For 10.20 and 10.10: For 10.20,
HP DCE/9000 Version 1.5 client software is included in
default HP-UX system software bundles.
For 10.10,
HP DCE/9000 Version 1.4.1 client software is included in
default HP-UX system software bundles. The functionality ensures
that any HP-UX 10.20 and 10.10 system that has installed the default system
software bundles can be configured as a DCE client, and as such,
will operate with HP/DCE 9000 servers or with DCE servers from
another vendor and can run any DCE RPC application. Also bundled with HP-UX 10.20 and 10.10 is a standalone POSIX Threads library
(libcma.sl) that enables developers to use the pthreads API
(Application Programmer Interface) without linking against the entire
DCE library. DCE software included in HP-UX 10.20 and 10.10 is either "default-bundled"
(included in one of the standard Series 700 or Series 800 system
software bundles) or "optional-bundled" (available on the media and
optionally installable). See “Functionality”,
“Default-Bundled Software”, and
“Optional-Bundled Software” for more information. Functionality | |
For 10.20: HP DCE Measurement Service (DMS) to monitor resource utillization
and performance of HP DCE 1.5 servers.
Support for large files APIs; however, there is no support for creating
or operating on large files within DFS.
Integrated login support for CDE/PAM.
Support for context-switching 64-bit machine registers in DCE threads
(libcma and libdce).
Thread-safe wrapper for the new POSIX 1003.1b calls (waitid,
nanosleep, and setrlimit64).
In addition, HP DCE Version 1.5 contains numerous bug fixes. For 10.20: There will be no impact to the general (non-DCE) HP-UX user.
Both shared and archived threaded applications will run on both PA1.1
and PA2.0 machines at 10.20 without recompiling. For 10.20: HP DCE 1.5 supports binary compatibility with HP DCE 1.2/1.2.1,
HP DCE1.3/1.3.1, and HP DCE 1.4/1.4.1/1.4.2. Applications linked with
the archived
HP DCE 1.2/1.2.1 or 1.3/1.3.1 libdce are fully compatible with applications
built with HP DCE 1.5 libraries. These applications can share login
contexts and credentials without loss of data. Binary compatibility for statically-linked HP DCE 1.2/1.2.1/1.3/1.3.1
applications can be disabled, resulting in minor performance gains
and slightly smaller credentials files. By default, binary compatibility
is enabled when HP DCE 1.5 is installed and configured. You may
disable binary compatibility on a per-host basis with the following
command:
dcecp> hostvar set -secbinarycompat off
|
To enable binary compatibility after it has been disabled, do the
following: Issue the command
dcecp> hostvar set -secbinarycompat on
|
Stop and restart DCE daemons.
If using Integrated Login, log out, and log in.
If statically-linked HP DCE 1.2/1.2.1/1.3/1.3.1 application purges
a login context (via sec_login_purge_context) that an HP DCE 1.5
application had created or refresehd, one of the credential files will
not be deleted from the disk. This file is located in
/var/opt/dce/security/creds. The filename will consist of the
unique credential cache id associated with the login context
with a data.db suffix. Administrators can manually remove this file. For information about the U.S./Canada version of HP DCE, see
the HP DCE/9000 Version 1.5 U.S./Canada Version Release Note. Due to the following changes at OSF DCE 1.1, there may be source
code incompatibility with previous HP DCE releases. The
following changes will impact user programs and scripts: Several control programs were replaced with dcecp and several
corresponding daemons no longer exist.
ACL manager facilities were provided withing libdce; it is now
necessary to transition user-written ACL managers to use the
new facilities.
For detailed information about these items, see the release notes

For 10.10: Parity with OSF/DCE Version 1.1 Single Administrative DCE Control Program - dcecp DCE Daemon (combines rpcd and sec_clientd) - dced Hierarchical Cells (limited) Serviceability improvements Security Delegation - intermediary servers can operate on behalf of the
initiating client while preserving identities and ACLs Auditing - tracking of security-related events Extended Generic Security Service Application (GSSAPI) - message passing
applications can use DCE security (includes GDS) Extended Registry Attributes (ERA) - provides single sign-on across non-Unix
platforms and legacy systems by enabling a secure way of associating
additional security information with users and groups Extended Login Capabilities - pre-authentication and password management
allows applications to require access only from trusted machines Group Override - customizes group name mapping from host to host to allow
DCE to adopt to various operating system conventions Internationalization Interfaces - message catalogs for all user-visible
messages Character Code Set Interoperability - allows development of RPC applications
that automatically convert character data from one code set to another IDL Compiler performance enhancements - smaller stub size and support for
a number of new IDL constructs RPC Performance Enhancements - allows additional client sockets during peak
usage and optimizes RPC runtime packets GDS Enhancements - ease of programming and administration DFS/NFS Gateway (was available in HP DCE 1.2) DFS Delegation - files can be passed with initiator's privileges intact Subtree Operations - allows large-scale administrative name changes
within cells Distributed Time Server (DTS) Enhancements - remote administration Enable single threaded Datagram protocol clients Single cds client process per machine Support for Kerberos V5 clients dced/dcecp time synchronization Increase performance of local RPC IDL++ user defined exceptions Compatibility with ServiceGuard Reduced disk and memory consumption for client host machines
