ORA-600[2662] – Database SOS

使用bbed解决ORA-00600[2662]

一、数据库启动报ORA-00600[2662]

三.分析日志
ORA-00600[2662]主要参数说明见:ORA-00600 [2662]
这里补充说明:e表示出现异常问题的数据块的DBA,这里的4194432就是一个数据块的DBA

--通过DBA地址查询数据块和文件号

四.bbed查看相关SCN

这里看到的SCN(16进制)和我们在alert日志中看到的有一定的出入原因是在数据库启动的时候，当前SCN增加了，但是因为数据库直接abort，没有写入到数据文件中。导致数据文件头部的SCN比alert中显示的稍微小一点(还有可能，系统当前的scn比system01.dbf的scn大一点)。通过对比数据块和数据文件头部的SCN也可以说明当数据块的SCN>数据块当前SCN导致ORA-00600[2662]

七.补充说明
一般遇到ORA-00600[2662]都是使用alter session set events ‘10015 trace name adjust_scn level N’;方法处理，但是有时候会遇到ORA-01031错误，那就需要请bbed帮忙处理

二、查询是损坏日志组

SQL> col member for a35
SQL> select a.group#,a.status,b.member from v$log a,v$logfile b
   2 where a.group#=b.group#;
    GROUP# STATUS           MEMBER
---------- ---------------- -----------------------------------
         3 CURRENT          R:\ORADATA\HZYL\REDO03.LOG
         2 INACTIVE         R:\ORADATA\HZYL\REDO02.LOG
         1 INACTIVE         R:\ORADATA\HZYL\REDO01.LOG

确定是因为断电导致当前redo 损坏，需要使用隐含参数+不完全恢复处理(经验)

三、不完全恢复

SQL> recover database until cancel;
ORA-00279: 更改 9743796718 (在 12/05/2011 09:07:40 生成) 对于线程 1 是必需的

ORA-01194: 文件 1 需要更多的恢复来保持一致性
ORA-01110: 数据文件 1: 'R:\ORADATA\HZYL\SYSTEM01.DBF'

四、启用隐含参数，尝试打开数据库

SQL> create pfile='d:/1.txt' from spfile;
文件已创建。
#############添加隐含参数##################
*._allow_resetlogs_corruption=TRUE
*._allow_error_simulation=TRUE

五、查看alert日志

这里看到熟悉的ora-600 [2662]，处理方法增加scn，参考ORA-00600 [2662]

六、增加SCN，打开数据库

打开过程中，出现ORA-00600[2256]，但是数据库还是正常打开，具体原因待研究

ORA-00600 [2662]

联系：手机/微信(+86 17813235971) QQ(107644445)

标题：ORA-00600 [2662]

一、错误现象（alert日志中）
Errors in file /opt/oracle/admin/conner/udump/conner_ora_31607.trc:
ORA-00600: internal error code, arguments: [2662], [0], [897694446], [0], [897695488], [8388697], [], []

二、错误解释
ORA-600 [2662] “Block SCN is ahead of Current SCN”，说明当前数据库的数据块的SCN早于当前的SCN，主要是和存储在UGA变量中的dependent SCN进行比较，如果当前的SCN小于它，数据库就会产生这个ORA-600 [2662]的错误了。这个错误一共有五个参数，分别代表不同的含义
ORA-600 [2662] [a] [b] {c} [d] [e]
Arg [a] Current SCN WRAP
Arg [b] Current SCN BASE
Arg {c} dependent SCN WRAP
Arg [d] dependent SCN BASE
Arg [e] Where present this is the DBA where the dependent SCN came from.
注：897694446<897695488
三、错误原因
1.使用隐含参数_ALLOW_RESETLOGS_CORRUPTION后resetlogs打开数据库
2.硬件错误引起数据库没法写控制文件和重做日志文件
3.错误的部分恢复数据库
4.恢复了控制文件但是没有使用recover database using backup controlfile进行恢复
5.数据库crash后设置了_DISABLE_LOGGING隐含参数
6.在并行服务器环境中DLM存在问题

四、解决办法
1、如果SCN相差不多，可以通过多次重起数据库解决（每次加1）
2、通过10015 ADJUST_SCN事件来增进current SCN
1）计算level
1.1) Arg {c}* 4得出一个数值，假设为V_Wrap
1.2) 如果Arg [d]=0，则V_Wrap值为需要的level
Arg [d] < 1073741824，V_Wrap+1为需要的level Arg [d] < 2147483648，V_Wrap+2为需要的level Arg [d] < 3221225472，V_Wrap+3为需要的level 1.3）SCN被增进了1024*1024*1024*level（level*10 billion）
2）执行内部事件
alter session set events ‘10015 trace name adjust_scn level N’;
注：mount状态下执行（open下无效）
alert日志中会出现：
Sat Aug 20 15:41:07 2011
Debugging event used to advance scn to 107374182400
