.
  Referenced	Shows the times when the triggers are referenced.
  Last Fired	Shows the time when the triggers are lasted fired.
  Description	Displays the descriptions of the triggers.

  You can select triggers in the trigger table by selecting the checkboxes ahead of them. To select all the triggers, check the checkbox on the column header.

• Firing triggers
  When a trigger is enabled, it can be fired to enable scheduled tasks that are bound with the trigger. To file a trigger, select it in the trigger table by checking the checkbox ahead of it, and then click Fire on the task bar. The firing time will be recorded in the Last Fired column. Multiple triggers can be fired at a time.
• Disabling triggers
  To disable the enabled triggers, select them in the trigger table and then click Disable.
• Enabling triggers
  To enable the disabled triggers, select them in the trigger table and then click Enable.
• Deleting triggers
  Triggers that have not been referred to by any scheduled tasks can be deleted. To delete a trigger, select it in the trigger table and then click Delete. Multiple triggers can be deleted at a time.
