Is it possible to open a view (snapshot or dynamic, maybe readonly) on any given baseline (recommended or older) in a stream (integration, development or child) for performing some tasks and then remove the view when done? How?
To open a view to a given baseline, you actually need a view associated to a stream with said baseline as a foundation baseline.
That means you need to rebase that stream first, which is:
- not always desirable (since you would need to merge said baseline with current content, and that doesn't always make sense)
- not always possible (you can only rebase a sub-stream with baselines coming from its immediate parent).
What is possible is to:
- get the stream on which your baseline has been put
- make a sub-stream from that stream, taking said baseline as the foundatio one
- create a snapshot or dynamic view on it
- do your work
- put a new baseline, and deliver it to its parent stream
- obsolete that sub-stream (and you can delete your view if you want)
Note: you could create a base ClearCase dynamic view (ie non-UCM) with a config spec you could then change as you want, but that wouldn't allow you to checkout and modify any file.
That would only be a convenient way to visualize any baseline of your choice.
