Difference between the Sequence and Sequencer in DS?
Answer Posted / subhash
Sequence:
which allows you to specify a sequence of parallel jobs or server jobs to run. The sequence can also contain control information; for example, you can specify different courses of action to take depending on whether a job in the sequence succeeds or fails. Once you have defined a job sequence, it can be scheduled and run using the InfoSphere DataStage Director. It appears in the InfoSphere DataStage repository and in the InfoSphere DataStage Director client as a job.
Sequencer:
A sequencer allows you to synchronize the control flow of multiple activities in a job sequence. It can have multiple input triggers as well as multiple output triggers.
The sequencer operates in two modes:
ALL mode, In this mode all of the inputs to the sequencer must be TRUE for any of the sequencer outputs to fire.
ANY mode, In this mode, output triggers can be fired if any of the sequencer inputs are TRUE
