$dbv file=/u01/app/oracle/users01.dbfWhen I issued that command the screen started scrolling with a number of messages. Here is a sample message:
Page 12798 is marked corrupt *** Corrupt block relative dba: 0x000031fe (file 0, block 12798) Completely zero block found during dbv:After that, when the dbverify utility had done its job, there was the following message:

Please explain it to me in detail. I would really appreciate it.
I would restore this datafile from a backup. If you are not running archivelog mode, then you'll have to restore...
the entire database. If you are running archivelog mode and have all of the archived transaction logs since this backup was taken, then you can recover up to the current point in time.
