8    Features and Interfaces Scheduled for Retirement

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 have been retired from Tru64 UNIX. These dx* tools and utilities, commonly known as DECwindows, have been replaced by the dt* tools in Common Desktop Environment (CDE) that were introduced in Version 4.0. The replacement applications are listed in Table 8-1. Not all of the dx* applications that have been retired have a replacement due to the limited use or capability of that specific tool or utility.

Table 8-1:  Retired DECwindows Applications

It is recommended that you migrate to the dt* tools and utilities or other options as soon as possible.

The CDA applications in Table 8-2 have also been retired.

Table 8-2:  Retired CDA Applications

8.2    Adobe Display PostScript, Client Libraries, and X Server Extension

Adobe Systems Incorporated has retired its Display PostScript (DPS) product, which includes the client libraries, X server extension, and various applications and examples. Therefore, the Adobe DPS product has been retired from Tru64 UNIX. No replacements will be available. Customers who have used the Adobe DPS libraries to develop their own applications will not have a migration path.

The following Adobe applications have been retired and are no longer included with the Tru64 UNIX operating system:

• dpsclock

• dpsexec

• draw

• fontview

• libdps.a and libdps.so

• libdpstk.a and libdpstk.so

• libpsres.a and libpsres.so

• lib_adobe_dps.so

• makepsres

• pswrap

• scratchpad

• showps

• texteroids

• wonderland

• xepsf

• All Adobe fonts under /usr/lib/X11/fonts/Type1Adobe

The following applications, which use Adobe DPS, have been retired and are no longer included with the Tru64 UNIX operating system:

• dxvdoc

• dxbook

• dxnotepad (internationalized version in WorldWide Language Support software on the Associated Products CD-ROM)

During an update installation from Version 4.0D or Version 4.0F to Version 5.0, the DPS commands, libraries, and documentation noted above are marked by the installation update procedure as obsolete inventory and then removed from the system later in the procedure.

Because these obsolete components have been retired from the operating system, they are no longer distributed, and they may 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 has become obsolete, you may wish to have the obsolete DPS software remain on your system, yet remove the other obsolete software at this time.

To do this, you can edit the file /var/adm/smlogs/upd_obsolete_files so that the DPS software components are not listed, before you perform the updadmin procedure.

If you remove the DPS components from your system using the updadmin utility, you will have the opportunity to archive all of the obsolete components. If you prepare an archive copy, and later discover a dependency on the obsolete DPS components, you can restore them to the system from the archive copy.

If you remove the obsolete DPS components without making an archive copy, there is no way to restore them from the product distribution media for the current release.

The freeware application gv may be a suitable replacement for showps. It has a different user interface than showps but has no dependency on the obsolete DPS software libraries.

Some of the freeware applications delivered with Version 4.0D had dependencies on the DPS client libraries. Those applications have been rebuilt using the GhostScript libraries available on the freeware distribution media.

8.3    Nonconforming Curses Library

Version 4.0 of the operating system included a new X/Open Compliant Internationalized Curses library. This library was not binary compatible with previous versions of the Curses library, so compatible binaries (named libcurses.a and libcurses.so) were shipped in separate directories for Version 4.0.

These compatible binaries have been retired and removed from this release of Tru64 UNIX.

8.4    The -oldc C Compiler

The C compiler for DIGITAL UNIX has been officially replaced by Compaq C for Tru64 UNIX. The older compiler is no longer distributed in this release of Tru64 UNIX. The -oldc switch, which was used to request the old C compiler from the cc command in previous versions, is no longer supported. The cc command now issues an error if the -oldc switch is specified.

8.5    The dbx Debugger

It is recommended that you begin using the ladebug debugger now and report any problems. This will provide a higher quality replacement when dbx is finally retired.

8.6    Tru64 C Compiler Default Change from -std0 to -std

The default language mode for the Tru64 UNIX C compiler has changed from -std0 to -std.

You can revert back to the previous default language mode by adding the -std0 flag to the cc command line, the /usr/ccs/lib/cmplrs/cc/comp.config file or the $DECC_CC or $COMP_HOST_ROOT environment variable definitions.

8.7    Change in struct utmp, struct utmpx, and struct lastlog

To bring them into compliance with several UNIX and Internet standards, the struct utmp, struct utmpx, and struct lastlog structures have been changed. These changes affect the /usr/include/utmp.h, /usr/include/utmpx.h, and /usr/include/lastlog.h files :

• The time field in the struct utmp structure has changed from a time_t structure to a struct __ut_timeval structure (to be consistent with the /usr/include/utmpx.h file).

