ClearCase: How do I know the parent branch of a br

问题:

Is that possible to get hierarchy of branches? I have to know the father of a given branch I have to know the children of a given branch

How do I get it by cleartool? I prefer not to be based on a view config-spec

Thank you!

With base ClearCase, you cannot know the parent of a branch, because it can vary from file to file: a file can start branch 'B2' from '/main/LATEST', another can start the same branch from '/main/B1/LATEST'.

For ClearCase UCM, you can determine the parent of a branch by querying the ancestors of a Stream (since the branch is name after the stream):

cleartool lsstream -anc myStream@pvob

That is possible because branches are linked to Streams, which are organized following a strict hierarchy a Parent Stream / Children Streams.

Note that describing a stream (cleartool describe, using fmt_ccase) only gives you access to the children streams: hence the lsstream -ancestor, in order to display its parent.
