You can use the Properties view to show and change the metadata
associated with UCM activities, baselines, branch types, elements, label types,
streams, UCM components, UCM projects, versions, views, and VOBs. Certain
types of metadata can only be changed by authorized users.
When you modify an element, version, or VOB property, you affect all users
who access that element, version, or VOB. For more information about the modifiable
and non-modifiable properties that are displayed in the Properties dialog
boxes, see Administering ClearCase® and the ClearCase Command Reference Manual.
For information about how to find these documents on line, see Team software development with ClearCase.
Permission to change a property
Modifiable properties
can be changed only by a user with adequate privileges. Your Rational ClearCase
privileges are determined by the user identity with which you log on to the ClearCase server.
If you attempt to change a property that you are not authorized to modify,
the operation fails.
Element protections
Element protections provide
a way to control access to all versions of an element by all users of the
VOB that contains the element. The protections that can be set and the meanings
of those settings depend on whether the element is a directory or a file.
- For both file and directory elements, read permission controls whether
a version of the file or directory can be loaded into a Rational ClearCase view.
- For file elements, write permission does not apply. To modify an element,
you must check it out and then create a new version by checking in your modifications.
These operations are always permitted for the owner of the element or any
member of the owning group. In addition, the user who checked out an element
is always permitted to check it in.
- Execute, set UID, and set GID permissions apply only to ClearCase dynamic
views. They have no effect in ClearCase Web views.
Descriptions
Description properties are available
for UCM activities, baselines, elements, label types, UCM projects, UCM components,
streams, versions, views, and VOBs. The text of this property is derived from
comment metadata associated with the object. If no comment was entered, no
text is displayed for the property.
- The Description property of an element shows the
element's creation comment. You can modify this comment if you are the element's
owner, the owner of the VOB that contains the element, or a Rational ClearCase administrator.
- The Description property of a checked-out version
shows the version's checkout comment. You can modify this comment if you checked
out the version.
- The Description property of a VOB shows the VOB's
creation comment. You can modify this comment if you are the VOB owner or
a Rational ClearCase administrator.
Element and VOB Locks
With the Locks tab,
available in the VOB and Element properties dialog boxes, you can lock an
element or an entire VOB. This lock prevents any ClearCase user from modifying the
element or VOB.
- You can lock an element if you are the element's owner, the owner of the
VOB that contains the element, or a Rational ClearCase administrator.
- You can lock a VOB if you are the owner of the VOB or a Rational ClearCase administrator.
Note: Locking an element or VOB by using the Obsolete attribute
locks the element or VOB and also renders it invisible to certain ClearCase operations,
none of which are supported by the ClearCase Remote Client.
