UID A nonnegative integer that uniquely identifies a user within a node.
The UID is a scalar number consisting of the group number multiplied by 256 and added to the
member number; for example, the UID of the super ID is (255*256) + 255, or 65535. The UID
is used in the OSS environment for functions normally associated with a UNIX user ID.
See also user ID.
Unbounded open
resource
An OSS file-system resource that is used to control the number of OSS opens or operations on
OSS opens. An unbounded resource is restricted only by memory pool limits and the ALL OPENS
bounded resource. For more information about unbounded resources, see “OSS File System
Resources Overview” (page 94).
See also Bounded open resource.
unmount To make a fileset inaccessible to the users of a node.
user ID The unique identification of a user within a node.
In the Guardian environment, the term “user ID” usually means the group number and member
number pair; for example, the user ID of the super ID is usually described as (255, 255). In the
OSS environment, the term “user ID” usually refers to the single number that is the scalar view of
the user ID—a number called the UID.
See also UID.
UTC See Coordinated Universal Time (UTC).
working directory A directory, associated with a process, that is used in pathname resolution for pathnames that
do not begin with a slash (/) character.
