ORA-01578: ORACLE data block corrupted (file # 7, block # 27489)
ORA-01110: data file 7: ‘/u01/app/oracle/oradata/TESTDB/datafile/o1_mf_kyc_acc_dlzsz7mt_.dbf‘
01578. 00000 - "ORACLE data block corrupted (file # %s, block # %s)"
*Cause: The data block indicated was corrupt. This was a physical
corruption, also called a media corruption. The cause is unknown
but is most likely external to the database. If ORA-26040 is also
signaled, the corruption is due to NOLOGGING or UNRECOVERABLE
operations.
*Action: The general method to repair a media corrupt block is to restore
a backup and recover the backup. For databases in ARCHIVELOG
mode, use block media recovery or media recovery. In some situations,
you can also drop the segment and re-create it. For example, you can
drop an index and re-create the index.
