Create Standby database using SE
There is some misunderstanding here.

Your alert log shows that you were trying to use Data Guard features, this is clearly not a manual standby.

A manual standby is a copy of the "primary" database continuously rolled forward manually with the archive logs from the "primary" database. 
You transfer the archivelogs with OS commands, e.g. scp or rsync. Then you periodically register the archivelogs and recover the database with RMAN or SQL*Plus user managed recovery, but definitely not the Data Guard Media Recovery Process.
Data Guard is not involved at all, so there is no need for a standby controlfile, just a regular controlfile.
