clean up of multi-master environment?

Hi,.I've been experimenting with multi-master replication between two sites ove the past week or so and now I want to remove all traces of my work so I can perform and clean, proper build. I've scoured the documentation and the knowledge base etc but I cant find any instructions that successfully clear out all of my replication config from the relevant data dictionary objects. I did find artile 885586.1 but a number of the truncate commands failed which could be becauses its for up to 11.1 and I'm running 11.2.0.3. Does anyone know how to completely clear all replication config