• The ut_host field size (in the struct utmp and struct utmpx structures) has been increased to comply with relevant Internet RFCs.

• The ll_line and ll_host manifest constants in the/usr/include/lastlog.h file have changed to allow their sizes to correspond to the ut_line and ut_host fields in struct utmp and struct utmpx structures.

These changes also affect the format of the /var/adm/utmp, /var/adm/wtmp, and /var/adm/lastlog files. The following conversion programs are supplied:

• /usr/lbin/wtmpconvert

• /usr/lbin/llconvert

The programs enable you to convert your existing /var/adm/wtmp and /var/adm/lastlog files to the new format or convert new format files to the old format for use by existing programs. See the corresponding reference pages for more information.

8.8    C Language long double Type Changing to 128 Bits

As of Tru64 UNIX Version 5.0 the default size of the C language long double type changed from 64 bits to 128 bits. This allows applications to perform mathematical calculations on larger numbers and with more precision than was possible with the previous long double type. Prior to Version 5.0, the long double type was the same size as the double type (64 bits).

If an application was linked using an earlier version than Tru64 UNIX Version 5.0, there is one binary incompatibility that may affect the application. If the application was linked using the -call_shared switch, it can experience an incompatibility with the new default related to the input and output of long double types. Previously, printf, scanf, and similar functions interpreted the format code %Lf (capital L followed by f) as a 64-bit long double type. Now, the format code %Lf specifies a 128-bit long double type.

8.9    C Library Functions and POSIX P1003.1C

asctime_r     getgrnam_r    getpwuid_r    localtime_r   readdir_r
ctime_r       getlogin_r    gmtime_r      rand_r        ttyname_r
getgrgid_r    getpwnam_r
 

Binary compatibility is maintained in Version 4.0G; however, these routines will be retired in a future release of the operating system. 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 1003.4a (draft 4) pthread Routines in DECthreads

The POSIX 1003.4a, Draft 4 interface of POSIX Threads (formerly DECthreads) will be retired in a future release of Tru64 UNIX. Applications that were written using the POSIX 1003.4a, Draft 4 API should be migrated to the IEEE Std. 1003.1-1996, POSIX System Application Program Interface provided by POSIX Threads. The POSIX 1003.1c standard interface is the most portable, efficient, and powerful programming interface offered by POSIX Threads. A compatibility mode for the Draft 4 POSIX 1003.4a API has been provided to ease migration. This compatibility mode will be removed in a future release.

8.11    DECthreads CMA Interface

The CMA interface of POSIX Threads (formerly DECthreads) is obsolete beginning with this release. Obsolescence means that while the CMA API continues to exist and is supported in Tru64 UNIX, CMA routines are no longer documented or enhanced. It is recommended that you port your CMA-based application to the IEEE Std 1003.1-1996, POSIX System Application Program Interface provided by POSIX Threads Library.

8.12    Asynchronous I/O Binary Compatibility

Data structures for asynchronous I/O, like aio_read() and aio_write(), changed between Version 3.2 and Version 4.0 of the operating system. The kernel currently handles these differences so that applications built under Version 3.2 continue to run when executed on Version 4.0x.

In the next major release of the operating system, support for applications built under Version 3.2x using asynchronous I/O will be discontinued. You will need to recompile and relink these applications to run under Tru64 UNIX Version 4.0D or higher.

8.13    Nemacs

Nemacs Version 3.3.2, a public domain Japanese implementation of Emacs, has been removed from this release of Tru64 UNIX. Mule, a public domain multilingual implementation of Emacs, has been carried forward as the replacement functionality for Nemacs. The Nemacs subsets IOSJPNEMACS500 and IOSJPNEMACSSRC500 will be removed from the system. For more information on Mule, refer to the mule(1) reference page.

8.14    Berkeley Software Distribution TTY-NAME

The intent to retire the BSD TTY-NAME namespace was announced in DEC OSF/1 Version 3.0. This functionality will be retired in a future release.

8.15    SCSI Device Names

Support for rz and tz SCSI device names will be retired in a future release of Tru64 UNIX. Any code that derives knowledge about a device from the ASCII name or minor number may be impacted.

All code that uses the current namespace will be compatible until the change occurs because a mechanism that ensures binary compatibility has been provided.

8.16    The -x and -p Options in addvol and mkfdmn

The -x and -p options to the addvol and mkfdmn commands allow you to set the per-volume bitfile metadata table (BMT) when you create a new volume or file domain. Users typically set the BMT to prevent an extent exhaustion problem.

