Open Hub External System

Question

Hi,
I have a basic requirement to extract data out of Open Hub into an external Oracle database. I have read previous threads online on this topic, but still have a couple of questions that are not clearly answered.
Firstly, my client complies with all licensing arrangements to use Open Hub.They do not want to use flat files and they do not have access to tools like the Microsoft Connector described in many online blogs. 
Secondly, my client would like BW to kick off the process chain, load into an internal BW table, and then raise a trigger to the external Oracle database to come and "pull" the data from the newly created table. I am new to working with API's, but I read about standard API's been available to achieve this, but I would like some simple clarrification:
- In my Process Chain, after I load the Open Hub data into the internal table, I want BW to use the API RSB_API_OHS_3RDPARTY_NOTIFY to tell the external system it's ready to pull the data. Reading the docu about this API, it seems like this needs to be initated from the external Oracle database. Is this correct (I would hope BW could do this) ? And if so, I dont know if my client has these API's on their Oracle system. How do I ensure they do ? I imagine they are freely available, but since I am not a DBA, and do not have access to someone who can tell me or not, I would like to know what the standard procedure for API communication is here. An example or white paper showing the API (with parameters) for a real life scenario would be ideal.
- If the above does not work, even though they say the Microsoft connector tool can be used for Oracle, I am hesitant to use a Microsoft tool, when surely Oracle has their own free tool to do this - or can the Microsoft Connector integrate directly with an Oracle database ??????
- When we refer to the term "Third Party Tool", does this mean a ETL tool like Informatica, or a connection tool like the Microsoft Connector, or the external database like the Oracle database in this example ?
Any clarrification with the above would be most appreciated. I do not have access to a BW system yet, so I would like to know some of the details before I propose a potential solution.
Thanks,
BWPerson
