Regenerate the sysutils database
If you lose the sysutils database, use the bldutil utility in $INFORMIXDIR/etc on UNIX™ or %INFORMIXDIR%\etc on Windows™ to recreate the sysutils database with empty tables.
Then use the onsmsync utility
to recreate the backup and restore data in sysutils.
Restriction: If both the sysutils database and emergency
boot file are missing, you cannot regenerate them with onsmsync.
Be sure to back up the emergency boot file with your other operating-system
files.