In Version 4.0D and later, the limitations in the operating system that caused the extent exhaustion problem were removed, hence the -x and -p options are no longer needed and will be retired in a future release.

8.17    LSM Block Change Logging (BCL)

The Logical Storage Manager Block Change Logging (BCL) feature has been retired. It has been replaced with Dirty Region Logging (DRL). DRL logs regions instead of blocks for writes to LSM mirrored volumes. For most environments, DRL provides the same ability as BCL to quickly resynchronize mirrors after a failure, but with considerably less logging overhead.

The logging format and configuration for DRL is not compatible with BCL. Therefore, this release provides support to automatically migrate and reconfigure mirrored volumes from BCL to DRL where possible. However, some existing mirrored volume configurations with BCL may require manual reconfiguration to continue to exploit logging for faster mirror recovery.

8.18    LSM volassist Command Syntax

In Version 5.0 of Tru64 UNIX, the syntax of the volassist changed. It no longer supports the following constructs:

• [!]medianame,offset

  You will still be able to use [!]medianame,offset construct but you cannot specify an offset. If you need to specify an offset, you will have to use the low-level commands to create subdisks, plexes, and volumes exactly as required.

• alloc=size

  A new construct, alloc=storage-spec[,storage-spec,...], replaces alloc=size. However, the new construct does not allow you to specify sizes for all allocations. You need to use the low-level commands to create subdisks, plexes, and volumes exactly as required.

• align=size

  Two new constructs, diskalign and nodiskalign, replace align=size, allowing you to specify whether subdisks should be created on cylinder boundaries. If you require the ability to specify alignments for all allocations, you need to use the low-level commands to create subdisks, plexes, and volumes exactly as required.

8.19    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. Applications requiring the libraries will see an error from the loader, requiring you to install the optional subset. This optional subset will be removed from the product in a future release.

8.20    XIE Version 3.0 X Client Extension

Tru64 UNIX Version 4.0G supports XIE Version 5.0. Support for XIE Version 3.0 server extensions was removed in Version 4.0. Client support will be removed in a future release.

8.21    Microsoft Sound Board Driver

The driver binaries are now available as part of the Multimedia Services for Tru64 UNIX kit on the Tru64 UNIX Associated Products, Volume 1 CD-ROM in the MMEDRVMSB subset.

The following files will be removed from the base operating system:

• /usr/sys/BINARY/msb.o

• /usr/sys/include/io/dec/eisa/msb.h

• /usr/sys/include/io/dec/eisa/msb_reg.h

You can also obtain support for this device from the Multimedia Services for Tru64 UNIX kit that is located on the Software Products Library CD-ROM. Support is also factory-installed on all AlphaStation Tru64 UNIX packaged systems. The license for this product is bundled with AlphaStations so that you can use it at no additional cost.

8.22    Graph Utility

The /usr/bin/graph utility will be removed in the next major release of Tru64 UNIX.

8.23    The atmsetup Script

The atmsetup script introduced in Version 4.0D has been superceded by a new application. The new application is part of the SysMan suite, and provides a full graphical user interface. The atmsetup command now invokes this new SysMan application.

You can access the atmsetup script by including the -old flag with the atmsetup command.

The atmsetup script will be retired in a future release of Tru64 UNIX.

For more information on how to use the new atmsetup, application see the atmsetup(8) reference page and the Asynchronous Transfer Mode guide.

8.24    Remote Prestoserve Support

Prestoserve support for remote operations has been retired. This means that the -h option of the presto command is no longer supported.

Users who require the ability to perform presto operations remotely can do so by using telnet, rlogin, or rsh to gain access to a shell on the remote system and then performing the operation locally.

8.25    Installupdate -i Option

The -i option to the /sbin/installupdate command will be retired in a future release of the operating system.

The -i option currently allows you to interactively select kernel components after the new software subsets have been installed. Starting with the next major release, this flag will be unnecessary because you will be able to interactively select optional kernel components at the beginning of the update installation process, prior to software installation. These kernel components will be built into the kernel automatically during the kernel build phase at the end of the update installation; therefore, you need not be present at that time.

8.26    Different awk Versions

The gawk and oawk versions of the awk command have been retired. Only the XPG4-compliant version of the awk command is supported in this release. Scripts that use variations of the awk command should access the /usr/bin/awk version.

8.27    The secsetup Script

The /usr/sbin/secsetup script, used to configure Enhanced Security authentication support, has been retired in this release of Tru64 UNIX. It has been moved to the OSFOBSOLETE subset. The script has been replaced by the secconfig application. The secconfig application is a graphical user interface and is integrated with the SysMan utilities.

