About element, version, and VOB properties

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.

Permission to change a property

Modifiable properties can be changed only by a user with adequate privileges. Your DevOps Code 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 DevOps Code ClearCase Web 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 on UNIX and Linux systems.

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 DevOps Code 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 DevOps Code 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 DevOps Code ClearCase administrator.
  • You can lock a VOB if you are the owner of the VOB or a DevOps Code 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.
