I just read the documentation and Oracle strongly discourages renicing Oracle processes. My first idea was in fact starting the instances under different accounts and using ulimit and the like to set a top limit for CPU use. But no, it should not be done. Even using the Solaris Resource Manager must be done carefully to avoid interactions with Oracle internal resource management.

What I did today was to set up Consumer Groups and Resource Plans, only to ease concurrency *inside* every instance. My main problem still persists.
