ONCplus B.11.31.01 Release Notes

• Cache Administering
This feature enables you to perform administrative tasks, such as creation and deletion of
a cache directory. It also enables you to update the resource parameters of the specified
cache directory. In addition, you can view the contents and statistics of the cache.
• CacheFS Write Modes
CacheFS supports two write modes, write-around and non-shared. In the
write-around mode, writes are made to the back filesystem. This is the default write
mode. In the non-shared mode, writes are made both to the front and the back filesystems.
• Cache Consistency Checking
CacheFS periodically checks the files that are stored in the cache, to ensure that the files are
kept up to date. This is the default option. CacheFS provides the following types of
consistency checks:
— noconst Consistency check that is used to disable consistency checking.
— demandconst Consistency check that is performed on demand.
— weakconst Consistency check used to verify cache consistency with the NFS client's
copy of the attributes.
NOTE: Consistency is not checked at file open time.
• Switching Mount Options
You can switch between mount options without deleting or rebuilding the cache. For instance,
you can switch from default to non-shared, or from noconst to demandconst mount
options without recreating the cache.
• Support for Large Files and Large Filesystems
CacheFS supports the maximum file and filesystem sizes supported by both the underlying
front filesystem in which the cache resides and the back filesystem.
CacheFS data structures are 64-bit compliant.
NOTE: CacheFS does not support NFSv4 filesystems.
New NIS Features in ONCplus B.11.31_LR
NIS supports the following features:
• Shadow Mode
Starting with HP-UX 11i v3, NIS supports shadow password mode. This enables the NIS
subsystem to recognize a system in shadow mode and to build, store, and retrieve the
password information accordingly.
NOTE: The encrypted password information used for creating NIS password maps is
present in the shadow file and is visible in the passwd maps (passwd.byname and
passwd.byuid) .
• DNS Forwarding Mode
The DNS Forwarding Mode enables the NIS server to contact the DNS server to service
hosts or ipnodes requests. NIS can automatically fetch the information from DNS and this
operation is transparent to the user or application and can be achieved without any change
to the switch configuration.
