1 ONCplus Release Notes This document contains the most recent product information pertaining to the Open Networking Computing (ONC) product, version B.11.31.01, that is supported on the HP-UX 11i v3 operating system. This document addresses the following topics: • • • • • • • “Announcement” (page 8) “Overview” (page 9) “What's New in ONCplus B.11.31.01” (page 9) “Fixes in ONCplus B.11.31.01” (page 9) “Installation Information ” (page 10) “Features Introduced in ONCplus B.11.
Announcement This version of ONCplus (B.11.31.01) is supported on systems running the HP-UX 11i v3 operating system. 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 release of the operating system. Any changes (for example, defect fixes) to core products are only available to customers by installing HP-UX patches.
NOTE: By default, HP-UX 11i uses the NISv2 protocol, unless the ypwhich or the ypset command is explicitly used with the -v1 option, or an application specifically communicates with the ypbind RPC version 1. Overview Open Network Computing (ONC) is a technology that 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.

An output similar to the following is displayed (these installation instructions assume you have installed the initial ONCplus version shipped with the HP-UX 11i v3): ONCplus 3. B.11.31_LR ONC+2.3 After you have downloaded the ONCplus_B.11.31.01.depot file, move it to the /tmp directory: /tmp/ONCplus_B.11.31.01.depot 4. Verify that the file has downloaded correctly using the swlist as follows: NOTE: You must specify the full path name of the source depot when you use swlist and swinstall commands.
NOTE: The ONCplus B.11.31_LR product can either be installed from the media that contains the previous version of ONCplus or it can be downloaded from the ONCplus web page at:http://software.hp.com 3. Enter the following command to revert to the previous version of ONCplus, ONCplus B.11.31_LR: swinstall -x allow_downdate=true -x autoreboot=true \ -s /tmp/ONCplus_B.11.31.depot ONCplus NOTE: ONCplus contains kernel filesets.
— Locks Locking support is integrated with the NFSv4 protocol. NFSv4 introduces leases for lock management. When a server grants a lock to control the state of a file for a specific period of time, it is known as a lease. — Single Protocol The MOUNT, Network Lock Manager (NLM), and the Network Status Monitor (NSM) protocols are merged into the NFS protocol. Merging these protocols into a single protocol enables easy configuration of firewalls. For more information, see NFS Services Administrator's Guide.
• Concurrent mount or unmount AutoFS performs concurrent mounts and unmounts using the multithreaded automountd daemon. This prevents services from hanging if a server is unavailable. • Reliable NFS ping AutoFS supports a -retry=n mount option for an NFS map entry to configure the ping timeout value. The default timeout value is 10 seconds. The ping command can impose a load on the network if used during normal operations or from automated scripts.
• 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.
• 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. • Ipnodes Support Ipnodes is the new map that stores IPv6 information.
