Posted on by

今天早上一个朋友和我说他们RAC dbca创建库不成功提示ORA-00443错误,让我帮他们分析下是什么原因导致
提示错误如图

--------------------- Binary Stack Dump ---------------------

通过查询MOS发现[ID 422908.1]有类此的错误提示,但是该提示说是因为系统重新增加了过多CPU导致数据库crashed掉并且出现 ORA-27300 ORA-27301 ORA-27302 错误.在该案例中,起始就是64c,根据经验在win的10.2.0.4中如果cpu超过32c也是在dbcd创建数据库2%的地方hang住,所以怀疑该错误也是由于cpu太多导致.

处理方法

To solve the problem:

1) apply patch:6471079

- or -

2) apply the 10.2.0.5 (when available)

- or -

3) upgrade to 11g

朋友打上patch:6471079,dbca正常建库

_no_recovery_through_resetlogs参数功能探讨

_no_recovery_through_resetlogs参数默认值和描述

SQL> select a.ksppinm name,b.ksppstvl value,a.ksppdesc description
  2    from x$ksppi a,x$ksppcv b
  3   where a.inst_id = USERENV ('Instance')
  4     and b.inst_id = USERENV ('Instance')
  5     and a.indx = b.indx

  7  order by name
  8  /
Enter value for param: _no_recovery_through_resetlogs
old   6:    and upper(a.ksppinm) LIKE upper('%&param%')
new   6:    and upper(a.ksppinm) LIKE upper('%_no_recovery_through_resetlogs%')

NAME                             VALUE                    DESCRIPTION
-------------------------------- ------------------------ --------------------------------------------
_no_recovery_through_resetlogs   FALSE                    no recovery through this resetlogs operation

大家知道在10gr2版本及其以后版本,大家知道默认情况下,可以实现跨resetlogs恢复数据库.通过该参数的描述可以看出,该参数的用途是使得resetlogs之后不能继续进行恢复(我的理解是以前的备份不能应用resetlogs后的归档日志)
在实际中该函数的作用是否和该参数的描述相符,我们通过试验验证

通过这里的测试证明使用_no_recovery_through_resetlogs=true后,resetlogs之后还是可以正常可以recover相关日志,证明_no_recovery_through_resetlogs参数不是限制这里的resetlogs后的归档日志应用,至于该参数的具体用途也希望知道的朋友告知下。但是这个参数在clone db和从rac db恢复到单实例db的时候,可能因为bug原因需要设置该参数为true,如:

--rac恢复到单实例RMAN Duplicate from RAC backup fails ORA-38856 [ID 334899.1]

ORA-38856: cannot mark instance UNNAMED_INSTANCE_2 (redo thread 2) as enabled

控制文件异常导致ORA-00600[kccsbck_first]

Posted on by

今天接到一个朋友求救他们的his系统数据库不能访问,情况比较紧急,让我帮忙处理.登录数据库得到信息如下:

操作系统:windows 2003
数据库:8.1.7
容灾方案：双机+emc存储镜像
备份:数据库无任何备份
启动到mount报错类此:
ORA-00600: internal error code, arguments: [kccsbck_first], [1], [4141358753], [], [], [], [], []

这个问题在上周的数据库恢复中遇到过一次,他们也是因为双机的案例,当时的情况见:双机mount数据库出现ORA-00600[kccsbck_first],有了上次的思维,我开始也怀疑是客户的双机的问题,但是客户说双机在半年前就关闭了,没有启动过;因为我对win的双机不太熟悉,怕他们双机软自动启动系统然后接管oracle从而导致这个问题,然后让客户检查另一台机器，确定没有启动和接管oracle 服务.
然后查询MOS发现win上面的特殊之处:是控制文件corruption导致故障(不过dbv检查不出来),而且三个控制文件有同样的问题
MOS记录如下(不过8.1.7也存在同样问题) [ID 291684.1]

Symptoms



Alter database mount exclusive results in

ORA-00600: internal error code, arguments: [kccsbck_first], [1], [2141358753], [], [], [], [], []

The description of the error is:

'We receive this error because we are attempting to be the first 
thread/instance to mount the database and cannot because it appears that 
at least one other thread has mounted the database already'.


However in this case the database was a standalone database on Windows.
It had only one oracle service running.

The operating system was rebooted, the oracle service was deleted and a new service created.
Even then the error persisted. 
Cause

There was some corruption present in the controlfile.


Solution

In this case the problem was resolved by:

+ Taking a backup of the old control file

+ Recreating the control file using the following document
How to Recreate a Controlfile	 [Document 735106.1]

因为数据库不能mount,所以不能使用backup controlfile to trace;
因为是win系统,没有任何的控制文件备份,只能把控制文件拷贝到linux下面通过strings命令,自己编辑创建控制文件脚本(noresetlogs).执行脚本创建控制文件,recover database,应用redo文件恢复,然后resetlogs库,恢复成功(注意:8i中不需要另外增加临时文件)
