ONCplus B.11.31.09.01 Release Notes HP-UX 11i v3 (September 2010)

Overview
Open Network Computing (ONC) comprises core services that enable administrators to implement
distributed applications in a heterogeneous distributed computing environment. It also includes
tools to administer clients and servers.
ONC consists of the following components:
• Network File System
The Network File System (NFS) is a distributed filesystem that provides transparent access
to files and directories that are shared on remote systems.
• AutoFS
AutoFS is a client-side service that enables automatic mounting and unmounting of
filesystems.
• CacheFS
The Cache Filesystem (CacheFS) is a general purpose filesystem caching mechanism that
improves the performance of client side applications when working with NFS servers.
CacheFS client performance is improved by caching data to a fast local file system instead
of going over the wire. Caching data results in reduced server and network load because
the clients have already cached a copy of the data and send fewer requests to the server.
• Network Information Service
Network Information Service (NIS), previously called “Yellow Pages,” is a distributed
database system that enables the maintenance of commonly used configuration information
on a master server and propagates the information to all the hosts in the network.
Availability of ONCplus as an ISU
Prior to the HP-UX 11i v3 release, ONC was delivered as a core product called NFS. Core products
cannot be released independent of the operating system. Any changes (defect fixes, for example)
to core products are only available to customers by installing HP-UX patches.
For HP-UX 11i v3, ONCplus is available as an Independent Software Unit (ISU). With the ONCplus
ISU, both defect fixes and new features are made available to customers by installing newer
versions of ONCplus.
The ONCplus ISU will be updated on an ongoing basis and will include the latest ONC updates
and defect fixes. When looking for ONC updates, you are encouraged to review the content of
the latest ONCplus ISU and consider updating to the most recent ONCplus ISU version.
NOTE: All ONCplus ISU versions are available at:

NIS+ Obsolescence Notice
Network Information Service Plus (NIS+) is a distributed database system that enables the
maintenance of commonly used configuration information on a master server and propagates
the information to all the hosts in the network. Starting with HP-UX 11i v3, NIS+ is no longer
supported. Hewlett-Packard recommends that users migrate to LDAP.
