crash recovery in informix

hi every one, with progress we can recover from system faileres without using a backup medi. in progress we call that a crash recovery.(that suppose that a disk is still ok). My question is : Can we do that in informix ?? I mean, for exemple if we had a problem causing by a long transaction, or a prosses how was updating data was killed and we have "can't attache to the shared memory". can we recover that without using a backup media. and I suppose that my logical logs are backed up to /dev/null thanks for every response !! ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
