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.
NOTE: For information on how to migrate from NIS+ to LDAP, see the NIS+ to LDAP Migration Guide available at: http://docs.hp.com/en/J4269-90054/index.html NIS Protocol Version 1 Obsolescence Notice Starting with ONCplus version B.11.31.02, NIS protocol version 1 (NISv1) is no longer supported on the NIS client. However, the NIS server, ypserv, will continue to support NISv1.

3. After you download the ONCplus_B.11.31.08.depot file, move it to the /tmp directory: /tmp/ONCplus_B.11.31.08.depot 4. Verify that the file has downloaded correctly using the swlist command as follows: swlist -d @ /tmp/ONCplus_B.11.31.08.depot If ONCplus is downloaded correctly, the output will include: # # Bundle(s): # ONCplus B.11.31.08 ONC+ 2.3 # # Product(s) not contained in a Bundle: # PHCO_38048 1.
Reverting to a Previous Version of ONCplus You cannot remove the current version of ONCplus with the swremove command. However, you can revert to the previous version of ONCplus. The following section describes how to revert to the previous version of ONCplus. WARNING! 1. On an HP-UX server with ONCplus B.11.31.07.01 installed, NFSv3 does not fully support large files. 2. Directory related operations on an NFS client with ONCplus B.11.31.06 or B.11.31.

3 Features Introduced in previous versions of ONCplus This chapter describes about the features introduced and/or defect fixes in all the previous versions of ONCplus B.11.31. • • • • • • • • • • “Features Introduced in ONCplus B.11.31.07.01” (page 19) “Features Introduced in ONCplus B.11.31.07” (page 19) “Features Introduced in ONCplus B.11.31.06” (page 19) “Features Introduced in ONCplus B.11.31.05” (page 19) “Features Introduced in ONCplus B.11.31.04” (page 20) “Features Introduced in ONCplus B.11.31.
Features Introduced in ONCplus B.11.31.04 ONCplus B.11.31.04 includes both defect fixes and new features. All features introduced in previous ONCplus versions are supported in ONCplus B.11.31.04. The following features were introduced in ONCplus B.11.31.04: New NIS Features in ONCplus B.11.31.04 NIS introduces the following features: • IPv6 support for RPC commands and daemons Phase I ONCplus B.11.31.04 delivers IPv6 support for rpc.rexd, rpc.rwalld, rpc.rusersd, rusers, and rwall commands and daemons.
New NFS Features in ONCplus B.11.31.03 NFS introduces the following features for NFSv4: • File Delegation with Local Access NFSv4 clients support delegation on HP-UX 11i v3. However, until ONCplus B.11.31.03, NFSv4 servers supported delegation with the caveat that no local file access will occur on any delegated file. For example, if the server grants a delegation to the file “/a/b/foo” then any local users on the server need to avoid accessing file “foo” while the delegation is in effect.
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. New NIS Features in ONCplus B.11.31.02 NIS introduces the following features: • Support for IPv6 Protocol The NIS clients and servers are now IPv6 enabled.
operations without immediate interaction with the server. Delegations can be revoked by the server. When another client requests access to the same file, the server revokes the delegation from the first client and grants it to the second client. NOTE: Delegations are disabled by default. If delegations are enabled, they are only supported by applications that access the delegated files remotely via NFS clients. Allowing local access and enabling delegation on a file can corrupt the file.
NOTE: Client failover support is limited to read-only mounts or static filesystems that are not modified often. • Enhanced NFS logging NFS server logging enables an NFS server to provide a record of file operations that are performed on its filesystems. New AutoFS Features in ONCplus B.11.31_LR AutoFS supports the following features: • On-Demand Mounting of Hierarchical Filesystems In earlier versions, AutoFS mounted an entire set of filesystems if they were hierarchically related.
— — • CIFS AutoFS Secure NFS Support If the NFS client supports mounting of secure directories, AutoFS supports Secure NFS filesystems. • IPv6 Support AutoFS provides support for mounting filesystems over IPv6 transports. New CacheFS Features in ONCplus B.11.31_LR CacheFS supports the following features: • Complete Binary Caching CacheFS is commonly used to manage application binaries. This feature enables you to cache a complete binary file in the local cache.
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.
