Your questions on general supportability, robustness, and stability is very dependent on the hardware vendor you decide to go with in implementing OPS, since a very key component of OPS is the o/s distributed lock manager (DLM) which almost always is written not by Oracle but the hardware vendor. I have worked with OPS on Sequents on several client sites and have found them to be very close in stability to running single instance Oracle, while providing very good application throughput scalability. I think the fact that Sequent has been doing OPS and clusters since v6.2 over 4 years ago has given Sequent a strong edge on the learning curve.

I believe Sun's cluster software is fairly new...something to keep in mind.
