PURPOSE

This article provides information about error ORA-1578 and possible actions.

SCOPE

This note is intended for general audience as initial starting point for beginning diagnosis of ORA-1578.

DETAILS

Error:  ORA-01578 (ORA-1578)
Text:   ORACLE data block corrupted (file # %s, block # %s)
Cause:  The data block indicated was corrupted, mostly due to software errors.
Action: Try to restore the segment containing the block indicated. This
may involve dropping the segment and recreating it. If there
is a trace file, report the errors in it to your ORACLE
representative.

 

Description

Error ORA-1578 reports a Physical Corruption within a block or a block marked as software corrupt.  Reference Note 840978.1 for Physical Corruption concept.

ORA-1578 – Solution (excludes NOLOGGING case)

  • Main article describing corruption issues in different Oracle areas and Solutions:
Note 28814.1 Handling Oracle Block Corruptions in Oracle7/8/8i/9i/10g

Database in ARCHIVELOG mode

    • Repair the Block with RMAN Block Media recovery.  In order to repair a block causing ORA-1578 with Block Media Recovery, the database must be in archivelog mode.
Note 144911.1 RMAN : Block-Level Media Recovery – Concept & Example

Note 342972.1 How to perform Block Media Recovery (BMR) when backups are not taken by RMAN

Database in NOARCHIVELOG mode or there is not a valid backup:

    • Identify the segment producing ORA-1578:
NOTE 819533.1 How to identify the corrupt Object reported by ORA-1578 / RMAN / DBVERIFY

NOTE 472231.1 How to identify all the Corrupted Objects in the Database reported by RMAN

NOTE 836658.1 Identify the corruption extension using RMAN/DBV/ANALYZE etc. Main sections in Note 836658.1 to identify corrupt blocks causing ORA-1578 are:

RMAN – Identify Datafile Block Corruptions
DBVerify – Identify Datafile Block Corruptions

    • For INDEX segment type consider to recreate the index.
    • Drop the segment and recover it from a different source.  Or use the next options to recover the information from the current segment:
    • For TABLES the corrupt block can be skipped using DBMS_REPAIR and decide to create a new table using “Create Table As Select”:
Note 556733.1 DBMS_REPAIR script
Note 68013.1 DBMS_REPAIR example
    • A Datapump export with ACCESS_METHOD=DIRECT_PATH (default value) may also be used to skip the corrupt block, then the table may be truncated or dropped and imported.
    • Another option is to MOVE the table with “ALTER TABLE MOVE &TABLE_NAME” as the MOVE skips corrupt blocks causing ORA-1578; it is recommended to take a backup (e.g. datapump export before moving the table it).
    • Reference Note 28814.1 for additional cases.

ORA-1578 / ORA-26040 due to NOLOGGING

Error ORA-1578 can also be produced along with error ORA-26040 meaning that the block is corrupt due to a NOLOGGING operation after a recovery.

ORA-1578 / ORA-26040 due to NOLOGGING – SOLUTION

  • Reference the next article to fix error ORA-1578 caused by NOLOGGING:
Note 794505.1 ORA-1578 / ORA-26040 Corrupt blocks by NOLOGGING – Error explanation and solution

ORA-1578 due to incorrect wallet in encrypted database

  • Reference the next article for ORA-1578 caused by incorrect wallet:
Note 1329437.1 ORA-1578 Corrupt Block Found in Encrypted Database

 

Known Corruption issues caused by 3rd party Software Provider

  • Reference the next document for 3rd party known issues causing corruption:
