Try:
create database link sales connect to hrm identified by hrm using 'sales';

You can also create it using this form (which allows you to create multiple DB links to the same database from that account, and helps to remind you where it points to.

create database link sales@hrm connect to hrm identified by hrm using 'sales';
create database link sales@scott connect to scott identified by tiger using 'sales';

'sales' must be defined in the server's tnsnames.ora file.

The host string is in single quotes:

create database link sales@scott connect to scott identified by tiger using 'sales';
