[Oracle Active DataGuard 12.1 Installation on Centos 6.7]: Creating directories on standby that exist on primary

The point of this step is that if, for example, a directory where files need to be copied is specified but does not exist on the server, the copy procedure will fail.

In my case, it only failed due to the missing directory /u01/oracle/admin/orcl12/adump

On Primary
