Oh, that makes more sense. First I would look and see what the AWR report
says in the memory advisors section. A general rule of thumb for a
dedicated Oracle server is Oracle can have about 75% of the memory on the
box in whatever combination is best. If it is a data warehouse, you
generally want a larger PGA. If it is an OLTP system, you generally want a
larger sga_target/sga_max_size.
