PGA_AGGREGATE_TARGET formula




Gents,

I was just read Oracle Metalink Note 223730.1 Automatic PGA Memory
Management in 9i. There is a recommended formula for setting PGA on OLTP
and DSS systems. I am interested in OLT system only.
For OLTP the folurma is PGA_AGGREGATE_TARGET = (<Total Physical Memory> *
80%) * 20%

I just want to ask you people, how accurate is this formula?

Best Regards,

Syed Jaffar Hussain
