Thanks for the response, Sybrand.
Two reasons: First, the application vendor does not support RAC, except maybe as active/passive. But for that the RAC licence cost is prohibitively expensive.
Secondly, whether we like it or not, the customer is a dedicated IBM shop (personally I have doubts about AIX being the best *nix platform for Oracle; I would far rather use Solaris or HP/UX). So HACMP is a given.
In any case, the architectural decisions have been made; I am just the poor DBA who has actually to do the implementation. Can you offer some practical advice?
Thanks,
