The alternative would be to have 25 instances running on each server
each with buffer cache, large pool, shared pool, java pool, redo
buffers plus each of these instances would have up to 20 oracle
processes and there would also be 25 different database caches talking
to each other from one blade server to another. Finally there's
additional licensing cost plus some possible changes when moving a
non-RAC database to RAC, 5 sets of archive/redo logs, 5 alert log files
/ database. I think that makes for a lot of overhead which is why I'm
thinking the non RAC idea of the virtual servers would be the way to
go. I should also mention that high availability is important but not
critical for these databases.
