通过对控制文件进行处理,再次尝试recover库

由于redo和数据文件不匹配,无法正常recover库,尝试强制打开库报ORA-600 2662错误

发现报ORA-32521错误,证明常规的oradebug方法无法修改scn,参考相关文章:

根据以往经验记录一次ORA-00600[2252]故障解决,很可能是scn过大引起.通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检查scn相关信息
scn

从ORA-600 2252错误信息看,由于scn可能超过该数据库的天花板理论上而导致该问题,而reco进程主要是由于分布式事务引起,通过和客户确认,该库有通过dblink去访问11204版本oracle,而从2019年6月23日之后scn的算法发生了一些改变(SCN Compatibility问题汇总-2019年6月23日),导致数据库可以支持更大的scn,从而当低版本需要进行分布式事务操作之时,可能导致数据库异常.

处理方案：通过临时屏蔽分布式事务,让数据库临时正常工作;长期解决方案需要把数据库版本升级,避免scn引起相关问题

ORA-600 17182导致oracle异常

通过这些日志可以看出数据库一直在报ORA-00600[2252],在后来因某种原因数据库异常重启后启动不了.仔细观察可以发现系统显示的时间是2010年6月7日和当前时间相差了整整两年.
At any point in time, the Oracle Database calculates a “not to exceed” limit for the number of SCNs a database can have used, based on the number of seconds elapsed since 1988, multiplied by 16,384. This is known as the database’s current maximum SCN limit. Doing this ensures that Oracle Databases will ration SCNs over time, allowing over 500 years of data processing for any Oracle Database.

错误原因
根据错误提示计算scn(2834为现在系统的SCN WRAP，4076604085就是BASE)=2834*2^32+4076604085=12176013920949
根据数据库日志显示系统时间计算最大scn值:

SQL>select to_number( ((to_date('20100607 09:19:28','yyyymmdd hh24:mi:ss')-
  2 to_date('19880101','yyyymmdd'))*24*3600*16*1024),'999999999999999999') max_scn from dual;
   MAX_SCN
--------------
11598377254912

通过这里的计算可以知道数据库当前的SCN大于系统时间点上允许的最大时间的SCN,从而出现ORA-00600[2252]错误.

解决方法
知道了数据库报该错误的原因,那么解决该问题很简单,修改系统时间到正确的时间点即可

SQL> select to_number(((sysdate-to_date('19880101','yyyymmdd'))*24*3600*16*1024),
   2 '999999999999999999') max_scn from dual;
   MAX_SCN
--------------
12634899464192

该SCN大于数据库当前SCN所有数据库不会报ORA-00600[2252]错误可以正常启动.
