问题
Can I create a snapshot view with an old baseline without creating a new stream from the source stream? I have been creating a child stream and pointing it to the old baseline; then making a snapshot of the newly created stream with the old baseline. Not really a big deal just curious if there is another way
回答1:
If the baseline is a full baseline, then yes, you can create a base snapshot view with a config spec like:
element * CHECKEDOUT
element /Vob/Component/... YourBaselineId
element * /main/0
See "What is the difference between Full baseline and Incremental baseline in Clearcase UCM?" to know more about the importance of using a full baseline for base ClearCase views.
Otherwise, your method (sub-stream, rebase, mkview) is the standard one, creating an UCM view based on the configuration of the sub-stream.
