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'':
See the Getting Started Guide for installation information.
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

Installation is substantially improved.

A single network administration tool, the

with its own online help system, lets you
configure and manage network connections, network adapters,
and WANs via the

compiler is shipped with the base operating system.
All PDI commands have been renamed to have an ``sdi''
prefix. Links to the original name have been maintained. Other commands,
Point-to-point remote administration
Most managers have point-to-point remote administration capabilities
available from the Open Host menu option.
NetWare administration is now available under SCOadmin. See
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.
ARCserveIT from Computer Associates
provides the interface for backup and restore.
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.
Expression parsing is enhanced in
Error handling is enhanced in
Core operating system
The core operating system has developed substantially during previous releases
of UnixWare. The following differences exist between UnixWare 2 and UnixWare:
The operating system can be booted from alternative disks or partitions.
Limited PCMCIA support is still available as in SCO UnixWare 2.1.
Multi-processor support is limited to the following:
The S5 filesystem is the only SCO OpenServer filesystem that UnixWare supports.
The native SCO OpenServer filesystems
AFS, EAFS and HTFS are not supported.
SCO OpenServer specific filesystem commands are not supported.
Tunables differ as follows:
for full details of tunable parameters.
The tunable parameter PSE_PHYSMEM has been replaced by
The tunable parameters PHYSTOKVMEM,
MAXPMEM, LGDMA_RATIO, and PSE_VMEMSIZE
have been removed.
LOTSFREEBYTES, DESFREEBYTES, MINFREEBYTES,
and PAGEOUTRATE are now autotuned.
Various resource limits have been increased.
The system no longer prompts you for a remote X session when logging
in from an X-terminal, for example, when coming in over telnet.
You now need to use /usr/dt/bin/Xsession. Consequently,
all X-terminals should be configured for XDM if appropriate.
The XDM commands (for example, start_glogin,
have been replaced by scologin.
The xterm windows (the default terminal windows under the
Panorama or Failsafe desktop sessions) function as standard X11R6
xterms, even when the system is installed with a two button mouse.
In particular, the edit menu does not come up from the right
button, nor will <Ctrl><Alt>Button1 paste text. There are two
alternates available: use <Shift><Ins> to paste, or use dtterm
(the default terminal window under the CDE desktop).
Virtual terminals 2 through 8 are now automatically created at multi-user
initialization time, and come equipped with login sessions.
Mail and messaging
mailsurr is not supported.
The MHS gateway is not supported.
sendmail is the default Mail Transport Agent.
/bin/mail is now equivalent to
is compatible with MMDF's rcvtrip.
HP Network printers are supported.
Users can control remotely submitted print jobs.
NetWare Services have been upgraded to version 4.10a. This consists
of both client and server software. Features include:
NetWare IP (IPX tunnelled over IP)
IPX/SPX is configurable with
Network Configuration Manager,
Long password support is available.
The serial driver supports up to 115.2kbps.
Pseudo tty connections are supported.
The FTP application library (libftp) is available.
Network hardware support
The separate configuration utilities for protocol stacks and network
cards in previous UnixWare releases have been replaced by the
Network Configuration Manager,
a single-point, SCOadmin-based network
configuration tool. The Network Configuration Manager provides
online help, automatic device detection, and a facility to test the
operation of configured network adapters.
The UnixWare network driver architecture is based on
(MAC Driver Interface), a modular STREAMS-based interface.
Existing legacy ODI
and DLPI-compliant drivers from third-parties which run on
UnixWare 2 are also compatible with this release.
The network driver statistics utility
information in several views for each configured network adapter.
Cards and drivers can be restarted while maintaining connections.
Online help is available for network adapter configuration in both
character-based and graphical mode.
X-server and graphics hardware support
Drawing requests from an X-client are completed even when the user
has switched to an ASCII console screen.
Adobe TrueType conversion is not provided.
Selected graphics controllers from Chips and Technologies, based on laptop
graphics hardware, are supported. See the
Compatible Hardware Web Page
(or the static version on your product CD-ROM).
RFC 1122/1123 (Internet hosts: communication layer and application
layer and support) is supported.
SCOhelp and X11 clients
A browser based on Netscape Navigator 3.0 is provided. Dynatext is not
The Tcl base has been upgraded from Tcl7.3 to Tcl7.6.
The new base includes added event handling, timers, and socket
support to the Tcl core.
Additional VTcl capability includes:
The ability to run servers standalone from the command line
Optional support for socket connections between the interpreter and server
Help system suppression
ValueString specification on some widgets provided as widget value
(as callbacks or queries)
Support for widgets values provided directly into a Tcl variable
Multi-option GetValue on a single widget

who prefer to use
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
