Make a first estimate for PGA_AGGREGATE_TARGET, based on a rule of thumb. By default, Oracle uses
20% of the SGA size. However, this initial setting may be too low for a large DSS system.
Run a representative workload on the instance and monitor performance, using PGA statistics collected by Oracle, to see whether the maximum PGA size is under-configured or over-configured.
Tune PGA_AGGREGATE_TARGET, using Oracle PGA advice statistics.
