Joakim
Correct me if I'm wrong, but the two statements you've used are:
> E.g, processes = 9550, shared_pool_size = 300,000,000 OK
> proccess = 9555, shared_pool_size = 800,000,000 FAILED.
i.e. you've just increased the shared pool by 500,000,000. You're still looking at an out of memory error. The increase in processes will have minimal impact, but you're nearly tripling the size of the SGA by the shared_pool_size increase. Have you looked at how much memory is available (NOT how much there is total)?
