How to resolve the errors so that the recovery process could proceed so that the physical standby could be in sync with the primary database?
Solution:
perform the following steps on the physical standby database to resolve the issue
On standby database run following command to find missing files
SQL> select FILE#||','||ERROR||','||STATUS||','||RECOVER||','||FUZZY||','||NAME 
from v$datafile_header where ERROR='FILE MISSING';
cancel the managed recovery
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Set standby_file_management=manual
SQL>ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=MANUAL;
If the physical standby database is RAC, then please make the change to all standby instances
SQL>ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=MANUAL SID='*';
Rename the unknown datafile 8
alter database create datafile '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/UNNAMED00008' as 
'absolute path/real datafile name' ;
For ASM
alter database create datafile '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/UNNAMED00008' as 
'+DG01' size 'actual size of datafile on Primary';
Set standby_file_management=auto
SQL>ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO SID='*';
Start managed recovery
SQL>ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
