HP Distributed Computing Environment (DCE) Version 3.2 for OpenVMS

2
• RPC_UNSUPPORTED_NETIFS & RPC_SUPPORTED_NETADDRS Support has been
added for restricting network interfaces and addresses via the logical names
RPC_UNSUPPORTED_NETIFS and RPC_SUPPORTED_NETADDRS. This can be useful
in cluster environments and on systems with more than one network interface.
• Hierarchical Cells can be registered in another cell’s CDS namespace, allowing the creation
of a multi-level control structure.
• Extended Registry Attributes allow users to modify the security registry schema to create and
maintain attribute types and to create and maintain instances of those types.
• An Auditing subsystem creates an Audit daemon to maintain filters and provide the central
audit trail file. Specified APIs provide the functions that are used to detect and record critical
events. The audit service is controlled via the DCE control program (dcecp).
• The management features of DCE R1.2.2, including the dce daemon (dced), and dce control
program (dcecp).
• Documentation available in HTML format: DCE documentation from The Open Group and
HP is provided in HTML format to allow reading on-line from a web browser.
The DCE Threads Service which provides user-context multiprocessing functionality is provided as part of
the OpenVMS Operating System.
The DCE for OpenVMS product family currently consists of eight separate products, four on OpenVMS
Alpha, and four on OpenVMS Industry Standard 64 (I64) to provide customers with maximum flexibility
for configuring a DCE environment, known as a DCE cell. The products and features include:
• DCE Runtime Services for OpenVMS, which is required for all systems participating in the
DCE cell. The DCE Runtime Services kit includes DCE client functions as well as DCE
administration tools.
• DCE Application Developers' Kit for OpenVMS, which is required for developers of
distributed applications, but optional for other users. The DCE Application Developers' Kit
provides programmers with all the DCE API's and the Interface Definition Language (IDL).
IDL is an easy-to-use, ANSI C-based language for writing remote procedure calls.
• DCE Cell Directory Server, at least one of which is required for each DCE cell. The DCE
CDS Server is a central repository containing information about the location of resources in
the DCE cell. It allows access to resources by a single name, regardless of physical location.
• DCE Security Server, at least one of which is required for each DCE cell. The DCE Security
Server protects resources from illegal access and provides secure communications within and
between DCE cells.
