Krishna,

A "Job Sequence", sometimes called just a Sequence, is a DataStage job type usually used to control other jobs or activities or routines. The Sequencer is a stage used in a Job Sequence which allows parallel processing streams to merge back together.

Or did you wish to ask another question

A sequencer can have 1 or many inputs and one output. The two choices are "any" or "all". "Any" means that the output is triggered when the first input link produces a row, "All" means the output is not triggered until all inputs have triggered.

4friends - that is the 3rd question in a row that is answered directly, clearly and in detail in the documentation. That is the 3rd strike for me. Perhaps someone else might wish to replace the docs for you.

Couple this question with these old chestnuts;
1. What is the acronym APT?
2. What's the difference between a transformer and routine?

and I figure somebody is ramping up for a DS Project in Chennai or Mumbai.

1. A Pre Test.....
2. the same difference as a sequential file stage and a configuration file.
