HP Distributed Computing Environment (DCE) Version 3.2 for OpenVMS

5
The DCE Runtime Services for OpenVMS is a prerequisite for use of the DCE Application Developers' Kit
and must be installed first.
5. DCE Cell Directory Server for OpenVMS Alpha
6. DCE Cell Directory Server for OpenVMS I64
The DCE Cell Directory Server provides a consistent mechanism for naming and locating users,
applications, files, and systems within a DCE cell. The DCE CDS also includes the Global Directory Agent
(GDA). The Global Directory Agent provides a means of linking multiple CDS namespaces via the Internet
Domain[R] Name Server (BIND), X.500 or LDAP.
7. DCE Security Server for OpenVMS Alpha
8. DCE Security Server for OpenVMS I64
The DCE Security Server allows users controlled access to information in a distributed computing
environment safely and confidentially. The DCE Security Server accomplishes this through two services:
• DCE Authentication Service allows users and resources to prove their identity to each other.
The DCE Authentication Service is based on Kerberos, which requires that all users and
resources possess a secret key.
• DCE Data Integrity Service protects network data from tampering. Cryptographic checksums
automatically generated by RPC enable DCE to determine whether data has been modified or
corrupted in transmission.
To run the DCE Security Server, a DCE-SECURITY license must be loaded on that system. Additionally,
the use of DCE Security requires that a DCE CDS Server be run on at least one system within the DCE
cell.
To run the DCE CDS Server, a DCE-CDS license must be loaded on that system. Additionally, the use of

NEW FEATURES IN V3.2:
HP DCE V3.2 for OpenVMS Alpha and OpenVMS I64 is an enhanced version
of its previous Version 3.1. In addition to including all the new features of 3.1, HP DCE V3.2 also
provides the following new features:
• I64 Support
Version 3.2 is the first ported version of HP DCE on OpenVMS I64
• DCE RPC Now Supports IEEE Floating Point Type
DCE RPC for OpenVMS now supports both G_FLOAT and IEEE floating point types on Alpha
and I64 platforms. The default floating-point type on Alpha platform remains G_FLOAT. The
default floating-point type on I64 is IEEE_FLOAT. DCE RPC Application developers would
need to use rpc_set_local_float_drep call in their application for using the non-default floating
point type
