Unable to open database - flashback

satish
Dear Erman,

we need your help.

Oracle database 2 node rac 19c
application R12.2.5

Unfortunately,my team mate deleted the flashback logs. We are unable to start the instance. We tried to drop the restore point but it errors out. This is UAT. Is there is anyway to bring up the database.

SQL> alter database flashback on;
alter database flashback on
*
ERROR at line 1:
ORA-38706: Cannot turn on FLASHBACK DATABASE logging.
ORA-38714: Instance recovery required.

SQL> drop restore point CLEAN_DB;
drop restore point CLEAN_DB

We have free space available. Not sure what else we can check.

Thanks,
