Chapter 1 General Information
This version of DCE/3000 (version A.01.12) is based on OSF DCE version
1.0.2 source code. It provides the following OSF components for the core
services:
* Remote Procedure Calls (RPC) - support the development of
distributed applications by making requests to remotely networked
machines as if they were local. RPCs also implement network
protocols used by clients and servers to communicate with each
other.
* Kernel Threads - supports the interfaces defined in Draft 4 of the
POSIX 1003.4a specification, with some exceptions as stated in
this document.
* Cell Directory Service (CDS) - manages a database of information
about the resources in a group of machines called a DCE cell. The
database consists of the names of resources and associated
attributes.
* Distributed Time Service (DTS) - provides synchronized time for
the computers in a DCE cell.
* DCE Security - provides secure communications through the use of
services such as authentication, which guarantees the identity of
users, and authorization, which keeps track of user privileges.
In the DCE/3000 version A.01.12, the DCE application library is provided
as both an archive library (libdce.a) and an executable library
(DCEXL.HPDCE.SYS). The concept of an executable library is like the
shared library on HP-UX. If you use the archive library, each application
binary will contain its own copy of the DCE routines that it calls
directly or indirectly. If you use shared library, all DCE applications
can share the single copy of the DCEXL on a system.
