Distributed Computing Environment (DCE)
HP Distributed Computing Environment (HP DCE) provides a
high-quality, comprehensive, standards-based framework to develop,
administer and use distributed applications.
On HP-UX 11i Version 1.5 (B.11.20), the following products are
available:
• DCE-Core (HP-UX 11i, PA version)
• DCE-IA64-Core (native on IPF platforms)
• DCE-IA64-Tools (native on IPF platforms)
Other DCE Core Services (Security and Cell Directory Services) are not
available in native mode on Itanium-based systems.
DCE-IA64-Core provides DCE-RPC support and includes 32 and 64 bit
version of libdcekt. See New libdcekt.sl and libdcecpkt.sl Libraries in
Chapter 7 for more information. DCE-IA64-Tools is a subset of HP-UX
11i DCE-Core tools containing RPC related application development.
To take advantage of IPF features, RPC applications should be
recompiled. Applications which use DCE-Core service APIs other than
RPC (including rpcd) are not supported in native mode on
Itanium-based systems.
A minimum of 64 MB RAM and 70 MB hard disk space is required for
installation and use of the DCE Clients and libraries on HP-UX 11i
Version 1.5 (B.11.20) systems.
DCE Compatibility
DCE clients can use either the IPF or the PA RPC APIs. DCE clients on
IPF systems can work with DCE servers on a PA system, and DCE
clients on PA systems can work with DCE servers on IPF systems. RPC
applications may have performance degradation and unexpected
behavior in this release.
rpcd is only available in PA mode.
