DCE demon (dced). The process that enables complete remote administration of DCE
services and other applications, as well as their configuration parameters. This
administration includes startup, shutdown, and status queries, as well as secure
remote management of per-host security data and cell configuration information. dced
also provides a secure administration of endpoints to keep unauthorized users from
removing access to servers.
demon. On a UNIX system, a process that runs continuously to provide a specific service
for other processes. A demon does not have a controlling terminal and is not explicitly
invoked. On an HP NonStop system, a demon runs in the HP Open System Services
(OSS) environment and has an OSS process ID.
DES. See Data Encryption Standard (DES).
distributed time service (DTS). A DCE service that synchronizes time for the machines in
a DCE cell.
distributor. A DCE server with extended capabilities that allow it to distribute remote
procedure calls (RPCs) to agent processes for call execution. DCE clients cannot
distinguish distributors from standard DCE servers. See also agent.
DTS. See distributed time service (DTS).
dynamic-link library (DLL). A collection of procedures whose code and data can be
loaded and executed at any virtual memory address, with run-time resolution of links to
and from the main program and other independent libraries. The same DLL can be
used by more than one process. Each process gets its own copy of DLL static data.
Contrast with shared run-time library (SRL). See also TNS/E library.
