Computing space occupied by flash recovery area:

SQL> select sum (percent_space_used) * 3/100 from V $ flash_recovery_area_usage;

Sum (percent_space_used) * 3/100

Db_recovery_file_dest string D:/flash_recovery_area
Db_recovery_file_dest_size big integer 2G

2.1033g is already in use. This indicates that db_recovery_file_dest_size = 2 GB is insufficient at the beginning, and the online redo log cannot be archived. Here, we set the db_recovery_file_dest_size parameter, increase the flash recovery area to solve this problem.

SQL> alter system set db_recovery_file_dest_size = 3G scope = both;

The system has been changed.

SQL> alter database open;

The database has been changed.
