Loop mechanism inside job.

[kaushal.kumar@igate.com]

Is it possible to use loop mechanism inside parallel job.
Please advice me ,in which stage i can use a for loop .

DataStage until vesion 8.1 does not support looping in pre-built stages.

This is one of the features to come in the new release.

Btw, you can write your own operator to incorporate looping.

I think sainath is not correct in saying that loop was introduced in 8.1

8.0 also had the loop stage

I assume we're talking about "looping" inside a PX job rather than a Sequence job, the latter of which goes back well before the 8.x version.

First question would have to be why - what makes you think you need to do any kind of "looping" in a job? What are you trying to accomplish?

There's a loop stage? Where do you find it? Or are you referring to the sequence loop?

[chulett]

Yes, I'm sure they are referring to the Start Loop and End Loop stages in a Sequence job.

A future version of DataStage (probably the next) will not have a Loop stage in jobs. It will have the ability to set up a looping construct within a Transformer stage - and consequently the ability for the Transformer to sent more rows to an output link than were received on its input link.
