Access UCM with a base ClearCase view

Sometimes, it maybe desirable to use a base ClearCase view to access a UCM baseline. This may happen when the code is read-only and you want to save the effort of joining the project and managing the streams, such as for build purpose.

The config spec looks like the following.

element /vobs/MyVob /main/0 –nocheckout
element * baseline_07_13_2007 –nocheckout

The first line is there for retrieving the vob root, because the vob root will not get labeled when creating the baseline.

Mmmm... The two lines should be flipped (at least in a multi-component VOB). Otherwise, /main/0 version of all subdirectories are selected and they contain no data.

Now, I am confused as to how /main/0 of the VOB root can have some contents... When adding directories to VOB root, you must checkout the root, add the directories, then check back in, making /main/1 (or greater). Is the VOB root special such that /main/0 always selects all directories underneath?

Okay, I see now. In a Multi-component VOB, all components are cataloged within the /main/0 version of the VOB. This way the baselines need only to be applied to the component root.
