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:

  1. Connect to the database ‘as sysdba’.
  2. Identify the affected index by executing the following query:
    select owner, object_name, subobject_name from DBA_OBJECTS where object_id=<object# reported in the original error>;
  3. Rebuild the identified index:
    alter index <object_name returned from the query in Step 2> rebuild online;

 

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