今天是2014-06-06，在进行数据库恢复的时候出现了一个久违的ora-600 [2662]错误，特整理如下：
问题描述：
system表空间误删，采用恢复数据文件的方式将数据库恢复到开始状态，数据库为非归档模式。在alter database open resetlog打开数据库的时候提示ora-600 【2662】错误。信息如下：
SQL> col member for a80

问题分析：
出现该问题说明：一个数据块的scn大于当前的scn，对于scn号做一些说明：scn分为高位和地位。高位为wrap占用2bytes，低位为base占用4bytes，对于scn的介绍见如下整理：
http://blog.csdn.net/rhys_oracle/article/details/9052599
那这次报错来看：
ORA-00600: internal error code, arguments: [2662], [0], [1106968], [0], [1107731], [12583040], [], [], [], [], [], []
1106968 为base，1107731为current base，12583040代表：where present this is the DBA where the dependent scn came from。
知道了这些信息之后那么我们就需要采用不同办法去让它增长scn了。
问题解决办法：
重启多次重启数据库，自动增长scn解决问题。

可以看到数据文件的scn已经低于数据的current_scn.
这是一种办法，另还有两种办法：
一种需要数据库open：通过alter session set events ‘immediate trace name adjust_scn level *‘;
一种是数据库必须mount：设置10015事件来完成
alter session set events ‘10015 trace name adjust_scn level *‘;
注意* 代表n，每个n为1那么就是1024*1024*1024
注：对于dblink引起的scn自动大幅度跳跃问题，特别繁琐，之前在运营商处理过这个问题，为避免这些繁琐的问题，最好的办法是关注oracle mos了解安全警戒和打补丁。
That‘s all!
