Please crosscheck above point and next time post complete log file what you have done in primary and what you did on standby. Then certainly it can give more clarity and it will be easy to estimate.
Here are the steps ;

Primary -
alter system set log_archive_dest_state_2='enable';
alter system switch logfile;Issues post roll forward -
1)The errors I am getting is same as posted above.
2) Log shipping is moving slowly but my apply is almost stuck
3) Also I see sometimes my archive files of smaller sizes around 30-70M compared to my Normal 900M.
