to read-only mounts and ACLs, there may be additional controls that can alter the permitted access such as: • ID mapping • Mandatory access control • Additional authentication requirements Programs that copy files to update them, rather than updating them in place, often do not preserve ACLs. Some programs that have this problem are gzip, compress, and emacs.
PAGE 51
4.1.4 Some Emacs Command Line Options Fail Compaq ships the Emacs software as it is received from the source. The following command line options do not work as documented in the emacs(1) reference page: -cr, -geometry, -i, -ib, -iconic, -iconname, -in, -internal borderwidth, -mc, -T, and -title. In some cases, a workaround is available by using an appropriate X resource. 4.1.

Supplementary Documents bookshelf of the online Tru64 UNIX documentation. You can configure sendmail using the mailconfig or mailsetup applications. During an update installation, the system will attempt to update your existing sendmail.cf file to comply with this new version. This updated sendmail.cf is compatible with both new and old version of sendmail. To continue using the previous version of sendmail, invoke the following command as root: /sbin/init.

Netscape Web site: http://home.netscape.com/eng/mozilla/4.0/relnotes/unix-4.0.html 4.1.9.2 Netscape Communicator Core Dumps If mailto: Link Is Selected In a Web Page Clicking on a mailto: HTML link in a web page displayed with Netscape Communicator’s Navigator web browser causes Communicator to core dump. This is a known problem scheduled to be fixed in a future release.
PAGE 55
Starting with Netscape Communicator Version 4.5, the Namespace extension to the standard IMAP protocol is used to locate the users folders on the IMAP mail server. This feature will not work if you are using an older IMAP server that does not support the Namespace extension to the protocol. Use the following procedure to customize Netscape Communicator to be able to locate a user’s Trash folder on an old IMAP server: 1.
PAGE 56
4.1.9.7 Installing Open3D Causes Netscape Communicator to Core Dump Netscape Communicator crashes when scrolling Web pages in Navigator or when editing bookmarks on a system with Open3D installed and a PowerStorm 4D5T graphics option after upgrading from Version 4.0D or later of the operating system. In general, Communicator and some other applications become unstable on this system configuration. The workaround is to set shells DISPLAY variable to local:0 before starting Netscape Communicator.
PAGE 57
4.2.1.1 Copying Accounts and UID When copying user accounts via cut and paste or drag and drop, the Allow Duplicate UIDs option in the General Preferences dialog box will be honored. For example, when making a copy of user account that has a UID of 200, if the Allow Duplicate UIDs check box is off (the default), the resulting copy will have a unique UID automatically generated. If the Allow Duplicate UIDs check box is on, then the copy will have an identical UID. The same rules apply to copying groups. 4.
PAGE 58
• You cannot drag and drop items across different instances of Account Manager. For example, if Account Manager A on system 1 and Account Manager B on system 2 are both being displayed on the same workstation, then you cannot drag and drop between Account Manager A and B. Workaround: Use the copy/paste feature to copy users, groups, or templates from Account Manager A to B. • Restriction: Two system administrators should not run two different concurrent instances of Account Manager.
PAGE 59
Workaround: Set passwords through /usr/tcb/bin/dxchpwd or the /usr/bin/passwd command when the C1Crypt Encryption type is chosen. • Do not set a template Encryption Type to C1Crypt as this will invalidate the template. Workaround: Set the C1Crypt Encryption type for the user from the Create/Modify User dialog. • Account Manager does not enforce the minimum/maximum password length limitation when setting passwords.
PAGE 60
Template view to delete the undesired template • Accounts and templates inherit their settings either from locally defined values in their protected password database entry or from the templates that they may reference. All accounts and templates implicitly reference a default template. The default template is not served by NIS. This creates an inconsistency for Account Manager when displaying NIS user accounts and templates on an NIS master.
PAGE 61
Workaround: Restart Account Manager and then delete the template. • After deleting a template, the NIS maps are not remade. Workaround: Manually remake the NIS maps or perform an Account Manager function (for example, Account Modification) that will trigger the maps to be remade. To manually remake the maps do the following: # cd /var/yp # make all 4.2.2 BIND Configuration The following problems apply to configuring BIND servers with the BIND configuration graphical user interface.
PAGE 62
Note that this behavior differs from that of the shutdown command that creates the /etc/nologin file at 5 minutes prior to the shutdown. 4.3 System Administration The following notes apply to system administration. 4.3.1 License Management Facility Allows Year 2000 Testing Certain software license PAKs include expiration dates that currently limit the ability to run software when the date is set well into the future (into the year 2000).
PAGE 63
4.3.2 EISA Configuration Utility Revision Requirements For Tru64 UNIX Version 4.0F and its software supplements, the supported version of the EISA Configuration Utility (ECU) is Version 1.10 or higher. If your system is configured with an EISA bus, you should update the ECU to this supported version. 4.3.3 Open3D Support Consult the Open3D Software Product Description (SPD) before installing Open3D to ensure that this layered product is supported on your system.
PAGE 64
You should consider the following limitations when deciding to implement a dataless environment: 4.3.6 • Hardware limitation of the network – the majority of file system usage performed by any of the clients is done via NFS. This will consume network bandwidth, which, depending on the type and configuration of the network, can become exhausted as more clients are added to the environment.
PAGE 65
4.3.7 Enhanced Security The following notes apply to the use of enhanced security features. 4.3.7.1 Distribution of Enhanced Security Profiles via NIS The following restrictions apply to distributing enhanced security profiles via NIS: • Successful and unsuccessful login attempts for NIS-shared accounts require the completion of the following steps: 1. The master system’s rpc.yppasswdd daemon must respond and update the last successful and last unsuccessful login fields in the prpasswd NIS map. 2.
PAGE 66
the maps if the login notification comes from a Version 4.0D client. Therefore, the yppush operation is only completed when an older client initiates the operation or when it is necessary to clear a failed login count. • Sites that cannot use NIS to share prpasswd information may be able to use NFS to share the /tcb/files and /var/tcb/files directories instead.
PAGE 67
required by those files imposed a limit on how many accounts a system could support. The Enhanced Security routines no longer use the pw_id_map and gr_id_map files. If you are running Tru64 UNIX Version 4.0D or later and still have those files, it is recommended that you remove them to recover the space occupied on the root paritition. 4.3.7.4 Behavior of useradd, usermod, and userdel Commands The useradd command correctly honors the default administrative lock value found in the /.
PAGE 68
• 4.3.9 If you cannot easily reboot your system, note that enabling extended UIDs has very little impact on overall system performance. Insight Manager Agents Insight Manager Agents for Tru64 UNIX include SNMP-based subagents and Web Based Enterprise Management (WBEM) capabilities to present SNMP data in a format viewable by a Web browser.

