1 General Information
This version of DCE/3000 (version A.01.02) 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.
