propagating changes between streams - revisited

I asked this question some time ago but never really got a clear understanding of how this works. Let me try to re-phrase the question...

I have several teams, each working on different parts of a project. Each team has it's own team area containing a team stream. I'd like to create a parent stream such that each team stream is a child to this parent stream. Furthermore I'd like the changes made in the child stream to be propagated to the parent stream. Since teach team works on differnt components, there should be no merge issues in the parent stream.

Simply setting the parent stream as the flow target of the individual team streams does not seem to flow the changes from child to parent. How is this accomplished?

As a side note: The parent stream happens to be a CC synchronized stream and also the basis for daily builds.

Changes never "automatically" flow. The user (or some script or
process) needs to explicitly "deliver" (to add changes from a workspace
to a stream or another workspace) or "accept" (to add changes from a
workspace or stream into a workspace).

Defining flow targets is just a way of specifying what the default
source should be for an accept and the default target should be for a
deliver.

You should be able to use the Jazz "build" machinery to schedule the
flow to occur automatically at the interval you specify (every hour, or
whatever).

Could someone from the Build or SCM team provide details on how to drive
those deliver/accept requests from the build?

Cheers,
Geoff

In your build scripts you can call the SCM command line to deliver when a certain criteria is met, for example a green build.

Is there any information on how to use the SCM command line? I couldn't find any.

You can find a quick introduction to the SCM command line tool here:
https://jazz.net/wiki/bin/view/Main/SCMCommandLineTutorial


In addition I have two follow up questions:

1. Does anybody know where to find examples of this kind of multiple stream development? (ant build files,...)

2. Will RTC 1.0 include support to specify the stream(s) the build results need to flow to (e.g. integration streams)?

There are some example build scripts at:

$RTC_CLIENT_INSTALL\jazz\buildsystem\buildtoolkit\examples

Delivering to another stream after a successful build will be possible with 1.0. We don't have an example of doing this, but if you take one of the example build scripts, you could add a step at the end of the Ant script which would deliver using the command line client.
