Syncing to AD codeless without portal interaction

Hi,

I'm looking at implementing FIM 2010 R2 to sync user information from an Oracle DB to AD. I don't want to use classic rules I don't have the experience or knowledge of C to code my own DLLs. My understanding is that to do this using declarative rules, I'd need at least 3 MA and configure them as follows:

Oracle MA - import, sync & export
FIM MA - import, sync & export
AD MA - import, sync & export

In the above scenario all my Oracle user information would be imported into the FIM portal and exported to AD.

Is it possible to simplify the above when using declarative sync rules so that I go directly from the Oracle data source to AD, without using the portal?

Thanks
