How do I create a snapshot view of some project or stream in ClearCase?

2... 1

cleartool descr -l project:myProject@\myPVob

with some grep, you have the list of components (writable or not) and policies.

If you want only the Streams:

cleartool lsproj -tree myProject@\myPVob

You can repeat that for a Stream (to get the sub-streams)

cleartool lsstream -tree myStream@\myPVob

For the foundation baselines of a Stream:

cleartool descr -fmt "%[mod_comps]CXp" stream:myStream@\ideapvob

For the activities of a Stream:

cleartool descr -fmt "%[activities]CXp" stream:myStream@\ideapvob

If you want to consult the files (i.e. the exact version of each files) referenced by a stream, the quickest way would be to create a UCM dynamic view on that stream:

 cleartool mkview -tag myView_myStream -stream myStream@\myPVob -stg myStorage

With a dynmic view, you will not have any load rule (since it is a dynamic view).

You only need to mount the VOB which you want to see

cleartool mount \myVob

And you can start browsing the files

 M:\myView_myStream\myVob\...

For snapshot view, see "Proper ‘cleartool mkview’ for ClearCase Snapshot view creation"

 mkview -snapshot -tag myView_myStream_snap -vws \\mySharedPath\myView_myStream_snap.vws -host myHostname -hpath \\mySharedPath\myView_myStream_snap.vws -gpath \\mySharedPath\myView_myStream_snap.vws myRootDir

For the load rules, see:
