如果resetlogs方式打开有问题，在alert文件中有ORA-00600 [2662]信息，

就这样：

SQL> shutdown;
SQL>startup mount pfile='/tmp/init.ora';
SQL>ALTER SESSION SET EVENTS '10015 TRACE NAME ADJUST_SCN LEVEL 1';
SQL>alter database open;

1：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.

2：于是想到使用ADJUST_SCN事件来调整当前的SCN，使其大于dependent SCN.

3：此时我们可以通过Oracle的内部事件来调整SCN:

调整SCN有两种常用方法:

1.通过immediate trace name方式(在数据库Open状态下)

alter session set events 'IMMEDIATE trace name ADJUST_SCN level x';

2.通过10015事件(在数据库无法打开，mount状态下)

alter session set events '10015 trace name adjust_scn level x';

注:level 1为增进SCN 10亿 (1 billion) (1024*1024*1024),通常Level 1已经足够。也可以根据实际情况适当调整。

楼主的例子由于数据库无法打开，只能使用第二种方法。
