Stream connected to an another stream
Hello,
I am a beginner on the JAZZ RTC and I have a question about the stream usage. I want to create stream connected to an another stream For example: Stream2 | |-------------------------- Stream3 Stream1 | 2 teams develop different component and have both one main collaboration stream stream1 and stream2. And when a change set is delivered to the stream 1 or the stream 2, I want to have the change set propagated to the Stream3 I tried several combinations but I didnt received any incoming change in the stream3. What is the meaning on an arrow between 2 streams?? Thanks for your help. |

For an example of changes flowing from Stream to Stream take a look at: http://jazz.net/library/article/40
At the end there is a flow diagram example from one of the development teams on jazz.net. The pieces that are not being show are the workspaces that are connecting the two streams, reading through the article helps explain the concepts of flowing changes between them, if you have other questions after that post away. -Sean |

When you make a stream a flow target of another stream, that is just a
comment to let other users know what your intent is for those streams. To flow changes from one stream to another, you need to create a workspace, where you would accept changes from the one stream and deliver those changes to the other stream.

You can also flow these streams automatically without using a workspace by leveraging the build engine. I have done it but try to avoid it for a variety of reasons. If you do want to do it - I believe there is an article now posted by Rational describing how to do it.

The only technique I am aware of for directly updating a target stream
from a source stream without using a workspace would be to create a baseline in the source stream and then to update the component in the target stream to select that baseline. This has the risk of overwriting changes in the target stream, so isn't an approach that I'd recommend, unless this is the only process that ever updates that component in the target stream. If there is some other technique, I'd be very interested in hearing about it. Cheers, Geoff On 1/28/2011 1:38 AM, rpelliottjr wrote: You can also flow these streams automatically without using a |

You can use the scm client abilities to copy from stream to stream by leveraging the build engine. I did it by simply creating a batch file.
The Rational article provides an ant script in xml showing this approach. http://jazz.net/library/article/529 (Delivering Change Sets Automatically Between Streams) The only technique I am aware of for directly updating a target stream |

Interesting ... the documentation on the "scm deliver" command states:
"Deliver change sets from a repository workspace to another workspace or stream". I'll submit a work item to fix the documentation. So apparently, although you cannot deliver directly from one stream to another via the GUI, you can deliver directly from one stream to another via the scm command line. As a side note: the article is titled "Cool Hidden Features in Rational Team Concert : Part 2" ... given the documentation, this is correctly classified as a hidden feature (:-).

Just curious, do you need that delivery to be conditional (e.g. after a build in stream 1 or 2 is successful) or not? If stream 1 and stream 2 are not identical, is it possible the change sets can't always be delivered to stream 3 (or maybe the change sets from stream 1 come from component 1 and those from stream 2 come from component 2)? Thanks, Christophe Cornu RTC SCM Client |

I have used the scm command tool, to deliver change set from one stream to another stream and it works. Best Regards, Denis |
