Add standby logfiles with below command :-

 alter database add standby logfile group &a ('/u01/app/oracle/oradata/sby1/&a') size 50m;

Make sure you add one extra log group on standby for standby logfiles

#Finally start the MRP Process

SQL> select archived,sequence#,applied,to_Char(completion_Time,'dd-mon-yyyy hh24:mi:ss') from v$archived_log
