由于我遇到的一些问题，我在oracle 11g上尝试以下查询。但它的投掷错误。有人可以帮忙吗

查询：alter database open

*   第1行的错误：   ORA-00600：内部错误代码，参数：[kcratr_nab_less_than_odr]，[1]，   [505]，[33717]，[33719]，[]，[]，[]，[]，[]，[]，[]

Answer 1

使用ORA-00600更改数据库打开失败kcratr_nab_less_than_odr

Option a:  Do cancel based reocvery, and apply 'current online redolog' manually
------------

SQL>Startup mount ;

SQL>Show parameter control_files

Query 1
------------

SQL> select a.member, a.group#, b.status from v$logfile a ,v$log b where a.group#=b.group# and b.status='CURRENT' ;

Note down the name of the redo log

SQL> Shutdown abort ;

Take a OS Level backup of the controlfile (This is to ensure we have a backup of current state of controlfile)

SQL> Startup mount ;
SQL> recover database using backup controlfile until cancel ;

Enter location of redo log shown as current in Query 1 when prompted for recovery

Hit Enter

SQL> Alter database open resetlogs ;


Option b: Recreate the controlfile using the Controlfile recreation script
-----------

NOTE:  If you are using RMAN backup without a catalog, you will need to catalog the backups after the controlfile is recreated.  For tape backups, capture your backup information before recreating the controlfile as this will be needed.  

With database in mount stage

$ rman target /
rman> spool log to '/tmp/rman.log';
rman> list backup ;
rman> exit

# Keep this log handy

Go to sqlplus

SQL> Show parameter control_files 

Keep this location handy.

SQL> oradebug setmypid 
SQL> Alter session set tracefile_identifier='controlfilerecreate' ;
SQL> Alter database backup controlfile to trace noresetlogs;
SQL> oradebug tracefile_name ; --> This command will give the path and name of the trace file

Go to this location ,Open this trace file and select the controlfile recreation script with NOResetlogs option 

SQL> Shutdown immediate;

Rename the existing controlfile to <originalname>_old ---> This is Important as we need to have a backup of existing controlfile since we plan to recreate it

SQL> Startup nomount

Now run the Controlfile recreation script with NO Resetlogs option.

SQL> Alter database open ;

For database version 10g and above 

Once database is opened you can recatalog the rman backup information present in the list /tmp/rman.log using

Rman> Catalog start with '<location of backupiece>' ;

If backups are on tape, and you are not using a catalog, backups can be cataloged using information in:
How to Catalog Tape Backup Pieces (Doc ID 550082.1)

Once the database has been opened using the Option a or Option b,  it is recommended to take a hot backup of the database.  The same steps are applicable to RAC if all instance are down with same error.

If  both Options (a|b) fails,  or you do not have the full set of files, then you have to restore and recover the Database from a recent Backup.

Answer 2

ORA-00600消息是Oracle内核代码中未处理副作用的全部消息，即错误。这些东西往往特定于Oracle数据库的版本，通常也是OS和服务器。

此类事情的标准方法是使用Oracle Support提出服务请求。这看起来是11gR2基础版本中的已知错误。（支持说明ID 1296264.1）

但是，如果您在2015年仍在运行未修补的11.2.0.1实例，我猜您很可能没有支持合同。在这种情况下，您没有太多选择。

这blog article suggests a couple of things you can try。（关于你在网上看到的东西的常见警告）。两者都需要DBA和/或sysadmin能力。
