In this video, we’ll explain what the ORA-02291 “parent key not found” error is, see an example, and look at how to resolve it.
This error usually happens when we try to insert data into a table.
It looks like this:
Error is: ORA-02291: integrity constraint (constraint_name) violated – parent key not found
So what does this error mean?
It means we’re trying to insert data into a child table, and there is no related record in the parent table.
If a foreign key has been set up to enforce this relationship, there needs to be a parent to insert a child that refers to it.
Watch the video to see an example of this error as well as how to resolve it.

ORA-08102 & ORA-08103 tips

Question: I am getting an ORA-08102 and ORA-08103 errors.

How do I fix the ORA-08102 and ORA-08103 errors?

Answer: The ORA-08102 and ORA-08103 error is usually caused by an index corruption. The solution is to rebuild the index. If that fails, try to drop and re-create the index.

The oerr utility shows this for the ORA-08102 and ORA-08013 errors:

ORA-08102: index key not found, obj# %s, file %s, block %s (%s)

Cause: Internal error: possible inconsistency in index

Action: Send trace file to your customer support representative, along

with information on reproducing the error

ORA-08103: object no longer exists

Cause: The object has been deleted by another user since the operation began, or a prior incomplete recovery restored the database to a point in time during the deletion of the object.

Action: Delete the object if this is the result of an incomplete recovery.

ORA-08102: index key not found obj# %s, file %s, block %s (%s)

I got ” ORA-08102: index key not found, obj# %s file %s, block %s (%s) ” error in Oracle database.

ORA-08102: index key not found obj# %s, file %s, block %s (%s)

Details of error are as follows.

ORA-08102: index key not found, obj# %s, file %s, block %s (%s) Cause: Internal error: possible inconsistency in index Action: Send trace file to your customer support representative, along with information on reproducing the error

index key not found, obj# %s, file %s, block %s (%s)

This ORA-08102 error is related with the Internal error: possible inconsistency in index.

Send trace file to your customer support representative, along with information on reproducing the error.

The issue is caused by a corrupted index.

Rebuild the corrupted index using the following steps:

C onnect to the database ‘as sysdba’. Identify the affected index by executing the following query: select owner, object_name, subobject_name from DBA_OBJECTS where object_id= ; Rebuild the identified index: alter index rebuild online;

If the Rebuild index don’t solve your error, then drop and recreated the index.

ORA-08102: index key not found, obj# 35775, file 34, block 5830 (2) on a function-based index

ORA-08102 means there is a mismatch between keys (values) stored in an index and values of indexed column in the table.

[oracle@joedb~]$ oerr ora 08102 08102, 00000, “index key not found, obj# %s, file %s, block %s (%s)” // *Cause: Internal error: possible inconsistency in index // *Action: Send trace file to your customer support representative, along // with information on reproducing the error

After an index has been created for a while, some kind of corruption happens which causes either the data in table or index changed — mismatching.

When this happens, the application will get the ORA-08102 errors during accessing the corresponding table(index). You won’t see the error explicitly in the alert.log, but something like:

***************************************************************** 2021-03-18T02:06:22.424310-05:00 Errors in file /opt/oracle/diag/rdbms/prod/PROD/trace/PROD_ora_4611.trc: 2021-03-18T02:06:27.408745-05:00 *****************************************************************

The trace file actually has the information about it like:

oer 8102.2 – obj# , rdba: (afn , blk# )

So searching trace file with the pattern “oer 8102” will tell how many trace files generated during a period for this error. With the information of object#, file#, block# we can easily identify which file and which index has this mismtach:

SQL> select file#, TS#, name, STATUS, enabled from v$datafile where file#=34; SQL> select owner, object_name, object_type from dba_objects where object_id = 35775; SQL> select tablespace_name, segment_type, owner, segment_name from dba_extents where file_id = 34 and 5830 between block_id AND block_id + blocks-1;

DBV might not find anything if you run it against the data file affected unless there is a real block corruption.It is the same for RMAN validate.

[oracle@joedb ]$ dbv file=/dbase/data/PROD/data_ind_115.dbf BLOCKSIZE=8192 DBVERIFY: Release 19.0.0.0.0 – Production on Thu Mar 18 17:04:58 2021 Copyright (c) 1982, 2019, Oracle and/or its affiliates.

Additionally we can run “analyze index/table validate structure” to detect the corruption. Nevertheless, rebuild the index is sufficient if the table is good.

When considering rebuild an index, there are two options,

use rebuild clause with alter index. It’s faster and when using with online clause, the application can still access the index. However, it uses the existing index as the data source. In this case, it might not solve the mismatch. drop the index, then create. It needs to re-scan the table, slower, but will solve the mismatch issue if the underlying table is good.

An important thing here is when the index is a function-based index, double check the index defintion and make sure the function is deterministic, especially for a user defined function which must be declared as DETERMINISTIC and the plsql exception handler should not ignore error ORA-4091. That’s because index keys is based on the returned values of the fucntion used in the index definition.

