>Learned the new thing today.

few days ago our DBA team encountered yet another flashback issue. You have to have nologging on some db tables. You recover your database.
You truncate those nologging tables which are staging/temporary tables anyway.
And then you get
ORA-1578: ORACLE data block corrupted
Then you find that metalink note "Cannot Reuse a Corrupt Block in Flashback Mode, ORA-1578 [ID 729433.1]" claims this is fixed in 11.1 but 10g are all affected.

That one was a good point to demonstrate what good comes out of using new features recklessly.

Thanks, John, I checked out our log and email back the date the flashback log had been stopped. It was exactly the case that our flashback area was 100% full. Until now, I donít know it automatically disable the flashback. Learned the new thing today. Thanks again.

Joan

Hi Listers,

I had set flashback on to both our primary and standby databases since it was setup. I just noticed that it was disabled a year ago. I couldnít recall that I had issued any alter database command in the database. Is there any possible causes could turn the flashback_on =off?

Thanks,

Joan
