此时我们可以通过Oracle的内部事件来调整SCN:

增进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。

设置event adjust_scn：

alter session set events '10015 trace name adjust_scn level 1';
