  1. 我做了个实验：ctl 的 CHECKPOINT_CHANGE#  小于 数据文件头的 CHECKPOINT_CHANGE# ,数据库需要恢复

  3. SQL>  select  CHECKPOINT_CHANGE#   from v$$$$database;

  5. CHECKPOINT_CHANGE#
  6. ------------------
  7.             954672

  9. SQL> select CHECKPOINT_CHANGE#,last_change# from v$$$$datafile;

  11. CHECKPOINT_CHANGE# LAST_CHANGE#
  12. ------------------ ------------
  13.             954672
  14.             954672
  15.             954672
  16.             954672
  17.             954672


  20. SQL> select CHECKPOINT_CHANGE# from v$$$$datafile_header;

  22. CHECKPOINT_CHANGE#
  23. ------------------
  24.             957729
  25.             957729
  26.             957729
  27.             957729
  28.             957729

为什么不需要 恢复？

controlfile checkpoint_change# <  datafile header checkpoint_change# 为什么不需要恢复？

照你这么说   我先shutdown abort一把， 然后restore一个老的控制文件，而老的控制文件的checkpoint_change< datafile里的， 那么这个场景满足你的条件也不用恢复咯？

总结：
controlfile checkpoint_change# <  datafile header checkpoint_change# 的时候，定要恢复

SQL>recover database using backup controlfile;
恢复原理： 先应用归档日志，再需要手动指定 CURRENT 日志

SQL> alter database open resetlogs;
