查询：
1. 查询相关段信息
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. 查询段详细信息
select * from seg$ where file#=32 and block#=2555025;
3. 查询相关数据文件
col name format a30
select name from v$datafile where file#=32;
4. 查询表空间信息
select * from v$tablespace where ts#=7;
5. 查询相关区信息
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=;
原因：
经过 MOS 查询分析，该错误触发 BUG：19689979。
该 BUG 是由于 truncate 或者 drop 一个正在被访问的表分区导致。
触发该 BUG 的对象为：
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
解决方案：
1. 当出现问题时 flush 共享池。
2. 修改隐含参数 _part_access_version_by_number 为 false。（RAC 需要将各个节点同时重启以修改该参数）
目前已经将 flush 共享池。flush 之后没有发现该报错。
