ORA-08102的处理

来源:互联网 发布:战舰世界乌达洛伊数据 编辑:程序博客网 时间:2024/05/18 02:49

如图,执行存储过程报错

ORA-08102: index key not found, obj# 304067, dba 33580767 (2)

oerr ora 8102
08102, 00000, "index key not found, obj# %s, dba %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
错误信息的意思似乎是需要重新建立索引。

SQL> SELECT owner, object_name, object_type
  2        FROM Dba_Objects
  3       WHERE object_id IN (304067);

OWNER                          OBJECT_NAME                                                                      OBJECT_TYPE
------------------------------ -------------------------------------------------------------------------------- ------------------
SHARE001                       IDX_SHARE_TMP_IPID                                                               INDEX

SQL>alter index share001.IDX_SHARE_TMP_IPID rebuild online;
问题解决!


别人解决此问题的方法:

应用报错:SQLERRM =ORA-08102: index key not found, obj# 255136, dba 3137557995 (2)
经过analyze table t validate structure cascade;验证表和索引的完整性。在udump产生一个trace文件。

  *** SESSION ID:(570.35812) 2006-01-01 10:49:34.095

  同时在trace文件中列出了和表数据不一致的索引项。 如上黑体字部分应该是Oracle验证的正确的表数据的索引项格式。

  而我在该trace文件的Block dump部分却没有找到对应的索引条目。且index block dump中的格式(如下)明显不匹配索引的定义。

  tab 0, row 0, @0x41e
  tl: 102 fb: --H-FL-- lb: 0x0 cc: 19
  col 0: [10] 30 30 30 65 74 64 41 37 31 57
  col 1: [ 4] 38 34 30 20
  col 2: [ 4] 38 34 30 20
  col 3: [12] 39 32 39 31 35 36 30 30 20 20 20 20
  col 4: [ 4] 4d 52 50 59
  col 5: [ 1] 42
  col 6: [10] 30 30 30 31 77 79 4e 54 57 77
  col 7: [ 3] 45 55 52
  col 8: [ 1] 80
  col 9: [ 1] 80
  col 10: [ 1] 80
  col 11: [ 1] 80
  col 12: [ 7] 78 69 0c 1f 18 3c 01
  col 13: *NULL*
  col 14: [10] 2e 31 30 34 38 34 35 32 31 38
  col 15: [10] 2e 31 30 34 38 34 35 31 30 34
  col 16: *NULL*
  col 17: *NULL*
  col 18: [ 1] 80

  该索引建立在9列上。而index block dump显示的却是18列。 经过检查,该索引为compress的;怀疑compress导致索引不一致。查metalink,也发现很多与compress index相关的bug.

  然后删除/重新建立非压缩索引(或者rebuild online;rebuild可能会读取原先的索引段而不会去读表),查询成功,错误消失。
