Yes you can run 4 jobs at a time from a sequence .In that sequence , give 4 unconnected job activities .when you run the sequence , it will run all the 4 jobs parallely

You can not run any jobs through a Sequencer.

As nagarjuna notes, you can run as many jobs as you like (given sufficient server resources) through a Sequence.

A Sequencer is a component in a Sequence that makes a decision about whether any or all of its inputs have been triggered.

Also known as a Sequence Conditioner, correct?

Often used for controlling "action(s)" following failed job activities. (Thanks to Andy for teaching me this one) :D

Never heard it called that, are you perhaps thinking of the Nested Condition stage? :?

No, that is different than what I was referring to. What I am referring to is labelled "Sequencer" in the pallette. When placed on the canvas it gets a default stage name like Sequencer_##. But, when the stage is opened, at the top of the window the title bar says Sequencer_## Sequencer Condition.

I like the longer name as it seems a little more descriptive of its purpose and reduces confusion with the aforementioned Sequence, which I think is where we started. :wink:

You had me worried though. I had to check when I first arrived at the office this morning to be sure.

Interesting... never noticed that in the stage title, and all of the documentation simply references the "Sequencer" stage. I'm guessing the "condition" may be specific to the internal setting - All or Any - but it doesn't really matter in the Grand Scheme of Things. Now we'll know what you mean when you say that. :wink:

We generally know when someone means "Sequence" (as in Job Sequence or Sequence job) when they say "Sequencer" but you'll always get a visit from Ray when you do that. Attention to detail! :D
