1 ONCplus Release Notes This document contains the most recent product information pertaining to the Open Networking Computing (ONC) product, version B.11.31.07, which is supported on the HP-UX 11i v3 operating system. This document addresses the following topics: • • • • • • • • • • • • • “Announcement” (page 6) “Overview” (page 6) “What's New in ONCplus B.11.31.07” (page 7) “Fixes in ONCplus to date” (page 7) “Installation Information ” (page 10) “Features Introduced in ONCplus B.11.31.
Announcement This version of ONCplus (B.11.31.07) 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 operating system. Any changes (defect fixes, for example) to core products are only available to customers by installing HP-UX patches. For HP-UX 11i v3, ONCplus is available as an Independent Software Unit (ISU).
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.
Table 1-1 ONCplus Software Fixes (continued) CR ID Description ONCplus Version QXCR1000857730 On NFS mounts with tcp and noac options, setting nfs3_bsize tunable to a value greater than or equal to 64KB, results in file sizes more than its actual size at the time of their creation or modification. B.11.31.
Table 1-1 ONCplus Software Fixes (continued) CR ID Description ONCplus Version QXCR1000759153 AutoFS fails to mount with NFSv4 after an update from HP-UX 11i v2 to HP-UX 11i v3. B.11.31.03 QXCR1000769108 A system runs out of memory and hangs when NFS and NFS file locking are heavily used. B.11.31.03 QXCR1000763503 An AutoFS UDP NFS mount fails with the error message "Couldn't bind to B.11.31.03 reserved port". QXCR1000764069 Added support for SecureNFS in a Serviceguard environment. B.11.31.
Table 1-1 ONCplus Software Fixes (continued) CR ID Description ONCplus Version QXCR1000583678 CacheFS panics when issuing simultaneous mount requests with a full front B.11.31.01 file system. QXCR1000585325 The nfstat.h header file incorrectly defines MAX_RFS4_PROC_NO as 40. B.11.31.01 QXCR1000585353 An NFS server panics due to a data page fault. B.11.31.01 QXCR1000585618 Added a new private kctune parameter "klm_log_level" to enable KLM (kernel lock manager) logging. B.11.31.
3. After you download the ONCplus_B.11.31.07.depot file, move it to the /tmp directory: /tmp/ONCplus_B.11.31.07.depot 4. Verify that the file has downloaded correctly using the swlist command as follows: NOTE: You must specify the full path name of the source depot when you use swlist and swinstall commands. swlist -d @ /tmp/ONCplus_B.11.31.07.depot If ONCplus is downloaded correctly, the output should include: # # Bundle(s): # ONCplus B.11.31.07 ONC+ 2.
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.
4. To revert to the previous version of ONCplus enter the following command: swinstall -x allow_downdate=true -x autoreboot=true \ -s /tmp/ONCplus_B.11.31.depot ONCplus NOTE: ONCplus contains kernel filesets. Thus swinstalling the product results in a system reboot after the installation is complete. Features Introduced in ONCplus B.11.31.06 ONCplus B.11.31.06 includes both defect fixes and new features. This version of ONCplus supports all features included in previous ONCplus versions.
and ensure that their local applications are compatible with the expanded group limit. ONCplus has the following limitations regarding the number of groups per user: • • The records, which can be passwords, groups, hosts, netid, etc., in the NIS database are limited to 1024 characters. The use of extremely long group names can cause the 1024 character limit to be exceeded even with just 20 groups, and in that case, such long records will not be included in the NIS database.
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 should 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.
