what happened between 14.55:07 thursday and 13.51 friday?
my database is gone now? is informix reinitialized automatically?

Please help me

Did you re-start informix with 'oninit -i' ?

This will re-initialize informix and all your data
is lost. You need to start informix with 'oninit',
the '-i' option is only for the first initialization
of the server.