8.28    Open3D TURBOchannel and PVpci Device Support

The following Open3D devices have been retired in this release of Tru64 UNIX:

• PV-L

• PV-M

• PV-P

These devices are also known as:

• ZLX-L1, L2

• ZLX-M1, M2

• ZLXp-L1, L2

Open3D Version 4.4 is the last version of Open3D that supports the PV-L and PV-M cards. Open3D Version 4.9 is the last version of Open3D to support the PV-P graphic adapters.

Additionally, 3D support for the HX+ and TGA has been retired. These are also known as the ZLX-E1, E2, E3; and ZLXp-E1, E2, E3. DIGITAL UNIX 2D support will continue for the initial release of Tru64 UNIX Version 5.0 for these cards. The initial release of Tru64 UNIX Version 5.0 will also be the last release to support the HX and TX graphics adapters.

The replacement functionality is PCI-based systems and graphics devices supported on those systems.

8.29    System Management Utilities

The following setup scripts have been retired in this release:

• bindsetup

• netsetup

• nfssetup

• ntpsetup

These scripts have been replaced by tasks that you can perform by running the SysMan Menu and navigating to the desired item, or directly from the command line by using the appropriate menu accelerator. The following table maps the replacement functionality and accelerator:

Do not use these scripts to configure systems in a TruCluster environment. For more information, see the reference pages for the retired scripts or the Network Administration guide.

8.30    Changed Protected Password Database Format

The /usr/sbin/audit_setup script, used to configure auditing support, will be retired in a future release of the operating system. It will be replaced by the audit_config, which is a SysMan application that provides a full graphical user interface.

8.32    VM Subsystem ubc_nfsloopback Variable Is Obsolete

This configuration variable was needed in some TruCluster configurations with previous versions of Tru64 UNIX to avoid a recursion deadlock with NFS loopback-mounted file systems. In those configurations, setting the ubc_nfsloopback VM subsystem variable to 1 prevented the deadlock.

The file system code in Tru64 UNIX Version 4.0G has been modified to prevent the deadlock, which removes the need for the ubc-nfsloopback variable.

If the variable is not removed from /etc/sysconfigtab, it will not cause a problem. However, after the kernel is loaded by the firmware, the console generates the following message to indicate that the variable is still present in /etc/sysconfigtab:

sysconfigtab:  attribute ubc_nfsloopback not in subsystem VM
 

8.33    libsecurity.a

The archive form of the enhanced security library (libsecurity.a) has been retired. If you want to link against libsecurity use the shareable form, libsecurity.so.

8.34    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-ROM (APCD).

8.35    Security Interfaces

The associated data structures listed in Table 8-4 have been retired as well.

Table 8-4:  Retired libsecurity Interfaces Associated Data Structures

8.36    The ogated Routing Daemon

The ogated daemon (the old version of the gated routing daemon) will be retired in a future release of Tru64 UNIX. If you use the ogated routing daemon, you should migrate to the gated routing daemon, which supports a superset of functionality in the ogated daemon.

8.37    PEX Extensions

Starting with Open3D Version 4.8, support for the PEX extension to the X Server has been retired. The extension libraries still ship on the Open3D product, but no support is available for them.

8.38    NL* and NL* libc Interfaces

A Worldwide Portability Interface (WPI) for internationalization based on the XPG4 standard was introduced in Version 2.0 of the operating system. Because the WPI interfaces supersede the libc OSF/1 proprietary interfaces, all libc interfaces that begin with the letters NL or NC will be removed in a future release of the operating system.

8.39    DEC Ada RTL

DEC Ada (UPI - 0HM) and DEC Ada PDO (UPI - 0VS) will be retired in a future release of Tru64 UNIX.

8.40    System V Environment

Tru64 UNIX provides 80 percent of the System V Interface Definition (SVID) standard, as verified by the SVVS 3 and SVVS 4 test suites. As a result, Tru64 UNIX contains a substantial number of System V Release 4 (SVR4) features and delivers the highest composite SVR4 conformance of any implementation. SVR4 functionality will be further expanded in the base operating system when the System V Environment re-engineering is complete, eliminating the need for the layered product. A migration plan for upgrading to the appropriate version of the Tru64 UNIX base operating system has been developed to assist customers who currently use the System V Environment layered product. The System V Environment (SVE) product is not available as a separately licensed layered product with the Tru64 UNIX Version 5.0 family. Instead, many of its features are being re-engineered and will be merged into the Tru64 UNIX operating system in future releases.
