bbed打开丢失部分system数据文件库

Posted on by

在某种情况下，数据库system表空间可能有多个数据文件，而意外的丢失了其中某个(不能为第一个),然后通过bbed来模拟一个数据文件来open库
system增加数据文件

SQL> alter tablespace system add datafile '/u01/oracle/oradata/ora11g/system02.dbf' size 10m;

Tablespace altered.

--创建表，为了使得数据库发生类此生产环境的部分操作，使得system表空间可能发生改变
SQL> create table t_xifenfei tablespace system 
  2  as 
  3  select * from dba_tables;

Table created.

删除system中某个文件(system02.dbf)

[oracle@xifenfei ora11g]$ mv system02.dbf system02.dbf_bak

尝试启动数据库

SQL> shutdown abort  
ORACLE instance shut down.
SQL> startup 
ORACLE instance started.

Total System Global Area  313860096 bytes
Fixed Size                  1344652 bytes

Database mounted.
ORA-01157: cannot identify/lock data file 8 - see DBWR trace file
ORA-01110: data file 8: '/u01/oracle/oradata/ora11g/system02.dbf'

错误思路offline system数据文件

SQL> alter database datafile 8 offline;

Database altered.

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01147: SYSTEM tablespace file 8 is offline
ORA-01110: data file 8: '/u01/oracle/oradata/ora11g/system02.dbf'

SQL> alter database datafile 8 online;
alter database datafile 8 online
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 8 - see DBWR trace file
ORA-01110: data file 8: '/u01/oracle/oradata/ora11g/system02.dbf'

使用system表空间其他数据文件来模拟丢失数据文件

[oracle@xifenfei ora11g]$ cp system01.dbf system02.dbf

通过dul获取file$相关信息

FILE#
RELFILE#
CRSCNWRP
CRSCNBAS

bbed修改下面参数值

--rdba
 ub4 rdba_kcbh                         @4        0x02000001
--绝对文件号
 ub2 kccfhfno                          @52       0x0008
--scn
 ub4 kscnbas                           @100      0xc01a3581
 ub2 kscnwrp                           @104      0x0b2c
--相对文件号
 ub4 kcvfhrfn                             @368      0x00000008
--文件大小(不修改,为了重建欺骗数据库重建控制文件)
kccfhfsz
--文件创建时间(重建控制文件来实现控制文件和数据文件头一致)
kcvfhcrt

重建控制文件
1.因为复制来自同一个表空间下面的数据文件，数据文件大小和原数据文件一样, 所以不要修改kccfhfsz大小，不然会出现

CREATE CONTROLFILE REUSE DATABASE "ORA11G" NORESETLOGS       ARCHIVELOG
*
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01200: actual file size of 90880 is smaller than correct size of 10485760 blocks
ORA-01110: data file 8: '/u01/oracle/oradata/ora11g/system02.dbf'

2. 数据文件创建时间是通过kcvfhcrt参数值来控制的，而这个值是通过1988年01月01日00时00分00秒开始计时，按照每月31天计算的累计值，按照这个规则可以推断出来kcvfhcrt.因为数据库在启动的时候会验证控制文件中这个值和数据文件头的该值是否一致，所以如果你不修改kcvfhcrt,可以选择重建控制文件来完成.

再次open数据库

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/u01/oracle/oradata/ora11g/system01.dbf'


SQL> recover database;
Media recovery complete.
SQL> alter database open;

Database altered.

操作到这里,库已经可以正常的被open,如果通过这种方面屏蔽掉的异常的system数据文件中数据字典的部分表信息时,可能数据库依然不能被正常逻辑导出(例如dba_segments,dba_extents的基表等),所以遇到这样的情况,在不确定异常的system中包含的内容之时,还是建议直接使用dul或者第三方工具来抽取数据.

Specify the Begin and End Snapshot Ids
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enter value for begin_snap:

因为没有办法定位到Snap Id,所以暂时无法准确的输入对应值,当然可以通过如下sql查询相应的Snap Id

select SNAP_ID,to_char(SNAP_TIME,'yyyy-mm-dd hh24:mi:ss') SNAP_TIME 
from STATS$SNAPSHOT order by SNAP_ID;

虽然可以通过这个方面来曲线解决这个问题,但是还有比较完善一点的解决方法,我们阅读spcreate.sql相关脚本,修改相关程序来实现

--通过spcreate.sql发现
spcreate.sql调用@@sprepins

--编辑sprepins.sql
column instart_fmt noprint;
column inst_name   format a12  heading 'Instance';
column db_name     format a12  heading 'DB Name';
column snap_id     format 9990 heading 'Snap|Id'; 
-->(修改为)column snap_id     format 999990 heading 'Snap|Id';
column snapdat     format a17  heading 'Snap Started' just c;
column lvl         format 99   heading 'Snap|Level';
column commnt      format a22  heading 'Comment';

再次生成sp报告

ORA-00600[3689]引起MRP进程异常

Posted on by

今天检查数据库发现一数据库因为添加数据文件导致ORA-00600[3689]错误，进入引起MRP进程异常,从而使得数据库可以正常接收归档日志,但是不能在备库应用归档日志
数据库版本

通过观察日志发现，数据库的mrp0进程因为ora-600的错误导致异常终止，从而使得dg备库无法正常使用归档日志

分析trace文件得出

Bug 5230162 : ORA-600[3689][42] ON PHYSICAL STANDBY PREVENT MEDIA RECOVERY描述相符

处理建议
1.10.2.0.1数据库不稳定，bug较多，建议升级数据库到10.2.0.4或者10.2.0.5
2.当前standby_file_management为true，建议修改为false,每次手工两边增加数据文件
3.主库添加数据文件后，观察备库的mrp进程是否正常，如果异常
1)尝试启动mrp进程，如果因为新增加的数据文件导致异常，那先使用rman或者其他方法拷贝主库新建立数据文件到备库，然后启动mrp进程
2)如果因为某种原因导致归档日志出现gap，可以从备份中找出归档日志，如果备份中没有，那可以使用基于scn的备份方式来修复该故障。
3)如果scn相差较大，建议直接重建备库

dual 缺少同义词故障解决

Posted on by

在最近的一个客户案例中,因为缺少dual同义词,导致ddl语句无法执行。这里_system_trig_enabled参数和upgrade模式两种来解决该问题,整体上来说_system_trig_enabled不用重启数据库终止业务,更加人性化.
缺少dual同义词后果

设置_SYSTEM_TRIG_ENABLED重建dual同义词

System altered.

SQL> create public synonym dual for dual;

Synonym created.


SQL> ALTER SYSTEM SET "_SYSTEM_TRIG_ENABLED"=true SCOPE=MEMORY;
