Re: Tuning SGA

Robert,

Often times hardware is leased for a 3 year contract. I've often seen a server that was performing acceptably (that had a robust storage subsystem) be taken offline and replaced with screaming fast new CPUs, high memory bandwidth box that has a ridiculously poor storage subsystem that has 73 GB (or larger) hard drives.

As long as the buffer cache hit ratio is > 0.9999 no one is likely to complain, except for the dba.

De-coupling server and storage is the way to go.
