ORA-08103: 現在、指定したオブジェクトは存在しません

 

ORA-08103エラの診断は8103エラのERROR STACK TRACEを作成する必要がある。TRACEで8103オブジェクトを引き起こした具体的なOBJとOBJDを記録する・これはcorruptionを含むかもしれないオブジェクトをより容易く探し出せる。けどフォアグラウンドプロセスがORA-08103になるから、バックグラウンドでTRACEファイルを作成しない、これは8103を設定し、ERRORSTACKのEVENTS引き起こす必要がある:

 

ALTER SYSTEM SET  EVENTS  ‘ 8103 TRACE NAME ERRORSTACK LEVEL 3’;

解決策は:
1. OBJDとDBAで具体的なテーブル名とブロック番号を探し出す

  1. できればそのテーブルをanalyze .. validate structureしてください
    3. できればそのテーブルを含むtablespaceに対して dbms_space_admin.ASSM_TABLESPACE_VERIFYしてください
    4. できればそのテーブルあるいは関するパーティションを移して、このトラブルを避けてみてください
    5. できればそのテーブルあるいはパーティションをMSSMテーブルスペースに移して、このトラブルを避けられる

execute dbms_space_admin.tablespace_verify(‘&tablespace_name’)
oradebug setmypid
oradebug tracefile_name

 

execute dbms_space_admin.assm_tablespace_verify(‘&tablespace_name’,dbms_space_admin.TS_VERIFY_BITMAPS)
oradebug setmypid
oradebug tracefile_name

After increase in load, queries against ASSM table intermittently fail with ORA-8103 when executed in

parallel if there are concurrent updates performed on the table.

 

This appears to only manifest when access is in parallel.

 

Cause

 

This is caused by Bug 5637976 ORA-8103 EVEN WITH THE WORKAROUND FROM Bug 3569503 fixed in 11.1g.

 

Concurrent inserts and direct path exports on an ASSM table causes ORA-8103/ORA-1410.

This is due to the fact that newly formatted blocks between low and high water mark do not get flushed to disk and query sees old copies from disk.

 

Rediscovery Information:

  1. Concurrent inserts and exports on ASSM tables
  2. ORA-8103/ORA-1410
  3. redo dump shows ‘ktspbfredo – Format Pagetable Datablock’ for that rdba

Note= OERR: ORA-8103 “object no longer exists” / Troubleshooting, Diagnostic and Solution (Doc ID 8103.1)

==>

Cause

ORA-8103 is caused by an invalid block type. The block header has an invalid block type or the

block type inside the block is not expected; e.g. a data block (Type=6) was expected but the

actual block information is not a data block (Type!=6).

 

ORA-8103 is also caused by an unexpected data_object_id where it is changing for the involved

objects while the affected SQL statement is executed.
