DCE/3000 Components and Files
Domestic and International Version
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) — supports 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.
