Solution to Problem:   "ORA-01665: control file is not a standby control file"


The Solution is to put the command to tell dataguard that this is physical standby.

ALTER DATABASE CONVERT TO PHYSICAL STANDBY;
Steps:

SQL> STARTUP MOUNT
SQL> SELECT database_role FROM v$database;
DATABASE_ROLE
—————-
PRIMARY
SQL> ALTER DATABASE CONVERT TO PHYSICAL STANDBY;
SQL> STARTUP MOUNT
SQL> SELECT database_role FROM v$database;
DATABASE_ROLE
—————-
PHYSICAL STANDBY
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;

So, now the control file is for Physical Standby database.
