using UCM clearcase, assuming i delivered my work from a developer stream into a view in the integration stream and no baseline created and the recomended baseline is not updated.
Assuming that in the config spec an element is selected by Latest version.
When someone new will create a child stream and view from the integration stream, what version the file will he get?
Will he get the recomended baseline file?
Will he get my file for being the "latest" version?
Thanks
He/she will get the recommended baseline, which is the default foundation baseline for a child stream.
That child stream could then be rebase with any baseline created on the parent stream, but this is not the case here.
What that child stream will not get is the "LATEST" from the parent stream. For that, you would need to create a baseline and recommend it.

I'm looking for some advice on setting up a Spring Data Flow stream for a specific use case.
My use case:
I have 2 RDBMS and I need to compare the results of queries run against each. The queries should be run roughly simultaneously. Based on the result of the comparison, I should be able to send an email through a custom email sink app which I have created.
I envision the stream diagram to look something like this (sorry for the paint):
The problem is that SDF does not, to my knowledge, allow a stream to be composed with 2 sources. It seems to me that something like this ought to be possible without pushing the limits of the framework too far. I'm looking for answers that provide a good approach to this scenario while working within the SDF framework.
I am using Kafka as a message broker and the data flow server is using mysql to persist stream information.
I have considered creating a custom Source app which polls two datasources and sends the messages on the output channel. This would eliminate my requirement of 2 sources, but it looks like it would require a significant amount of customization of the jdbc source application.
Thanks in advance.
I have not really tried this, but you should be able to use named destinations to achieve that. Take a look here: http://docs.spring.io/spring-cloud-dataflow/docs/current-SNAPSHOT/reference/htmlsingle/#spring-cloud-dataflow-stream-advanced
stream create --name jdbc1 --definition "jdbc > :dbSource"
stream create --name jdbc2 --definition "jdbc > :dbSource"
stream create --name processor --definition ":dbSource > aggregator | sink"
I am working on Clearcase/Clearquest in which I have to create the CQ's for defect for the developers. Now the defect is to be delivered in old stream and in current stream also. So for each defect I have to create 3 CQ for single developer. Say I have three stream :
8.0_dev
9.0_dev
10.0_dev
So I create same defect CQ for abouve three stream. Now problem is developer dont care to check the CQ of which stream it is . He is committing the code in 8.0_dev branch by taking CQ of 10.0_dev and it creating mess for me to create Release notes. I want to restrict the commit to the respective CQ assigned to stream. I want Clearcase gives error if CQ assigned to 8.0_dev is used for committing in any other stream, it must be used in commit in 8.0_dev and nowhereelse.
Please advise me how I implement this.
One possible lead a a preop trigger on the deliver operation (with a cleartool mktrtypr similar to the one I mentioned in "clearcase rebase permission to specific person").
In your script implementing that check (and called by the trigger), display the ClearCase environment variables which are available, and see if one would mention an UCM activity named after the CQ you created. That would mean the currently set activity is not the right one, and you can exit -1.
I created a new development stream out of an Integration stream. On the dev stream I created a dynamic view and an activity. I then added a new directory to an existing directory using clearfsimport.
e.g. cd to the parent directory where I want to add the new dir. then run:
clearfsimport -recurse -follow -nsetevent -c "adding new version" ~/newdir .
When it's all done I try to deliver the activity using clearcase project explorer. This throws an error like so:
"Merge Manager: warning: Element xxxx is not visible in view <Integration view name>
... ... ...
If this element should be visible cancel this operation, fix the prolem, and re-run the operation"
I have been doing this every week for months now and never had an issue. I'm really not sure what am I missing here or how to fix it. If it helps, the mastership of the Integration stream was transfered from a remote replica to ours. All my previous delivers were on the remote replica. But now I have complete mastership over the integration stream.
It depends on the nature of the target view (the one in which you are doing the deliver, the one associated with the integration stream): snapshot or dynamic.
You would need to check if the parent folder of xxxx is correctly checked out (or if you can check it out).
A cleartool ls in that parent folder of 'xxx' in the target (integration) view can help to test if everything seems ok.
If you are using a snapshot view, a cleartool update before the deliver can help too.
Since the integration stream mastership has just been transferred from a remote replica to your site, I would suggest the following:
1) Make sure you have created a view associated to the integration stream on your site
2) Make sure that the default delivery view is set to your integration view. You might need to reset it using the command
cleartool deliver -reset -to your-integration-view
The command above has to be launched from your development view.
I suggest you have a look at the cleartool deliver command
Is it possible to create a stream in wowza from multiple files ? So these file would be played in a row after each other? As far as I know, I can only stream from one file being in the content directory..
1.) I would like to split that one file for my own reasons, to add some security to it etc... , and then to create the playlist from these multiple files and publish it for streaming.. so it won't take that much time comparing to the second way.
2.) Or do I need to put these multiple files back together and then publish the playlist?
I would also like to consider the time of the playlist being created even using a big file. I am using ffmpeg to split the file into smaller pieces using a script.
Therefore it would be automatic, when a user would request a stream, I run the script that splits the files and creates the playlist for user..
I hope I didn't take it from the wrong way. Help please
On wowza website you can download this module to create playlists on server side without concating your files.
You may also want to check com.wowza.wms.stream.publish.Stream class which enables to you create a Stream on server side and attach playlist items to it. And this post will help you get started on how to create dynamic playlists if you need it.
Is there a command in CC to get the latest UCM activity ID through which files were delivered to Integration stream from Developer stream.
Not directly, but using cleartool lsactivity, you can list all activities of a given stream, and grep the ones with "deliver." in it, keeping the last one (the most recent one).
See more at "how to find the list activities delivered to integration stream on a particular day?": the command would be like:
cleartool lsact -in stream:aStream#\aPVob -fmt "%n\n"|grep deliver|tail
