Media Recovery Complete(CRM)
注意：通过跟踪整个恢复过程，可以清楚的观察到在用recover进行完全恢复时，先应用归档，后再通过所有联机日志文件推进整个数据库来实现完全恢复的过程。
8 如果数据库进行不完全恢复如何获取恢复所需要的归档
以基于时间点恢复为例，我们可以这么使用得出恢复到这个时间点数据库需要的归档列表。
run{
sql 'alter session setnls_date_format="yyyy-mm-dd hh24:mi:ss"';
set until time='2013-12-09:05:50:12';
restore database preview;
}
总结：
1 在对数据库进行恢复的时，第一步先看看数据库是否归档，第二步看看数据库是否有备份，第三步验证备份和归档的有效性。最后执行整个恢复过程。
2 完全恢复时，通过对比restore database preview 显示的归档列表seq号和联机日志组的seq号，我们便可以清楚的推出数据库完全恢复时，recover需要应用的归档。
