Home -> Community -> Usenet -> c.d.o.server -> Re: unrecoverable_time column in v$datafile not being refreshed
Does the unrecoverable_change# get updated, or does it behave the same way ?
Personally I would expect the manual to be wrong. What good does it do you to know when the LAST unrecoverable event occurred ? Surely you need to know when the FIRST one occurred ? After all, if the file goes unrecoverable after 11:00 because of a direct load, it is still notionally unrecoverable after 11:00 even if you do another direct load at 12:00.
Must be another case of the left hand tower not talking to the right hand tower at Redwood.
