使用conn / as sysdba登录oracle,使用start mount出现此错误

SQL> conn / as sysdba

发现报的错和alert日志显示的一样。
这个错大概是system表空间里面的核心表被删除了,所以数据库启动不起来。这里,如果没有备份的话,这个就不能用常规的手段启动了。

首先去找到报ORA-00704的原因:
SQL> conn / as sysdba
Connected to an idle instance.
SQL> startup mount;
ORACLE instance started.
 
Total System Global Area  4728872960 bytes

SQL> alter session set sql_trace=true;
SQL> select value from v$diag_info where name='Default Trace File';

VALUE

/u01/app/oracle/diag/rdbms/iscba/iscba/trace/iscba_ora_22821.trc

SQL> alter database open;
alter database open
*

Process ID: 2176
Session ID: 128 Serial number: 7

然后查看iscba_ora_22821.trc:

Trace file /u01/app/oracle/diag/rdbms/iscba/iscba/trace/iscba_ora_22821.trc

。。。省略N多字。

发现最后又如下提示:
=====================

这个地方就能确定,是缺失 access$ 造成的数据库启动不起来。
为了解决问题,我们只有用非常规的手段来自己创建这个表,来进行恢复,步骤如下:
1.启动数据库到upgrade状态
SQL> startup  upgrade
ORACLE instance started.
 
Total System Global Area  4728872960 bytes
Fixed Size            1314156  bytes
Variable Size          163578516  bytes
Database Buffers      1019898880 bytes
Redo Buffers            6004736  bytes
Database mounted.
Database opened.

2.创建access$ 和相关的索引
SQL> create table access$
  2  ( d_obj#        number not null,
  3    order#        number not null,
  4    columns       raw(126),
  5    types         number not null)
  6    storage (initial 10k next 100k maxextents unlimited pctincrease 0)
  7  /
 
Table created.
 
SQL> create index i_access1 on
  2    access$(d_obj#, order#)
  3    storage (initial 10k next 100k maxextents unlimited pctincrease 0)
  4  /
 
Index created.
注意:创建语句可以在$ORACLE_HOME/RDBMS/ADMIN/dcore.bsq中找到

3.重启数据库
QL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
 
Total System Global Area  4728872960 bytes
Fixed Size            1314156  bytes
Variable Size          163578516  bytes
Database Buffers      1019898880 bytes
Redo Buffers            6004736  bytes
Database mounted.
Database opened.

4.检查状态并用tnsname去连接
select status from v$instance;
sqlplus username/password@TNSNAMES
