LAN

See Local Area Network.

leaf entry

A directory entry that has no subordinates. It can be an alias entry or an object entry.

leap seconds

An infrequent adjustment to UTC to account for the irregularity of the earth's rotation.

LFS, DCE

See Local File System, DCE.

little endian

An attribute of data representation that reflects how multioctet data is stored in memory. In little endian representation, the lowest addressed octet of a multioctet data item is the least significant. See also big endian.

load balancing

DFS: Distributing system load evenly across File Server machines by placing frequently accessed DCE LFS filesets among available File Server machines.

local application thread

RPC: An application thread that executes within the confines of one address space on a local system and passes control exclusively among local code segments. See also application thread, RPC thread, client application thread, server application thread.

Local Area Network (LAN)

A set of computers sharing a network that does not include bridges or WAN links.

local audit trail file

The audit trail file that is specified by the user, using any convenient path name. This is specified when the audit daemon is started. If the file name is not an absolute path name, the file is created in the <dcelocal>/var/audit/adm directory.

local cell

The cell to which the local machine belongs. See also foreign cell.

local DSA

GDS: A DSA that is resident on the same computer as the DUA.

Local File System, DCE (DCE LFS)

DFS: The high-performance, log-based file system provided by DCE. DCE LFS supports multiple filesets within a single aggregate, fileset replication, fast system restarts, and DCE ACLs.

local name

A name that is meaningful and usable only from within the cell where the entry exists. The local name is a shortened form of a global name. Local names begin with the prefix /.: (or the prefix /: for names in the DFS filespace) and do not contain a cell name.

local server

DTS: A server that synchronizes with its peers and provides its clock value to other servers and clerks on the same LAN.

local set

DTS: All of the servers in a particular LAN.

local type

RPC: A type named in a [represent as] clause and used by application code to manipulate data that is passed in a remote procedure call as a network type. See also network type.

lock token

DFS: A token that allows a client to place a lock on a range of bytes in a file. Read and write lock tokens are available.

log

DFS: A record of the actions of a program or system and any changes to data associated with those actions. DCE LFS also maintains a log of changes to metadata on each LFS aggregate.

log-based file system

DFS: A file system in which changes to metadata are recorded in a log associated with the aggregate on which that file system is located. DCE LFS is a log-based file system. See also log.

Login Facility

A DCE Security facility that enables a principal to establish its identity and assume other identities.

low convergence

A setting that controls the degree to which CDS attempts to keep all replicas of a directory consistent. Low convergence means CDS does not immediately propagate an update; it simply waits for the next skulk to distribute all updates that occurred since the last skulk. Skulks occur at least once every 24 hours on directories with low convergence. Low convergence helps conserve resources by avoiding update propagations between skulks. To control convergence, you set a directory's CDS_Convergence attribute. See also high convergence , medium convergence.
