Error Description Corruption related to:
ORA-1578 ORA-1578 is reported when a block is thought to be corrupt on read.

Block

  OERR: ORA-1578 “ORACLE data block corrupted (file # %s, block # %s)” Master Note  
  OERR: ORA-1578 “ORACLE data block corrupted (file # %s, block # %s)”

  Diagnosing and Resolving 1578 reported on a Local Index of a Partitioned table  
ORA-1410 This error is raised when an operation refers to a ROWID in a table for which there is no such row.
The reference to a ROWID may be implicit from a WHERE CURRENT OF clause or directly from a WHERE ROWID=… clause.
ORA 1410 indicates the ROWID is for a BLOCK that is not part of this table.

Row

  Understanding The ORA-1410  
  Summary Of Bugs Containing ORA 1410  
  OERR: ORA 1410 “invalid ROWID”  
ORA-8103 The object has been deleted by another user since the operation began.
If the error is reproducible, following may be the reasons:-
a.) The header block has an invalid block type.
b.) The data_object_id (seg/obj) stored in the block is different than the data_object_id stored in the segment header. See dba_objects.data_object_id and compare it to the decimal value stored in the block (field seg/obj).

Block

  ORA-8103 Troubleshooting, Diagnostic and Solution  
  OERR: ORA-8103 “object no longer exists” / Troubleshooting, Diagnostic and Solution  
ORA-8102 An ORA-08102 indicates that there is a mismatch between the key(s) stored in the index and the values stored in the table. What typically happens is the index is built and at some future time, some type of corruption occurs, either in the table or index, to cause the mismatch.

Index

  OERR ORA-8102 “index key not found, obj# %s, file %s, block %s (%s)  
ORA-1499 An error occurred when validating an index or a table using the ANALYZE command.
One or more entries does not point to the appropriate cross-reference.

Index

  ORA-1499. Table/Index row count mismatch  
  OERR: ORA-1499 table/Index Cross Reference Failure – see trace file  
ORA-1498 Generally this is a result of an ANALYZE … VALIDATE … command.
This error generally manifests itself when there is inconsistency in the data/Index block. Some of the block check errors that may be found:-
a.) Row locked by a non-existent transaction
b.) The amount of space used is not equal to block size
c.) Transaction header lock count mismatch.
While support are processing the tracefile it may be worth the re-running the ANALYZE after restarting the database to help show if the corruption is consistent or if it ‘moves’.
Send the tracefile to support for analysis.
If the ANALYZE was against an index you should check the whole object. Eg: Find the tablename and execute:
ANALYZE TABLE xxx VALIDATE STRUCTURE CASCADE;
Block
  OERR: ORA 1498 “block check failure – see trace file”  
ORA-26040 Trying to access data in block that was loaded without redo generation using the NOLOGGING/UNRECOVERABLE option.

ORA-600[12700] Oracle is trying to access a row using its ROWID, which has been obtained from an index.
A mismatch was found between the index rowid and the data block it is pointing to. The rowid points to a non-existent row in the data block. The corruption can be in data and/or index blocks.
ORA-600 [12700] can also be reported due to a consistent read (CR) problem.

  ORA-600 [12700] “Index entry Points to Missing ROWID”  
ORA-600[3020] This is called a ‘STUCK RECOVERY’.
There is an inconsistency between the information stored in the redo and the information stored in a database block being recovered.

ORA-600[4194] A mismatch has been detected between Redo records and rollback (Undo) records.
We are validating the Undo record number relating to the change being applied against the maximum undo record number recorded in the undo block.
This error is reported when the validation fails.

ORA-600[4137] While backing out an undo record (i.e. at the time of rollback) we found a transaction id mis-match indicating either a corruption in the rollback segment or corruption in an object which the rollback segment is trying to apply undo records on.
This would indicate a corrupted rollback segment.
Undo/Redo
  ORA-600 [4137] “XID in Undo and Redo Does Not Match”  
ORA-600[6101] Not enough free space was found when inserting a row into an index leaf block during the application of undo. Index

ORA-600[4512] Oracle is checking the status of transaction locks within a block.
If the lock number is greater than the number of lock entries, ORA-600 [4512] is reported followed by a stack trace, process state and block dump.
This error possibly indicates a block corruption.
Block
  ORA-600 [4512] “Lock count mismatch”  
ORA-600[2662] A data block SCN is ahead of the current SCN.
The ORA-600 [2662] occurs when an SCN is compared to the dependent SCN stored in a UGA variable.
If the SCN is less than the dependent SCN then we signal the ORA-600 [2662] internal error.
Block
  ORA-600 [2662] “Block SCN is ahead of Current SCN”  
  ORA 600 [2662] DURING STARTUP  
ORA-600[4097] We are accessing a rollback segment header to see if a transaction has been committed.
However, the xid given is in the future of the transaction table.
This could be due to a rollback segment corruption issue OR you might be hitting the following known problem.
Undo
  ORA-600 [4097] “Corruption”  
ORA-600[4000] It means that Oracle has tried to find an undo segment number in the dictionary cache and failed. Undo
  ORA-600 [4000] “trying to get dba of undo segment header block from usn”  
ORA-600[6006] Oracle is undoing an index leaf key operation. If the key is not found, ORA-00600 [6006] is logged.
ORA-600[6006] is usually caused by a media corruption problem related to either a lost write to disk or a corruption on disk.
