| This question is regarding WMB User-Defined Patterns. Is anyone aware of a capability to generate a pattern instance programatically? The goal is to avoid manually going to the toolkit and clicking the 'generate' button. |

The pattern is defining my desired model data flow. I don't mind answering a few config questions and clicking the generate button once or twice. In my scenario, I would need to do this 100+ times (continues to grow). Then I will need to come back and enhance the pattern and apply the enhancement to 100+ instances.
The question is not unreasonable. Manually clicking the generate button kicks off a process that reads parameters and creates a single instance. I just want to call that process, passing it the parameters, and have it generate the same single instance. I'll just call it 100+ times.
Esa - You might find the concept of "interest", well, interesting. |

I wish I had as many messages as you have flows... America must be a wonderland.
Sorry about the remark. I just couldn't resist and it slipped before I saw that a lot of people are making money out of nothing already. It's just no my thing. Interest, tax evasion or financial derivatives, you name it.
Patterns are a way to develop standardized, productive tools to integration architects, that's how I see it. A bit narrow view, I must admit.
If you need to generate hundreds of instances of a pattern, instantiating them is slow and an overkill. Whi dont you just copy the first instance in the filesystem and modify the copies. It's mostly XML, you know.
And seeing mqjeffs comment after previewing my reply: in Berlin they said that in V8 you can write flows without the toolkit with Message Broker API. You don't need to instantiate patterns. I wasn't sure if I remembered this correcly, so I did not mention it. But I think mqjeff just did. |

If my pattern / design / scenario required me to have 100 almost identical flows (because they can be generated with the same pattern with a few config changes they must be nearly identical) then I'd review my design!

I understand, it happens.

It is an interesting idea. I've actually done that and was looking for something a bit less 1-off. I can't help but feel I am hacking up a fragile solution when doing this. Then if a enahnce the pattern, do I have to re-engineer my hack? I was hoping the pattern would standardize an approach to this.

I guess I will be doing some v8 specific research. Thank you for the suggestion. |

For the purposes of pattern generation, you can use the Flow API in V7.0.0.2 as well. It's meant for precisely this purpose.
Don't hand-crank the .CMF XML; it's prone to failure and unsupported by IBM. |

But can you skip the pattern step in V8, that's the question for which your answer is still a bit unclear... |

True, thanks! If you have a need for points of variability and an easy distribution mechanism, then use the Patterns framework - either V7 or V8.
For purely algorithmic flow creation/editing, then use the V8 Flow API standalone. |

In looking at 7.0.0.2, I see a PatternInstanceManager is passed. I am able to work with it, modify the single pattern instance, and have it generate a single pattern instance in the toolkit under the pattern instance project.
Further, I can modifiy and write multiple unique flows to the file system all under a newly created directory, each flow with its own configuration, using the renderer.
Does anyone have any suggestions as to how to programatically have the multiple generated flows created and recognized under the pattern instance project?  |