For both CD–ROM media and DVD–ROM media that contains an ISO-9660 directory structure, Compaq recommends use of the -t cdfs option, as well as the -o noversion or -o rrip option where appropriate. Refer to mount(8) for a description of these options. 4.4 Network and Communications The following notes apply to network and communications software. 4.4.
PAGE 76
4.4.3 Edit the /etc/hosts File After Running netsetup In Tru64 UNIX Version 4.0F, once you configure your interfaces using netsetup, view the /etc/hosts file and make sure that the hostname and the IP address of your system has been added to this file. If not, then you need to add this information in the /etc/hosts file. Edit the /etc/hosts file as a root, and add the following line: Example: 16.60.266.6 example.domain.
PAGE 77
4.4.5 Support for NetRAIN Network Interface Tru64 UNIX now provides support for detecting the physical loss of network connectivity, and subsequent automatic switchover to a working network interface. This feature is called Redundant Array of Independent Network adapters (NetRAIN). NetRAIN uses two or more network interfaces to provide redundancy. Although only one interface at a time is actually used for communication, all interfaces are monitored to ensure that traffic is flowing on each.
PAGE 78
4.4.6 NetRAIN Interface Configuration Change The method for configuring a NetRAIN interface will be improved in a future release of the operating system. If you configure a NetRAIN set in Version 4.0F, or did so in a previous releases of the operating system, you will need migrate your set to the new configuration at that time. 4.4.7 Network Services Fail to Start with NetRAIN Interface If you configure a NetRAIN set in the inet.
PAGE 79
Administration guide. If you do not make this change before adding the new interface, the Common Desktop Environment (CDE) Network Configuration application ( netconfig) and the netsetup utility might yield unpredicable results. This problem will be addressed in a future release of the operating system. If you configure a NetRAIN set, you will need to migrate your set to a new configuration at that time. 4.4.