A deterministic function must return the same value on two distinct invocations if the arguments provided to the two invocations are the same.

Oracle doesn’t verify if a function is DETERMINISTIC when it is declared so. That means whoever writes the function has to make sure the function is actually deterministic, not just declare it is.

Non-deterministic Functional indexes like the ones depending on NLS settings are exposed to ORA-8102.

How to Resolve ORA-08102: index key not found

ORA-08102

Found some ORA-08102 errors during executions of SQL statements like this:

ERROR at line 1:

ORA-08102: index key not found, obj# 98830, file 69, block 120164 (2)

ERROR at line 1:

ORA-08102: index key not found, obj# 98832, file 69, block 120172 (2)

ERROR at line 1:

ORA-08102: index key not found, obj# 98831, file 69, block 120140 (2)

Solutions

index key not found? I suspected that the above indexes has been corrupted logically.

1. Rebuild Indexes

The first solution to ORA-08102 is to rebuild those indexes. First of all, we use those object id to compose rebuild statements like this:

SQL> column stmts format a50;

SQL> select ‘ALTER ‘ || object_type || ‘ ‘ || owner || ‘.’ || object_name || ‘ REBUILD;’ stmt from dba_objects where object_id in (98829, 98830, 98831) and object_type = ‘INDEX’;

STMT

————————————————–

ALTER INDEX ERPAPP.FINNS5S1 REBUILD;

ALTER INDEX ERPAPP.FINNS6S1 REBUILD;

ALTER INDEX ERPAPP.FINNS7S1 REBUILD;

Then we use these statements to rebuild the indexes.

SQL> ALTER INDEX ERPAPP.FINNS5S1 REBUILD;

Index altered.

SQL> ALTER INDEX ERPAPP.FINNS6S1 REBUILD;

Index altered.

SQL> ALTER INDEX ERPAPP.FINNS7S1 REBUILD;

Index altered.

2. Recreate Indexes

Rebuilding problematic indexes should have solved ORA-08102, but in some cases, you have to use DROP then CREATE INDEX instead.

SQL> select ‘DROP INDEX ‘ || b.owner || ‘.’ || b.index_name || ‘;’ || chr(10) || ‘CREATE INDEX ‘ || b.owner || ‘.’ || b.index_name || ‘ ON ‘ || c.table_owner || ‘.’ || c.table_name || ‘ (‘ || c.column_name || ‘) TABLESPACE ‘ || b.tablespace_name || ‘;’ stmt from dba_objects a inner join dba_indexes b on a.object_type = ‘INDEX’ and a.owner = b.owner and a.object_name = b.index_name inner join dba_ind_columns c on b.owner = c.index_owner and b.index_name = c.index_name where a.object_id in (98829, 98830, 98831);

STMT

——————————————————————————–

DROP INDEX ERPAPP.FINNS5S1;

CREATE INDEX ERPAPP.FINNS5S1 ON ERPAPP.FINLOC1S025 (SWITCH_SUM_PH) TABLESPACE FINCCORP;

DROP INDEX ERPAPP.FINNS6S1;

CREATE INDEX ERPAPP.FINN65S1 ON ERPAPP.FINLOEC1S026 (SWITCH_SUM_PH) TABLESPACE FINCCORP;

DROP INDEX ERPAPP.FINNS7S1;

CREATE INDEX ERPAPP.FINNS7S1 ON ERPAPP.FINLN1S027 (SWITCH_SUM_PH) TABLESPACE FINCCORP;

Then execute the above statements.

Block Corruption – ORA-08102: index key not found

Block Corruption – ORA-08102: index key not found

June 1, 2011

We had a refresh job which started failing with the following error:

Error at line 2 ORA – 12008 : error in materialized view refresh path ORA – 08102 : index key not found , obj# 6104122 , file 364 , block 27923 ( 2 ) ORA – 06512 : at “SYS.DBMS_SNAPSHOT” , line 2545 ORA – 06512 : at “SYS.DBMS_SNAPSHOT” , line 2751 ORA – 06512 : at “SYS.DBMS_SNAPSHOT” , line 2720 ORA – 06512 : at line 2

ORA-08102 is a mismatch between the key(s) stored in the index and the values stored in the table.

To resolve i first found out which object was affected:

select owner , object_name , object_type from dba_objects where object_id = 6104122 ;

Which returned the schema.I_MY_OBJECT

This was an index so then the next step was to rebuild the index

ALTER INDEX SCHEMA. I_MY_OBJECT rebuild ;

but this didn’t resolve the error. Research found the following:

Rebuilding index will not work on most (if not in all) cases. Rebuilding index does not visit table at all. It uses existing index structure, to create new segment, so this problem will be transferred to new index as well.

In the end i dropped and recreated the index which seemed to resolve the error.
