RMAN 执行表空间恢复的步骤：
1. Creates the auxiliary instance, starts it, and connects to it
2. Takes the tablespaces that will be recovered offline
3. Restores a backup control file from a point in time before the target time to the auxiliary instance
4. Restores the data files from the recovery set and the auxiliary set to the auxiliary instance
5. Recovers the restored data files to the specified time
6. Opens the auxiliary database with the RESETLOGS option
7. Exports the dictionary metadata about objects in the recovered tablespaces to the target database
8. Shuts down the auxiliary instance. (Issues SWITCH commands on the target database so that the target database control file points to the data files in the recovery set that were recovered on the auxiliary instance)
9. Imports the dictionary metadata from the auxiliary instance to the target instance
10. Deletes all auxiliary set files