as follows: nr_max_retries=1 netrain_timeout=100 //The default is 4 //The default is 1000 Alternatively, you can set the nrmaxretry and nrtmoisr values, respectively, when you issue the ifconfig command to create the NetRAIN set. See sys_attrs_netrain(5) and ifconfig(8) for information on NetRAIN parameters.

and provides instructions for converting the files to the new format. The document and conversion utility, README-DB237 and conv185-237, respectively, are located in the /etc/join directory. 4.4.12 TCP Timestamp and Selective Acknowledgement Support Tru64 UNIX Version 4.0F includes support for the TCP Selective Acknowledgment Options (SACK) as well as the TCP Timestamp and PAWS (Protect Against Wrapped Sequence Numbers) options. These TCP options can help improve TCP performance over unreliable networks.

4.6.1 The newfs Command No Longer Searches disktab File Starting with Version 4.0D, the newfs command no longer searches the /etc/disktab file for hard disk geometry information. It now performs an ioctl GETDEVGEOM call to determine the characteristics of a disk. 4.6.2 Using ACLs over NFS For an NFS client to make direct use of ACLs or extended attributes (property lists) over NFS, you must be enable the proplistd daemon on an NFS server.

the /etc/sysconfigtab file. A configurable property list element size for UFS has also been added to the sec subsystem and has been given the attribute name ufs-proplistmax-entry. The value of ufs-proplist-max-entry must be larger than ufs-sec-proplist-max-entry by enough space to hold a property list element header. The sysconfig utility adjusts the ufsproplist-max-entry attribute automatically. The default value of ufs-proplist-max-entry is 8192 bytes.

4.6.4.4 Cleanly Unmount File Systems Before Changing Operating System Versions If a system crashes or goes down unexpectedly due to a loss of power or other similar circumstances, AdvFS will perform recovery the next time that the filesets that were mounted at the time of the crash are remounted after rebooting. This recovery keeps the AdvFS metadata consistent and makes use of the AdvFS log file. Different versions of the operating system use different AdvFS log record types.
PAGE 86
4.6.4.7 Verify Fails on Dual-Mounted Domain While running verify on a dual-mounted domain, it is possible to receive the following type of message: Corruption in frag file type list for frag type 0 Expected to find set ID 36f68cbd.0006ae8c.1.8001 but found set ID 36f68c94.000b1b83.1.8001 This message can be ignored as it does not reflect an actual problem in the frag file, but instead an artifact of the dual-mounted domain. 4.6.4.
PAGE 87
4.6.5.3 Possible Problems Accessing Physical Block 0 with LSM Physical block 0 on Tru64 UNIX disks is typically write protected by default. If a disk is added to LSM by using the voldiskadd utility, physical block 0 is skipped. However, if a partition that includes physical block 0 is encapsulated into LSM by using the volencap, vollvmencap, or voladvdomencap utility, physical block 0 is not skipped. This is not a problem because the file system software already skips block 0 and does not write to it.
PAGE 88
4.6.5.6 The volrootmir Script Supports Only LUN 0 on HSZ Only LUN 0 is supported as a boot device by the console. Hence, you can only mirror the LSM rootvol and swapvol volumes to LUN 0 in an HSZ. Therefore, when you use the volrootmir script to mirror rootvol and swapvol, use only LUN 0 on an HSZ as an argument to the volrootmir script. 4.6.5.
PAGE 89
Note that reset/purge operations will destroy file system data and so should be performed only after all attempts to recover devices and data have failed. 4.6.6 Mounting Associated Products CD-ROMs on Tru64 UNIX Versions Other Than Version 4.0F The Associated Products CD–ROMs (APCDs) can be mounted with the mount command on Tru64 UNIX systems running Version 4.0E or later, as follows: # mount -r /dev/rz4c /mnt To mount the APCDs on releases prior to Version 4.

