This page is available if the object is in a replicated VOB. The page displays Rational® ClearCase MultiSite® mastership information about the selected object, including the current replica and the master replica of the object. The mastership of an object determines who can modify it. In general, if your current replica does not master an object, you cannot modify it.
The Request for mastership section of the tab is displayed only if the replica is your current replica.
The Request for mastership section displays the settings for mastership requests for the branch or branch type.
Show Request Mastership Controls retrieves information from the master replica of the branch or branch type. If your current replica is the master replica, the button is not available.
Mastership for a label type, attribute type, or hyperlink type can be shared or unshared. You can create instances of an unshared type only if your current replica masters the type. You can create an instance of a shared type only if your current replica masters the object to which you are attaching the instance. This restriction prevents conflicting changes from being made at different replicas. If a type is shared and global, you cannot create instances of the type unless the client VOB contains a local copy of the type, or the administrative VOB at the current site masters the type.
You can change an unshared type to shared, but you cannot change a shared type to unshared.
