If you need to perform Rational® ClearCase® operations in a snapshot view that you did not create or have not updated, you must register that view.
When you create a snapshot view, it is registered in the file .ccase_svreg in your home directory. When a snapshot view needs to be accessed, that file in your home directory is searched to find the path for the snapshot view root directory. If you did not create or have not updated the view that is being accessed, you must explicitly register the view.
If a snapshot view is not registered under your home directory and you try to perform Rational ClearCase operations from the snapshot view (for example, to check out a file), the view cannot be found. If you want to perform Rational ClearCase operations from this view, register the view. If you inadvertently delete or corrupt the .ccase_svreg file, you must regenerate information in it for each snapshot view that you use.
When you create or update a snapshot view or click a view shortcut in Rational ClearCase Explorer, the snapshot view is registered in your computer registry. The Rational ClearCase integration with Windows® Explorer (running in Rational ClearCase Explorer and Windows Explorer) recognizes as Rational ClearCase objects files and directories below a registered snapshot view.
If a snapshot view is not registered on your computer and you access files and directories under the view root directory through Network Neighborhood, the Rational ClearCase integration with Windows Explorer does not recognize the files or directories as Rational ClearCase objects. For example, if you use Windows Explorer to navigate to a team member's snapshot view on a different computer and right-click a file in the view, Rational ClearCase options are not available. Also, if you try to perform Rational ClearCase operations from an unregistered snapshot view, the view cannot be found.
To perform Rational ClearCase operations on the files and directories in a snapshot view that is not registered by you (for example, a team member's snapshot view), you must register the snapshot view. You can use Rational ClearCase Explorer or Windows Explorer to register the snapshot view.
