通过上述分析,可以确定是由于CON$和I_CON2数据不一致,而且是index的数据比表中多了62条.针对这样情况,考虑通过重建index来解决.

因为是数据库核心index,无法直接rebuild解决,只能通过bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决 方式解决

标题:bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决

作者:惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

在Oracle使用的过程中,经常遭遇一些核心index出现异常,导致数据库无法正常使用,特别是在数据库open的情况下,因为出现这些bootstrap$中的部分index是无法通过设置event38003进行重建,从而导致数据库无法正常使用,最常见异常index 有:I_ICOL1, I_TS1, I_CDEF1, I_CDEF2, I_CDEF3, I_CDEF4, I_PROXY_DATA$, I_IND1, I_TS#, I_UNDO1, I_UNDO2, I_COBJ#, I_USER1, I_USER2, I_CON1, I_CON2, I_FILE1, I_FILE2, I_FILE#_BLOCK#, I_USER#, I_OBJ#, I_PROXY_ROLE_DATA$_1, I_PROXY_ROLE_DATA$_2, I_CCOL1, I_CCOL2, I_TAB1, I_COL1, I_COL2, I_COL3, I_OBJ1, I_OBJ2, I_OBJ3, I_OBJ4, I_OBJ5
重建的index异常报错有:ORA-00701,ORA-01410,ORA-08102,ORA-08103,ORA-01578,ORA-01499,ORA-00600等各类错误
因为处理细节复杂,无法一一描述出来.这里假设Oracle数据库一个非常核心的表OBJ$中的I_OBJ1异常,现在准备重建它,大概步骤如下:
1. 假设异常index信息(I_OBJ1)

SQL> alter index sys.i_obj1 rebuild;
alter index sys.i_obj1 rebuild
*
ERROR at line 1:
ORA-00701: object necessary for warmstarting database cannot be altered
SQL> SELECT SQL_TEXT FROM BOOTSTRAP$ WHERE SQL_TEXT LIKE '%obj%';
SQL_TEXT

TINCREASE 0 OBJNO 36 EXTENTS (FILE 1 BLOCK 336))

2. 创建获取异常index所属表

SQL>  select table_name from dba_indexes where owner='SYS' AND INDEX_NAME='I_OBJ1';
TABLE_NAME
--------------------------------------------------------------------------------
OBJ$

3. 获取obj$ ddl 语句

SQL> set long 10000
SQL> set pages 1000
SQL>  SELECT DBMS_METADATA.GET_DDL('TABLE','OBJ$','SYS') FROM DUAL;
DBMS_METADATA.GET_DDL('TABLE','OBJ$','SYS')

  BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)

4. 获取obj$相关index 语句

SQL>  SELECT DBMS_METADATA.GET_DDL('INDEX',INDEX_NAME,'SYS') FROM dba_indexes where owner='SYS' AND TABLE_NAME='OBJ$';
DBMS_METADATA.GET_DDL('INDEX',INDEX_NAME,'SYS')

不同版本对应的基表和index结构不一样(本篇blog使用的是12c做试验),但是本方法支持数据库从Oracle 7到Oracle 12c对于bootstrap$中核心index处理.
因为重建bootstrap$中的核心index是一个复杂而且风险非常大的事情,在你无法确定风险或者无法正常完成此类操作之时,如有需要请联系我

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 owner for a10
SQL> select object_name,owner,object_type
  2  from dba_objects where object_id=4152;
OBJECT_NAME                    OWNER      OBJECT_TYPE

5.分析表和index不一致

----------
         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
