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.
尝试rebuild index

因为是数据库核心index,无法直接rebuild解决,只能通过bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决 方式解决
bootstrap$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
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 -------------------------------------------------------------------------------- CREATE UNIQUE INDEX I_OBJ1 ON OBJ$(OBJ#,OWNER#,TYPE#) PCTFREE 10 INITRANS 2 MAXT RANS 255 STORAGE ( INITIAL 64K NEXT 1024K MINEXTENTS 1 MAXEXTENTS 2147483645 PC TINCREASE 0 OBJNO 36 EXTENTS (FILE 1 BLOCK 336))
2. 创建获取异常index所属表
SQL> select table_name from dba_indexes where owner='SYS' AND INDEX_NAME='I_OBJ1'; TABLE_NAME -------------------------------------------------------------------------------- OBJ$
3. 获取obj$ ddl 语句

4. 获取obj$相关index 语句

5. 创建obj$img表和相关index

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

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
