About HP-UX DCE Version 1.9

HP-UX DCE Core Services Software

HP-UX DCE server Version 1.9 (see “Product Bundle Numbers” on page 8 for product number information) is

based on OSF DCE Version 1.2.1 source code, with bug ﬁxes and value-added functionality. HP-UX DCE

Client comes with HP-UX core. This section describes the contents of this release of HP-UX DCE Server

version 1.9.

High-Level Features of HP-UX DCE 1.9

Following are the high-level features of HP-UX DCE 1.9:

• Remote Procedure Call (RPC) Facility, supporting both connection-oriented (TCP/IP) and connectionless

(UDP/IP) transport protocols.

• CDS, including CDS server replication.

• Access to the CDS name space through the X/Open Directory Service (XDS) and X/Open Object

Management (XOM) services. The OSF DCE 1.0.3 versions of the XDS, XOM, and dual libraries are a

part of libdcekt, and the necessary XDS and XOM header ﬁles are provided.

• Security Service, including security server replication and additional security server replication

functionality, and the Audit Service.

• Distributed Time Service (DTS); this release supports ntp, null, and Spectracom DTS time providers; it

also supports global time servers and DCE time zones.

• Global Directory Agent (GDA), using the Berkeley Internet Naming Daemon (BIND).

The DCE application library is provided as a shared library (libdce.sl). If you use the shared library, a DCE

application can share a single copy of the library with other DCE applications that are running on the same

host.

Hewlett-Packard strongly recommends the use of shared libraries when building DCE applications. The

advantages of shared libraries — smaller executable size, reduced memory requirement, and the ability to

make use of forthcoming improvements to libdcekt without rebuilding or relinking binaries — outweigh the

modest performance penalty HP has measured when testing a high-volume transaction processing

application linked with DCE shared libraries.

Supported Features in HP-UX DCE 1.9

HP-UX DCE 1.9 supports the following features that were added in previous releases of HP-UX DCE:

• The HP-UX DCE Account Manager provides a graphical interface for creating and administering the

DCE registry. The Account Manager requires a bit-mapped display. There is no ASCII terminal support.

Online help is provided for the Account Manager. See“HP-UX DCE Account Manager” on page 18 for

more information on the Account Manager.

• DCM, the DCE Conﬁguration Manager (HP-UX DCE 1.4 and later releases) allows you to conﬁgure the

nodes in a DCE cell. This tool is accessible via SAM (the HP-UX System Administration Manager) and is

documented in online help.

• A set of HP-UX Integrated login utilities that authenticate users via the DCE Security Registry instead of

via /etc/passwd and /etc/group. HP-UX DCE 1.9 includes improvements to login, dtlogin, su,

passwd, telnet, and rlogin, as well as new HP-UX Integrated versions of ftpd and dtsession and

enhanced support for CDE/PAM. See Chapter 6, “Conﬁguring HP-UX DCE Cells,” on page 47 for more

information about these utilities.
