从这个时间点来看,应该是数据库启动GATHER_STATS_JOB收集统计信息时发现这个错误。

出现oer 8102.2的错误,有两种可能:1.坏块,2.表和索引数据不一致
3.找出相关对象
SQL> col object_name for a30 SQL> col owner for a10 SQL> select object_name,owner,object_type 2 from dba_objects where object_id=4152; OBJECT_NAME OWNER OBJECT_TYPE ------------------------------ ---------- ------------------- WRI$_SEGADV_OBJLIST_IDX_TS SYS INDEX SQL> select OWNER,TABLE_NAME from dba_indexes 2 where index_name='WRI$_SEGADV_OBJLIST_IDX_TS'; OWNER TABLE_NAME ---------- ------------------------------ SYS WRI$_SEGADV_OBJLIST SQL> ANALYZE TABLE sys.WRI$_SEGADV_OBJLIST VALIDATE STRUCTURE CASCADE; ANALYZE TABLE sys.WRI$_SEGADV_OBJLIST VALIDATE STRUCTURE CASCADE * ERROR at line 1: ORA-01499: table/index cross reference failure - see trace file
4.分析坏块(逻辑/物理)

检测证明,对象以及对象所属的数据文件,无坏块现象
5.分析表和index不一致
--找出index对应列 SQL> SELECT table_name , column_name from dba_ind_columns 2 WHERE index_name='WRI$_SEGADV_OBJLIST_IDX_TS' order by table_name; TABLE_NAME COLUMN_NAME ------------------------------ -------------------- WRI$_SEGADV_OBJLIST TS_ID --确定对应列是否允许为null SQL> desc WRI$_SEGADV_OBJLIST Name Null? Type ----------------------------------------- -------- ---------------------------- AUTO_TASKID NUMBER TS_ID NUMBER OBJN NUMBER OBJD NUMBER STATUS VARCHAR2(40) TASK_ID NUMBER REASON VARCHAR2(40) REASON_VALUE NUMBER CREATION_TIME TIMESTAMP(6) PROC_TASKID NUMBER END_TIME TIMESTAMP(6) SEGMENT_OWNER VARCHAR2(30) SEGMENT_NAME VARCHAR2(81) PARTITION_NAME VARCHAR2(30) SEGMENT_TYPE VARCHAR2(18) TABLESPACE_NAME VARCHAR2(30) --确认在表中对应列是否有空值 SQL> SELECT /*+ FULL(t1) */ count(TS_ID) 2 FROM WRI$_SEGADV_OBJLIST t1 3 WHERE t1.TS_ID IS NULL; COUNT(TS_ID) ------------ 0 --表比index多数据 SQL> SELECT /*+ FULL(t1) */ TS_ID 2 FROM WRI$_SEGADV_OBJLIST t1 3 MINUS 4 SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ TS_ID 5 FROM WRI$_SEGADV_OBJLIST t where ts_id is not null; no rows selected --index中数据条数 SQL> SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ count(TS_ID) 2 FROM WRI$_SEGADV_OBJLIST t 3 where ts_id is not null; COUNT(TS_ID) ------------ 901 --表中数据条数 SQL> SELECT /*+ FULL(t1) */ count(TS_ID) 2 FROM WRI$_SEGADV_OBJLIST t1 ; COUNT(TS_ID) ------------ 937 --index中不同值数量 SQL> SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ 2 COUNT(DISTINCT TS_ID) 3 FROM WRI$_SEGADV_OBJLIST t WHERE TS_ID IS NOT NULL; COUNT(DISTINCTTS_ID) -------------------- 5 --表中不同值数量 SQL> SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ TS_ID 2 FROM WRI$_SEGADV_OBJLIST t WHERE ts_id IS NOT NULL 3 MINUS 4 SELECT /*+ FULL(t1) */ TS_ID 5 FROM WRI$_SEGADV_OBJLIST t1 ; TS_ID ---------- 4 --对比可以知道index中的唯一值比表中,这个也就解释了,为什么表中总条数多, --但是他们两做减法的时候,记录为空 --索引表比表多数据 SQL> SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ TS_ID 2 FROM WRI$_SEGADV_OBJLIST t WHERE ts_id IS NOT NULL 3 MINUS 4 SELECT /*+ FULL(t1) */ TS_ID 5 FROM WRI$_SEGADV_OBJLIST t1 ; TS_ID ---------- 4
上面的检测证明:1.表中有索引中无的数据,2.索引中有表中不存在数据
6.解决问题
SQL> alter index WRI$_SEGADV_OBJLIST_IDX_TS rebuild online; Index altered. --测试index中总条数 SQL> SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ count(TS_ID) 2 FROM WRI$_SEGADV_OBJLIST t 3 where ts_id is not null; COUNT(TS_ID) ------------ 937 --无多余index项(以前唯一值为4的记录已经不存在) SQL> SELECT /*+ index(t WRI$_SEGADV_OBJLIST_IDX_TS) */ TS_ID 2 FROM WRI$_SEGADV_OBJLIST t WHERE ts_id IS NOT NULL 3 MINUS 4 SELECT /*+ FULL(t1) */ TS_ID 5 FROM WRI$_SEGADV_OBJLIST t1 ; no rows selected --通过上述测试,证明表和index不一致问题解决
