corrupted datafile - no entries inV$DATABASE_BLOCK_CORRUPTION

user5716448Sep 18 2019 — edited Sep 19 2019

Hi,

Have 10.2.0.2. database and got corruption message when tried to write to a table and other users tried reading table and getting corrupt message.

Message below.

ORA-01115: IO error reading block from file 107 (block # 3984674)

ORA-01110: data file 107: '/<vol>/filename3.dbf'

ORA-27091: unable to queue I/O

ORA-27072: File I/O error

SVR4 Error: 5: I/O error

Additional information: 4

Additional information: 3984673

Additional information: -1

dba team are recovering database to standby database but may take days.

Curious as to if could identify blocks which corrupt and create table on non-corrupt blocks on diff volume

1)

First step would have been to identify corrupt blocks by looking at

but no rows in V$DATABASE_BLOCK_CORRUPTION - any idea why?

How could we find the corrupt blocks?

Also it it possible to create new table ignoring the corrupt blocks?

Also is there a way of identifying the rows which are causing the corruption.

large table using several datafiles.

Thanks