5 3333333333333333333333 Development Environment Notes This chapter contains notes about issues and known problems with the development environment software and, whenever possible, provides solutions or workarounds to those problems. The following topics are discussed: • General programming • Realtime programming • DECthreads (pthreads) • Profiling • Debugging with dbx • Java Programming 5.1 General Programming The following note applies to general programming. 5.1.
PAGE 92
5.1.2 New DEC C Default Tuning Could Impact Applications That Directly Map I/O Space Applications that directly map and access I/O space with bytes or shorts may be impacted by the new DEC C compiler. The default tuning for the DEC C compiler has advanced its focus from EV4-EV5 architectures to EV56-EV6 architectures. With this change in tuning, the compiler now generates amask-guarded byte and word instruction sequences for some loops.
PAGE 93
5.2.2 POSIX 1003.1b Synchronized I/O and File Truncation POSIX 1003.1b synchronized I/O using file status flags does not apply to file truncation. When file status flags are used to control I/O synchronization, no synchronization occurs for file truncation operations. You can use the fsync() or fdatasync() function to explicitly synchronize truncation operations. 5.2.
PAGE 94
5.3.3 Scheduling Behavior (Contention Scope) In releases prior to Version 4.0, thread scheduling attributes were systemwide. In other words, threads had a system contention scope. Since Version 4.0, thread policies and priorities are, by default, local to the process. No artificial limit exists for thread priorities of these process contention scope threads, the full priority range is accessible by every thread. Previously, there was no way to control the contention scope of a thread.

since the developer must, by intimate knowledge of the machine architecture and implementation, know the correct address to specify relative to the allocated stack. The implementation cannot diagnose an incorrect value because the interface does not provide sufficient information. Using an incorrect value might result in program failure, possibly in obscure ways. 5.3.5 DECthreads Read-Write Locks DECthreads now supports read-write locks.

quadword in memory. If you do and if your project allows, Compaq recommends that you force alignment of each such member variable to a quadword boundary by redefining the variable to be at least eight bytes, or by defining sufficient padding storage after the variable to total eight bytes. Alternatively, you can create one mutex for each composite data object in which adjacent members can share the same quadword in memory.
PAGE 98
5.4.1 Change to hiprof’s Profiling of Threaded Programs The -cputime option of the hiprof(5) profiler now provides an instruction-count profile for threaded programs, the same as the -calltime option, because the CPU cycles reported for kernel-threads by the RPCC instruction can not be mapped to pthread(3) threads. The only significant difference is that the profile is displayed as the number of instructions executed instead of CPU seconds used.

For more information, see Section 4.4.4. 6.4.6 The xnlLanguage Resource Settings May Cause Problems with CDE CDE users should remove any xnlLanguage resource settings from their .Xdefaults files. Those settings are typically left over from one of the user’s earlier DECwindows sessions, where the user selected a language from the session manager’s language menu and then saved that setting.

6.5.1 X11 Font Problem In the Lucida-Typewriter-medium-R-normal fonts, the glyphs for multiplication and division are reversed. The multiplication symbol is where the division symbol should be, and vice versa. If the representation of these glyphs is important to your application, use a different font. 6.6 Internationalization The following notes apply to restrictions on use of internationalization features in the windowing environments. 6.6.

6.6.3 Dxterm Does Not Support Latin-2, Latin-4, and Latin-Cyrillic Characters The dxterm application is not able to display Latin-2, Latin-4 and LatinCyrillic Characters even when the locale is set correctly. Therefore, dxterm should not be used for displaying the following languages: Czech, Hungarian, Lithuanian, Polish, Russian, Slovak, and Slovene. The dtterm application should be used in this case.

