Every trigger identifies the trigger event type, which identifies when the trigger will be executed.
The trigger event types are described in the Trigger event type reference. In addition to the standard trigger event types, the ROC Plus driver makes available additional trigger event types that are used in conjunction with the ROC Plus driver trigger actions to retrieve individual records from the data files.
ROC Plus event types
The ROC Plus category is available in the Trigger Event Type list when defining or editing a trigger. This example shows a new trigger being defined with the Canvas Editor:
When a ROC Plus trigger event type is selected, the Event tab becomes active with parameters that accommodate the event type.
The trigger event variables associated with each of the event types are described in the following sections.
