Triggers in the Transformer stage of DataStage
Use the Triggers tab to choose routines to be run at specific execution points as the Transformer stage runs in a job.
You can choose routines to be run at specific execution points as the Transformer stage runs in a job. The execution point is per-instance, that is, if a job has two transformer stage instances that are running in parallel, the routine is called twice, once for each instance.
The available execution points are Before-stage and After-stage. The available built-in routines are SetCustomSummaryInfo, which collects reporting information, and SetUserStatus, which sets an internal value for user status.
You can also define custom routines to be executed. To define a custom routine, you define a C function, make it available in UNIX shared library, and then define a parallel routine.
