Fred,

f> Statement failed, SQLCODE = -901

f> Lock conflict on no wait transaction
f> -database mbtdw.gdb shutdown

weird. It looks like the database in in shutdown mode (which would
explain why only SYSDBA and its creator can access it), but I can't
say why. Perhaps your cron job shuts the database down before backing
it up?

Anyway, you can try to manually bring it back online with gfix -online.

Ciao