Features and Interfaces Scheduled for Retirement 8 3333333333333333333333 This chapter lists features of Tru64 UNIX scheduled to be removed from, or changed in, future functional releases. Users and developers should plan to migrate away from or accomodate changes in these features in the near future. 8.1 DECwindows Applications The following DECwindows utilities and tools will be retired in a future release of Tru64 UNIX.
PAGE 122
8.2 Adobe Display PostScript, Client Libraries, and X Server Extension Adobe has retired their Display PostScript (DPS) product, which includes the client libraries, X Server extension, and various applications and examples. Therefore, Compaq has also retired the Adobe DPS product from Tru64 UNIX. No replacements are available. Customers who have used the Adobe DPS libraries to develop their own applications do not have a migration path.
PAGE 123
Because these obsolete components have been retired from the operating system, they are no longer distributed in new versions, beginning with this version, and they might not be compatible with a future release. They are not supported as part of the Tru64 UNIX product beginning with this release. If you have applications or procedures that depend on the DPS software that is now obsolete, you might want to keep the obsolete DPS software on your system, yet remove the other obsolete software at this time.
PAGE 124
8.4 The -oldc C Compiler The official C compiler for Tru64 UNIX is DEC C. The previous compiler, implemented with -oldc, is no longer distributed in the default subset and will not be installed during a default system installation. The -oldc compiler is still available in this version by installing the CMPDEVENH subset. Any problems reported with -oldc will be addressed in DEC C for Tru64 UNIX rather than in the -oldc compiler. 8.

The obsolete versions should not be used in new designs. These routines formerly resided in libc_r.a and libc_r.so, but were merged into the standard C runtime library. 8.10 POSIX 1003.
PAGE 127
8.13 Nemacs Nemacs Version 3.3.2, a public domain Japanese implementation of emacs, will be retired in a future release of Tru64 UNIX. Mule, a public domain multilingual implementation of emacs, will be carried forward as the replacement functionality for Nemacs. The Nemacs subsets IOSJPNEMACS440 and IOSJPNEMACSSRC440 will be removed from the system. For more information on Mule, refer to the mule(1) reference page. 8.
PAGE 128
The logging format and configuration for DRL will not be compatible with BCL; for example, DRL will require a log size of at least two blocks. The next major release of Tru64 UNIX will automatically reconfigure volumes for DRL when a BCL mirrored volume has a log of two or more blocks. Mirrored volume configurations with a BCL of one block will require manual reconfiguration to continue to take advantage of logging for faster mirror recovery.
PAGE 129
• alloc=size A new construct, alloc=storage-spec[,storage-spec,...], will replace alloc=size. However, the new construct will not allow you to specify sizes for all allocations. You will need to use the lowlevel commands to create subdisks, plexes, and volumes exactly as required. • align=size Two new constructs, diskalign and nodiskalign, will replace align=size, allowing you to specify whether subdisks should be created on cylinder boundaries.
PAGE 130
There are no plans to retire UFS or the AdvFS Migration Tools at this time. 8.21 OSF/Motif Version 1.1.3 The Motif Version 1.1.3 libraries have been provided as run-time services for compatibility with applications that have not yet converted to Motif 1.2. Development support was retired in DEC OSF/1 Version 2.0. In Version 4.0 of the operating system, the Motif 1.1.3 libraries were moved to an optional subset.
PAGE 131
8.24 Graph Utility The /usr/bin/graph utility will be removed in the next major release of Tru64 UNIX. 8.25 The atmsetup Script The atmsetup script is a new utility with Version 4.0D that allows you to set up or change the current configuration of ATM on your system. This script was designed to be an interim solution to simplify the setup process for ATM. In future releases, it will be supplemented and finally replaced by an application in the SysMan suite, with a full graphical user interface.

