Pritam,

The SCA (scalability) feature in OTM is very advanced. It's been in the product since around v4.0, but for various reasons, has not really been production tested until recently. Currently, I'm only aware of a couple production clients using it, primarily in domain-split SCA mode. Currently no one is utilizing the functional-split SCA to my knowledge, but I do know of a few companies that are considering it. The biggest problem you'll it (as you identified) is splitting out logical functions into the those defined within the Admin UI, so that you can assign them. Currently, there's no definitive resource for this -- it all comes down to experience and understanding how the underlying functional architecture fits together. As for the full active/active clustering -- it currently doesn't perform well, but it expected to improve in v6.0.

If you're experimenting with SCA, then make sure you're at least at the OTM V5.5 CU4 patch level -- as there were significant improvements within this patch. This is also the base patch that Oracle will require in order to support your efforts.

As for the documentation -- you're right, it's currently poor and hasn't really been updated since v4.0. There is a workshop in April that Oracle is holding, in order to discuss all of the features of SCA, gather real-world experience and improve their documentation. I don't know how long it will take to get deliverables out of this workshop, but do know that we will be involved in the process.

I can share more details as they become available. In the meantime, if you have specific questions, post them and we can help. I've setup SCA a lot of times, both in QA environments at G-Log and for customers experimenting with it since.
