If you got this error on the Standby side, then convert standby_file_management to manual then stop the dataguard.

SQL> alter system set standby_file_management=manual;

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

Then You need to clear logfile group as follows.

SQL> alter database clear logfile group 1;

SQL> alter database clear logfile group 2;

SQL> alter database clear logfile group 3;

Then you can convert standby_file_management to auto and you can start dataguard as follows.

SQL> alter system set standby_file_management=auto;

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;

Or you can open the database if you don’t get this error on Standby side and if you want to open database, you can open it as follows.

SQL> alter database open;

OR If you need open database with resetlogs option, you can do it as follows.

SQL>ALTER DATABASE OPEN RESETLOGS;
