ORA-00283: recovery session canceled due to errors

We have restored a database from backup in different system and while doing the recovery we have received the following the error.

Users will see this error when a new Data file is created and it is not part of the backup. An UNNAMED datafile name is added to the control file and file is created under $ORACLE_HOME/dbs

Errors in file /home/oracle/saptrace/diag/rdbms/orac/ORAC/trace/ORAC_pr00_16269.trc:

Solution:
Find the UNNAMED data file using below command.
SQL> SELECT FILE#, NAME FROM V$DATAFILE
FILE# NAME
-------- -----------------------------------------
1 /dbs01/ORAC/system01.dbf
2 /dbs01/ORAC/sysaux01.dbf
4 /dbs01/ORAC/users01.dbf
5 /home/oracle/11.2.0/dbs/UNNAMED00083
....

Rename an UNNAMED Data file using below command.
SQL> alter database create datafile '/home/oracle/11.2.0/dbs/UNNAMED00083' as '/dbs01/ORAC/ /prd_data83.dbf';
Database altered.

Once you create data file proceed with recovery, if needed.
