On standby :
$ mkdir -p /data01/app/oracle/oradata/orcl/     --> Datafiles
$ mkdir -p /data01/app/oracle/arch              --> Archive
$ mkdir -p /data01/app/oracle/admin/orcl/adump  -->  audit_file_dest

Copy the files from the primary to the standby server:
 # Standby controlfile to all locations.
  scp /tmp/orcl_stndby.ctl oracle@node2:/data01/app/oracle/oradata/orcl/control01.ctl
  scp /tmp/orcl_stndby.ctl oracle@node2:/data01/app/oracle/oradata/orcl/control02.ctl

$ # Parameter file.
$ scp /tmp/pfile.ora oracle@node2:/tmp/pfile_orcl_node2.ora
$ # Remote login password file.
scp /data01/app/oracle/product/11.2.0.3/db_1/dbs/orapwORCL  oracle@node2:/data01/app/oracle/product/11.2.0.3/db_1/dbs/orapwORCL
Start Listener on standby :
Create a static listener and start is on standby :

Create Standby Redo Logs on Primary Server :
