I'm not sure which of the linked articles you're following, but I expect that you're making things more complicated than they need to be. Those articles discuss configuring multi-master replication, but it sounds like you only need simple materialized view replication. In that case, all you'd need to do is
1) Create a database link from the destination system to the source system
2) Create a materialized view log on the source table on the source system
3) Create a materialized view on the destination that selects all the data from the remote table and is set to be fast refreshable and to refresh every 5 minutes.
On the destination system
CREATE DATABASE LINK to_source_system
  CONNECT TO username_on_source_system
  IDENTIFIED BY password_on_source_system
  USING 'tns_name_for_source_system_on_dest_system';On the source system
CREATE MATERIALIZED VIEW LOG
  ON table_to_replicate
  WITH PRIMARY KEY
  INCLUDING NEW VALUES;On the destination system
CREATE MATERIALIZED VIEW table_to_replicate
  REFRESH FAST
  START WITH sysdate + 5/(24*60)
  NEXT sysdate + 5/(24*60)
AS
SELECT * FROM table_to_replicate@to_source_systemIf you have multiple tables that you want to be replicated in a transactionally consistent manner, you can put multiple materialized views into a refresh group and schedule a refresh of the refresh group.
