SCO Support Level Supplements

The following SCO Supplements have been updated or are new and may be required on SCO Xenix or SCO Unix systems.
LNG305 Brings the SCO 3.2 v2 Development system up to X/Open Portability Guide 3 standard.
UNX249 Unix Printer supplement (revision C) includes support for print filters.
UNX304 Brings the SCO 3.2 v2 Operating System up to X/Open Portability Guide 3 standard.
XNX296 Xenix maintenance supplement for version 2.3.(012) to update them to 2.3.3. This fix supersedes XNX155. Support for multi-volume cpio and other useful additions.
XNX330 Corrects problems with multiple user logins on MCA Xenix 2.3.4 (replacement N1 disk, containing new /etc/getty.)
XNX339 Xenix System Services includes patches for the handling of DMA 3 correctly, potential kernel panics with cards using interrupts above 7, correction of file system inconsistencies and shared memory fixes.

Recommendations

Unix Support recommend that XNX330 is installed on all MCA Xenix 2.3.4 systems. XNX339 should be installed on all Xenix revisions from 2.3.2 to 2.3.4 on both AT and MCA buses. XNX296 includes support for multiple volume cpio backups which is increasingly useful given the large quantity of data now being stored.

The preferred backup mechanism on both Xenix and Unix remains cpio which allows full system backups to be taken unlike the tar utility. Please remember all backups must be verified, it is not sufficient to say because the backup worked the data is safe.

Example backup scripts are available from Unix support via the Unix front end server electronic mail connection.
