2    Features and Interfaces Scheduled for Retirement

This chapter provides information on features that have been retired from the operating system or that are scheduled to be removed from, or changed in, future releases. This information is provided so that users and developers can migrate away from these features in the near future.

2.1    Retired in This Release

The following notes provide information on features that have been retired in this release. These changes were announced in previous releases.

2.1.1    Performance Manager CDE GUI

The Performance Manager CDE GUI has been retired. Performance management functions are available using the collect utility. The collect utility includes a command line interface and a graphical user interface.

2.1.2    COM for Tru64 UNIX

2.1.3    DECmigrate

DECmigrate has beeen retired in this release of the operating system. This retirement includes the removal of the mxr command, the libmxr.so library, and the mxr(1) reference page.

2.1.4    iPlanet Directory Server

iPlanet Directory Server has been retired in this release of the operating system. This product has been replaced by the OpenLDAP Directory Server.

2.1.5    AdvFS Subsystem Attributes

The following AdvFS subsystem attributes have been retired:

The functionality provided by these attributes has been replaced by new dynamic kernel algorithms to optimize system performance.

2.1.6    AdvFS Fragment Attributes

The AdvFS subsystem attributes AdvfsMinFragGrps and AdvfsMaxFragGrps have been retired.

2.1.7    C++ Run-Time Libraries libtask and libcomplex

The libtask and libcomplex C++ run-time libraries have been moved to the retired subsets directory (Tru64_UNIX_Retired) on the Associated Products, Volume 2, CD-ROM. If you have code that uses the nonstandard complex class in the library, we recommend that you use the template complex class defined in the C++ Standard Library. If you have code that uses libtask, we recommend that you use the POSIX Threads Library.

2.1.8    Unsupported Kernel Object Subsets

The following kernel object subsets have been moved to the obsolete subsets directory (Tru64_UNIX_Obsolete) on the Associated Products, Volume 2, CD-ROM:

OSFBINOBJECT540 Main kernel objects
OSFHWBINOBJECT540 Hardware kernel objects
OSFADVFSOBJECT540 AdvFS kernel objects
OSFLSMOBJECT540 LSM kernel objects
OSFATMOBJECT540 ATM kernel objects

2.2    Features and Interfaces Scheduled for Retirement in Future Releases

The following notes contain information on features and interfaces that will be retired in future releases. This information is provided so you can begin planning for the time when these features are retired.

2.2.1    The emxmgr Utility

The emxmgr utility will be retired in a future release of the operating system. The functionality of this utility is now available in the hwmgr utility (hwmgr show fibre). For more information, see hwmgr_show(8) or enter the hwmgr -help show command.

2.2.2    The automount Utility

The automount utility will be retired in a future release of the operating system. This utility is being replaced by the autofs utility. Instructions for migrating from automount to autofs are provided in the Network Administration: Services manual. Instructions for migrating from automount to autofs in a TruCluster environment are provided in the Cluster Administration manual.

2.2.3    POSIX Threads Metering

The metering features of the POSIX Threads Library will be retired in a future release of the operating system. These features are described in the Guide to the POSIX Threads Library. If you want to collect statistical and historical information on synchronization objects, use Visual Threads, which is a tool that you can use to analyze and debug multithreaded programs.

2.2.4    SCSI Device Names

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

All code that uses the current name space will be compatible until the retirement because a mechanism that ensures binary compatibility has been provided.

The compatibility name space can be used to access devices in only the old, limited address space, and the new names can be used to access devices in only the new extended address space.

2.2.5    XIE Version 3.0 X Client Extension

This version of the operating system supports XIE Version 5.0. Support for XIE Version 3.0 server extensions was removed in Version 4.0 of the operating system. Client support will be removed in a future release.

2.2.6    ATM IP Switching

The operating system provides limited support for IP switching over ATM, based on the Ipsilon Networks Inc. reference model (RFC 1953 and 1954). This support will be retired in a future release.

IP switching support is provided in this release for backward compatibility only. Do not use it to develop new applications. Other methods of carrying IP over ATM, including classical IP and LAN emulation, will continue to be supported.

2.2.7    The ogated Routing Daemon

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

2.2.8    DEC Ada RTL

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

2.2.9    Event Report Formatter (uerf)

The Event Report Formatter (uerf) will be retired in a future release. The uerf command is not certified to be Y2K compliant. Depending on your system, use either Compaq Analyze or DECevent.

2.2.10    Tcl Version 7.6 and Tk Version 4.2

Tcl Version 7.6 and Tk Version 4.2 will be retired in a future release. This release contains Tcl/Tk Version 8.2.

Tcl Version 7.6 and Tk Version 4.2 have been moved to the optional subsets OSRETIREDTCL76510 and OSRETIREDTK42510. These subsets will install under the /usr/opt/obsolete directory and only contain the run-time environment. Header files and reference pages are no longer included.

2.2.11    The dxlsm Interface

The CDE/X11 graphical Logical Storage Management tool, dxlsm, will be retired in a future release. The dxlsm interface is superseded by the new LSM Storage Administrator, lsmsa, which was introduced in Version 5.0 of the operating system.

Both the dxlsm and the lsmsa interfaces are installed from the OSFLSMX115xx subset.

We recommend you begin using the lsmsa interface to manage your LSM configurations.

2.3    Hardware Support Retirement Notices

To allow for future growth and enhancements to the operating system, it is necessary to retire support for some of the existing hardware. This section provides information on hardware support that has been retired in this release and hardware support that will be retired in future releases.

2.3.1    Hardware Support Retired in This Release

The following note provides information on hardware support that has been retired in this release of the operating system.

2.3.1.1    Network Adapters

Starting with Tru64 UNIX Version 5.1B , the DETRA Token Ring network adapter for 4 Mbps and 16 Mbps networks is no longer supported.

Most customers have upgraded their Token Ring network infrastructure to standard 100 Mbps Fast Ethernet or 1000 Mbps Gigabit Ethernet networks, rendering the use of Token Ring obsolete. However, there are a variety of vendor solutions which can be used to bridge a Token Ring network to an existing Ethernet network, should this functionality be desired.
