If you are familiar with SCO OpenServer, 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 and Getting Started Guide for information.
See ``What are porting, integration, and compatibility?'' for further information about application compatibility.
The tape(1) and tapecntl(1) commands remain, with some changes.
Set the environment variable OSRCMDS=on to use the SCO OpenServer version of cpio or any command. Remember to unset the variable when you have finished restoring the backup. Alternatively, use the full pathname /OpenServer/bin/cpio.
Restore operations can be performed using the cpio utility on the command line. The examples included here assume you are using the standard tape device, /dev/ctape1.
To restore a backup:
cpio -iAmudB -I /dev/ctape1
Restore individual files or directories by adding them to
the end of the command line. Use the full pathname
and omit the leading ``/'', as in this example:
tmp/hold/time
Use the ``'' Bourne shell wildcard character to
restore a directory, as in this example:
tmp/hold/other/
To verify a backup:
cpio -itvn -I /dev/ctape1
To list the files on a backup:
cpio -iABmudq -I /dev/ctape1 \*
This command reads the first file off the media. Backups
created by the SCO OpenServer Backup Manager include a file
list called _BACKUP_CONTENTS_ at the beginning
of each backup. If the backup was created by another means,
use this command to list the files:
cpio -itv -I /dev/ctape1
This means that the system is more responsive to variations in workloads and there is more flexibility in tuning.
memfs is backed by the swap device, with memory usage dynamically adjusted to match demand. By comparison, a RAM disk device cannot utilize swap, nor can it vary its memory usage.
When the system enters multiuser mode, seven multiscreen text login prompts and one graphical login prompt are presented. The traditional SCO OpenServer screen switch sequences can be used to navigate among the multiscreens, with the following exceptions:
If you prefer to have eleven text login prompts as in SCO OpenServer, instead of the default seven, you can run the following script to enable the extra login prompts:
for i in 09 10 11 12 do pmadm -a -p contty -s $i -S login -fu -v `ttyadm -V` \ -m "`ttyadm -d /dev/vt$i -l console -s /usr/bin/shserv \ -p \"Login (vt$i): \"`" done
Note there must be no trailing spaces after the backslash (``\'') characters at the ends of the third and fourth lines.
For more information on using multiscreens see ``Running programs simultaneously with multiscreen displays''.
