Protection page

Access to elements (and all their versions) is controlled with a user/group/others permissions model. Permissions set in this page apply only to elements, shared derived objects, and other VOB objects. This permissions model is applied in the following situations:

In a snapshot view, these permissions apply only when the view interacts with the VOB. For example, these permissions apply when you update the view or when you check out files and directories.

An element is owned by a particular user (initially the user who created the object), and belongs to a particular group. To perform certain Rational ClearCase operations, such as to check out a version of an element, a user must be a member of the same group to which the element belongs.

Changing protections of an element has no effect on its checked-out versions. After you check in the element, your view typically selects the checked-in version, thus making the updated protections appear.

Permissions in the Protection page

The following permissions do not apply to files and directories loaded in a snapshot view:
Read
For Rational ClearCase, allows the element to be opened or viewed in a dynamic view, or to be loaded into a snapshot view.

For ClearCase LT, allows the element to be loaded into a snapshot view.

Write
The meaning of the write-access permission varies with the kind of object:
File elements
Write permission is not meaningful for file elements, which can be modified only by checking them out.
Directory elements
Write permission allows users to add view-private objects to directory elements in a dynamic view.
Product note: This permission does not appear in ClearCase LT.
Shared derived objects
Write access allows shared-derived objects to be overwritten with new derived objects during a target rebuild.
Execute
Allows an element in a dynamic view to be executed by an application.
Product note: This permission does not appear in Rational ClearCase LT.
Set UID
Sets the element set-UID bit, which is part of file systems on the UNIX system. Applicable only when the element is accessed from a file system on the UNIX system.
Set GID
Sets the element set-GID bit, which is part of file systems on the UNIX system. Applicable only when the element is accessed from a file system on the UNIX system.
