ORA-08103: object no longer exists tips
Oracle Error Tips by Stephanie F.
Question: I am getting
the ORA-08103 error when trying to create an index.
How do I fix the ORA-08103 error?
The Oracle docs note this on the
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: Remove references to the object or delete
the object if this is the result of an incomplete recovery.
show that there are many bugs associated with ORA-08103. A description of
the error per the documents is as follows:
This error can occur, if the header block
has an invalid block type or data_object_id (seg/obj) stored in the
block is different than the data_object_id stored in the segment
header. This error can be treated as a block corruption.
There are several likely reasons for this error, and you
should always check your alert log for details. This error often requires
opening a service request with MOSC:
0: A software bug (see list below).
1: You are not signed-on as the table owner.
2: Database corruption of a header block.
delete of the target table. (check the recyclebin)
4: Data file I/O error (check alert log)
5: corruption in UNDO log (drop and re-create)
6. An index is disabled or is offline.
Possible solution include:
1: Set db_file_multiblock_read_count to 1.
2: Run dbv on all data files.
3: Run catalog.sql,
catproc.sql and utlrp.sql to ensure no data dictionary corruption.
4: Purge recyclebin & dba_recyclebin.
5: When the ORA-08103 is on an index operation, place the
index online or make index usable
select index_name , status from user_indexes;
alter index idx_cust rebuild online;
Bugs and ORA-08103
Below are the twelve bugs which contain
ORA-08103 in Oracle Enterprise Edition; version 11g
13618170 ORA-8103 for create index online
- Bug 5523799
Abstract: Various OERI (eg kcbgtcr_12) using ASSM
Versions affected: 126.96.36.199 & 10.1.0.5
Fixed in version: 10.1.0.6
Operations such as
TRUNCATE on ASSM segments can lead to
subsequent ORA-600 kcb* errors such as ORA-600 [kcbnew_3], ORA-600
[kcbgtcr_3], ORA-600 [kcbgtcr_12]
This problem is introduced in the 188.8.131.52 and 10.1.0.5 patch sets by the
fix for bug 3279497
Operations such as TRUNCATE on ASSM segments can lead to
subsequent ORA-600 kcb* errors such as ORA-600 [kcbnew_3],
ORA-600 [kcbgtcr_3], ORA-600 [kcbgtcr_12] .
TRUNCATE operations on ASSM managed segments, or use
TRUNCATE with a KEEP STORAGE option. Once the issue has
occurred then the problem is that there is a CURRENT block image in the
cache which should not be there. In 10g flush the buffer cache to remove
the problem block image/s from the cache. (In 9.2 there is no SQL to
flush the buffer cache)
One-off patch available for few platforms on top of 184.108.40.206 & 10.1.0.5
Check the MOSC for Patch 5523799 availability.
