查詢：

1.查詢相關段信息

col owner format a10

col object_name format a30

select object_id, data_object_id, owner, object_name, object_type from dba_objects where data_object_id in (8677570, 489718) or object_id in (8677570, 489718);

2.查詢段詳細信息

select * from seg$ where file#=32 and block#=2555025;

3.查詢相關數據文件

col name format a30

select name from v$datafile where file#=32;

4.查詢表空間信息

select * from v$tablespace where ts#=7;

5.查詢相關區信息

select owner,segment_name,partition_name,segment_type,block_id from dba_extents where relative_fno=32 and 2555025 between block_id and block_id+blocks;

select owner,segment_name,partition_name,segment_type,block_id from dba_extents where block_id=;

緣由：

通過MOS查詢分析，該錯誤觸發BUG：19689979 。

該BUG是因爲truncate或者drop一個正在被訪問的表分區致使。

觸發該BUG的對象爲：

SYS@suseora2> select OWNER,SEGMENT_NAME,PARTITION_NAME,SEGMENT_TYPE,BLOCK_ID from DBA_EXTENTS where RELATIVE_FNO=9 and 424849 between BLOCK_ID and BLOCK_ID+BLOCKS;         OWNER                          SEGMENT_NAME                                                                      PARTITION_NAME                 SEGMENT_TYPE         BLOCK_ID ------------------------------ --------------------------------------------------------------------------------- ------------------------------ ------------------ ---------- USDPCENTER                     T_PERSONALLIB                                                                     P42                            TABLE PARTITION        424832

解決方案：

1.當出現問題時flush共享池。

2.修改隱含參數_part_access_version_by_number爲false。（RAC須要將各個節點同時重啓以修改該參數）

目前已經將flush共享池。flush以後沒有發現該報錯。