reports. Tru64 UNIX 2D support will continue for future Tru64 UNIX V4.0n releases and the initial release of Tru64 UNIX Version 5.0 for the TX, HX, and HX+ graphic adapters. The replacement functionality is PCI based systems and graphics devices supported in those systems. In addition, the Open3D PVpci (ZLXp-L1 and ZLXp-L2) graphic adapter support ended in December 1998. The last version of Open3D to support these cards was Open3D Version 4.9.
PAGE 134
8.33 Changed Protected Password Database Format The enhanced security user authentication profiles, originally stored in the protected password files /tcb/files/auth//, are now stored by default in a database format. The convauth program, run for an update installation, will convert existing files into the new format. Support for the original format will be removed in a future release of Tru64 UNIX. 8.
PAGE 135
8.37 XPG3 ctab Locales The XPG3 ctab locales in the obsolete OSFCTABLOC subset will be retired in a future release. These locales were superseded by the XPG4 locales distributed in OSFEURLOC and various subsets in the Worldwide Language Support software on the Associated Products CD (APCD). 8.38 Security Interfaces Several interfaces in libsecurity will be retired in a future release of Tru64 UNIX. These interfaces are not capable of supporting new functionality offered in Tru64 UNIX Version 4.0F.

You can increase the available virtual address space to a maximum of 4 TB by modifying the value of the vm-maxvas attribute in the vm subsystem. For more information about setting this attribute, see the System Configuration and Tuning guide. • Page size The physical page size is 8 KB and cannot be changed. The page size is hardware dependent and is set by the console at boot time. A.1.
PAGE 141
A.1.4 Device Addressing Limits The limits for device addressing are as follows: • Device access There are two types of disk device access: raw (character) and buffered (block). For raw or character access, the uio.uio_offset structure field describes the byte offset within the disk partition. In this release, the uio_offset is an unsigned 64-bit value, allowing an offset up to 264 or 18 exabytes. This value is converted to a physical block/sector number, which is the data transfer start position.
PAGE 142
In this release, the SCSI/CAM driver can address a maximum of 64 buses, with up to 7 device targets for each bus, and a maximum of eight logical unit numbers (LUNs) for each device target. According to these limitations, SCSI/CAM can address a maximum of 3584 devices. • Redundant Array of Independent Disks (RAID) Refer to the following for complete information: – Systems & Options Catalog – Product description literature – Web pages: http://www.digital.com/products.html http://www.storage.digital.

4093 (or 4091, if root and swap volumes are not used). The LSM term subdisk refers to a contiguous portion of a physical disk that can be striped or concatenated with other subdisks to form a plex. A maximum of 4096 subdisks can be associated with one plex, and Compaq supports 4096 subdisks in each disk group or on a system. LSM object names (for example, volumes, plexes, subdisks, and disk groups), volume attribute names (such as user and group), and dxlsm view names are limited to 14 characters. A.1.
PAGE 144
• UNIX File System In this release, the UNIX File System (UFS) file size is limited by the amount of space that can be addressed by the kernel buf structure. The buf.b_blkno structure field, defined as daddr_t, is a 32-bit signed value, and specifies the block/sector offset within a disk partition. The DEV_BSIZE, block or sector size, is 512 bytes. Theoretically, a UFS file system could be 1 TB (213 * 29 ); however, Tru64 UNIX supports only 128 GB.
PAGE 145
An NFS Version 2 or Version 3 client can mount a maximum of 2048 files or directories. • Memory mapped file limit The maximum supported size of a file that can be mapped into memory without segmenting the file depends on the virtual address space limits, as documented in the section on memory limits. • Open files limit The open-max-soft and open-max-hard attributes control the maximum number of open file descriptors per process for all processes. The default value is 4096.
PAGE 146
system performance begins to degrade. • Packetfilter limits The packetfilter pseudo-driver can support up to 255 simultaneous open filters (each filter is usually mapped to one instance of an application program). The packetfilter can support a maximum of 255 devices. Use the pfconfig command to configure packet filters. • Network transfer rates For information on network transfer rates, see the Technical Overview. A.1.
