ONCplus B.11.31.18 Release Notes (762806-002, June 2014)

• Cache Consistency Checking
CacheFS checks the files that are stored in the cache to ensure that the files are kept up to
date. With this version of CacheFS, the default behavior is that the consistency checking used
can impact CacheFS performance. Following are mount options that can be used to change
the type of consistency checking performed by CacheFS:
◦ noconst Disable consistency checking.
◦ demandconst Consistency checking is performed on demand.
◦ weakconst Consistency check used to verify cache consistency with the NFS client's
copy of the attributes. weakconst is the consistency checking level similar to the default
behavior in HP-UX 11i v2.
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. This operation is
transparent to the user or application and can be achieved without any change to the switch
configuration.
• Multi-homed Node
NIS supports systems with more than one network address. This enables an NIS client to obtain
the closest address of the host when it looks for a specific host name.
• IPv6 Data Support
NIS retrieves the IP addresses corresponding to the host name and identifies the IPv6 address
formats. IPv6 data support is provided with ONCplus, but NIS is not IPv6 enabled.
