Another thought on backups...
If you have PMC, do not forget about the "always attached" device.  It will
have the lock on SYSCTL - for those users that do not use a MAPICS backup
and are relying on a non-sys backup, you may not have a save of this file.
It happened to us and we only found out after a disk crash.

I have a pre-backup command that ends jobs with a lock on sysctl and cleans
up abend records
in jobact. I formerly used a post backup command to back up the remaining
libraries on mmlist
but found this was keeping MAPICS dedicated that much longer. I changed the
end of tape
option to 2 (leave) and now I run that command through the OS/400 job
scheduler. These
remaining libraries are being backed up with the save-while-active option
and MAPICS is now
dedicated for only 30 minutes per day. (The Magstar 3570 also cut our backup
time
dramatically)
