Summary: (eygle :)

1: as long as you have the current log file, you can perform full recovery. Do you need to open it in resetlogs mode,

Depends on whether the backup control file is used.

2: If there is no loss to the log file, you can re-create the control file to restore it completely.

In this case, you no longer need to use the resetlogs method to open the database.
