Récupération manuelle et correction de la base de données Oracle
Fournir une solution Oracle bug fix
Ce qui peut être récupéré
En-tête / métadonnées de disque ASM diskgroup corrompu, ASM diskgroup ne peut pas être monté
Restaurations incohérentes / récupérations ou toute situation empêchant votre datase d'ouvrir, comme manquant archivelogs
Incompatibilité des sauvegardes dues à une rotation défectueuse de la bande
Corruption des dictionnaires de données ou des objets bootstrap
La perte de tablespace système: dans le cas d'un dictionnaire de données manquant, un scanner heuristique examinera les données et tentera de déterminer les types de données et les colonnes
Fichiers de données orphelins: identique à la perte du tablespace système, même si vous n'avez qu'un seul fichier de données - les données peuvent être extraites
Tablespaces supprimés: si les fichiers de données existent toujours, les données peuvent être récupérées
Les tables perdues: geler l'application / base de données et faire une copie du ou des fichier (s) affecté (s) immédiatement pour améliorer les chances de récupération
Tables tronquées: est fondamentalement la même que les tables perdues
Colonnes tombées
En bref, si les données sont encore sur les médias, nous pouvons le récupérer.

| 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 |

| 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). |

| 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; |

| 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. |
