ONCplus B.11.31.02 Release Notes

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. This 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.

What's New in ONCplus B.11.31.02
All features included in ONCplus B.11.31_LR and ONCplus version B.11.31.01 continue to be
supported in this version of ONCplus. In addition, the following new features are introduced
in ONCplus B.11.31.02 :
New CacheFS Features in ONCplus B.11.31.02
CacheFS introduces the following features:
• Support for ACL's
An Access Control List (ACL) offers stronger file security by enabling the owner of the file
to define file permissions for specific users and groups. HP-UX supports two types of ACL's:
HPUX_ACLS and SYSV_ACLS. HPUX_ACLS are non-POSIX compliant. SYSV_ACLS are POSIX
compliant. This version of CacheFS supports caching for onlySYSV_ACLS. Thus, this version
of CacheFS on HP-UX supports ACLs with VxFS and NFS and not with HFS.
• Support for Logging
A new command, cachefslog is used to enable or disable logging for a CacheFS
mount-point. If logging functionality is enabled, details about the operations performed on
the CacheFS mount-point are stored in a logfile. This logfile contains information on all the
CacheFS mount points using the same cache directory. Use the cachefswssize command
to display the amount of space taken by each of the filesystems in the same cache and the
total size occupied by the cache directory (also known as the working set size). This command
uses the logfile created by the cachefslog command to display the information. The
cachefswssize command used with the -a option displays the information in ASCII
format.
