Differences for UnixWare 2 and SCO OpenServer users

Differences for UnixWare 2 users

If you are familiar with UnixWare 2, note the following differences in UnixWare in addition to the new features listed in ``Release 7.0.0 new features'':

Software management
See the Getting Started Guide for installation information.

Application compatibility
If you are using the Panorama Desktop, UnixWare 2 compiled X applications will often fail because LD_LIBRARY_PATH is not defined when the desktop comes up. (It is defined for the UnixWare Desktop). Type the following command:

LD_LIBRARY_PATH=:/usr/X11R6.1/lib export LD_LIBRARY_PATH

This should allow the binary to get past the loading of the dynamic libraries.

See ``What are porting, integration, and compatibility?'' for information about application compatibility.

Installation is substantially improved.

See the Getting Started Guide and Getting Started Guide for information.

System administration and SCOadmin

Single network administration tool
A single network administration tool, the Network Configuration Manager, with its own online help system, lets you configure and manage network connections, network adapters, and WANs via the netcfg(1M) utility. You can still view network device information in dcu(1M), which you can access only via the console in this release.

netcfg autodetects PCI and ISA network and graphics adapters and configures MDI, DLPI and ODI drivers.

Hardware autodetection
UnixWare uses dcu(1M), a driver-independent autoconfiguration subsystem, for hardware autodetection.

In general, EISA, MCA, and PCI devices are autodetected, whereas ISA devices whose configuration differs from their entry in the System file will not be detected unless you enter configuration information via dcu. An exception to this rule is that ISA network and graphic adapters are autodetected via driver probes.

mosy compiler
The mosy(1Msnmp) compiler is shipped with the base operating system.

Administration commands
All PDI commands have been renamed to have an ``sdi'' prefix. Links to the original name have been maintained. Other commands, for example, tapecntl(1), tape(1), edvtoc(1M), prtvtoc(1M), and diskadd(1M), remain.

Point-to-point remote administration
Most managers have point-to-point remote administration capabilities available from the Open Host menu option.

NetWare administration
NetWare administration is now available under SCOadmin. See ``SCOadmin managers'' for full details.

Third-party management and configuration utilities
Third-party utilities such as RAID configuration and monitoring utilities have not been tested and are not guaranteed to be compatible with UnixWare.

System backup
ARCserveIT from Computer Associates provides the interface for backup and restore.

Tape backup
You can restore a tape backup on UnixWare provided the backup application, the tape media and the tape mode used to create the backup are all compatible with UnixWare.

crash(1M) command
Expression parsing is enhanced in crash(1M).

dump(1) command
Error handling is enhanced in dump(1).

Core operating system
The core operating system has developed substantially during previous releases of UnixWare. The following differences exist between UnixWare 2 and UnixWare:


Mail and messaging


Base drivers


Network hardware support

X-server and graphics hardware support

RFC 1122/1123 (Internet hosts: communication layer and application layer and support) is supported.

SCOhelp and X11 clients
A browser based on Netscape Navigator(TM) 3.0 is provided. Dynatext is not available.

Visual Tcl

Console Multiscreens
See the keyboard(7) manual page for details of screen switch sequences. Users who prefer to use vtlmgr(1) and newvt(1) instead of multiscreens can still continue to do so. The default configuration described above uses virtual terminals 00 through 08. The first free virtual terminal available is therefore 09. To return the console to the traditional UnixWare configuration without text login prompts, run the following command:

sacadm -d -p contty

The login prompts can be subsequently re-enabled by running the following command:

sacadm -e -p contty

For more information on using multiscreens see ``Running programs simultaneously with multiscreen displays''.

Documentation is shipped as HTML and may be read with any world wide web browser. It is organized as topics, rather than as books.
