There is a very detailed white paper that describes the set up of a shared remote database for access by multiple BCM instances. There have been several inquiries about this type of deployment and I wanted to highlight that it is possible, easy to do and there is a detailed guide that we have written to assist with this. I hope this white paper is useful. As always if there is anything we can do do make it better, feel free to send email or comment about the guide.
We are also working on a tool that will make BCM setup with SBS server sharing easier in the future.
