Hi,
On top of what was said...
Active Stages are runtime processes, where passive stages are not.
Now you ask what happens when you do a direct link from a DB stage to a Sequential file? - under the covers a slim transformer is inserted to be the runtime process.
All part of the standard DS324 course as far as I remember.
Now one wonders what about the EE jobs? - is it the same?

Roy,
DataStage EE enables parallel processing that means executing your EE job on multiple CPUs simultaneously. Parallel server runs applications; each application has parallel connections to RDBMS. Unlike server job, each application has only one connection.

Perhaps some one missunderstood the question (is it me?!).
We were talking about passive and active stages refering to the job design some stages are concidered as passive and some active.
the question wat what is the difference between the 2 stage types not EE vrs. SE.
I ment in server jobs ds324 course says a slim transformer is inserted to produce the process.
I asked does anyone knows is it the same in PX - or what is added? or are all stages in PX are active? and so on.

The concept is (in simple words):
A stage that becomes a process when you run the job is called an active stage, the ones that don't are called pasive.
