标签归档：ORA-08103

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

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)
  TABLESPACE "SYSTEM"

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
