RPC: An exception condition, occurring on a server, that is transmitted to a client.
DFS: The part of a file server machine's kernel that responds to file or directory information requests from the client's cache manager.
file server machine
DFS: A system that maintains one or more local file systems on disk and makes them available (exports them) to other nodes through the file exporter. See also server machine.
DFS: A mountable subtree of the directory hierarchy.
DFS: A hierarchical grouping of files managed as a single unit. DCE LFS supports multiple filesets within a single aggregate; in other file systems used with DFS, filesets are equivalent in size to a partition.
fileset database machine
DFS: A server machine in a cell that houses the FLDB. See also server machine.
DFS: In the DFS backup system, a collection of one or more fileset entries. It defines a group of filesets to be backed up together (at the same time and in the same manner).
fileset family entry
DFS: A single definition in a DFS backup system fileset family. It defines a collection of filesets in terms of their common site, their prefix, or both. See also site.
DFS: Part of the data structure that records information about a fileset. The fileset header records status information such as the current size of the fileset, the quota of the fileset, and the ID number of the fileset. Information such as the fileset ID is also stored in the entry for the fileset in the FLDB.
fileset ID number
DFS: A number that uniquely identifies each fileset. The read/write and backup versions of a fileset each have their own fileset ID; all copies of the read-only version share the same fileset ID.
DFS: A file containing information about a fileset, such as its name, fileset ID, unique identifier, type, and status.
fileset location database (FLDB)
DFS: A database that records the location and other status information about available DCE LFS and non-LFS filesets, allowing transparent data access. To be available, a fileset must be exported, registered in the FLDB, and mounted in DFS. The FLDB is maintained by the FL server.
fileset location server (FL server)
DFS: A server process that runs on fileset database machines and maintains the FLDB, which tracks the locations of all DCE LFS and non-LFS filesets.
DFS: The part of the cache manager that maintains a list of accessed filesets, their mounted positions in the global file system tree, and their physical locations.
DFS: A name that uniquely identifies each fileset. All versions of a fileset have the same name; the read-only and backup versions have .read-only and .backup extensions.
DFS: A disk space limit that a system administrator imposes on each read/write fileset.
DFS: The part of the file exporter that stores information about filesets residing on the local machine.
DFS: A server process that runs on all file server machines. It provides the interface for system administrators to perform all tasks that treat a fileset as a unit, including creating, deleting, backing up, cloning, and moving.
DFS: The global file system made available to all cells in DCE by DFS. Every entry for a file or directory in DFS resides in the DFS filespace. See also Distributed File Service, DCE.
An assertion about the presence or value of certain attributes of an entry in order to limit the scope of a search.
Specifies the conditions that must be satisfied before audit records are written, and where to write these records: the audit trail file or the console.
The prescribed procedure used to resolve overlapping directives from different filters.
Denotes the principal, group, or cell to which the filter applies. The filter subject is the client of the distributed application program that caused the event to occur. A filter is always associated with one and only one filter subject.
GDS: A DSA that holds the master entry of a first-level object. See also first-level object.
GDS: A directory object that is an immediate subordinate to the root.
See fileset location database.
DFS: To force the cache manager to discard data from the local cache, so that the next time an application requests the data, the data must be fetched from the file exporter.
A cell other than the one to which the local machine belongs. See also local cell.
foreign cell surrogate
Principals (whose names are in the form krbtgt/cell name) that are maintained in the registry database for the purpose of intercell authentication. To accomplish intercell authentication, the foreign cell surrogates in each cell's registry share a secret key. This secret key is known to both the local and foreign cell's Authentication Service. It is through their surrogates that two instances of the Authentication Service are able to convey information about their respective principals to one another, thus enabling a principal from one cell to acquire a ticket to a principal in another cell. See also trust peer.
DFS: A dump set in the DFS Backup System that includes all of the data from a fileset. A full dump is different from an incremental dump. See also dump, incremental dump.
CDS: The complete specification of a CDS name, including all parent directories in the path from the cell root to the entry being named.
RPC: A pointer without the restrictions of a reference pointer.
DFS: In the DFS backup system, a full restore returns a fileset to its state when last dumped. The resultant fileset includes data from the last full dump and all subsequent incremental dumps, if any. A full restore is different from a date- specific restore. See also date-specific restore, restore.
fully bound binding handle
RPC: A server binding handle that contains a complete server address including an endpoint. See also partially bound binding handle .
A programming language construct, modeled after the mathematical concept. A function encapsulates some behavior. It is given some arguments as input, performs some processing, and returns some results. Also known as procedures, subprograms or subroutines. See also operation.
