The DBA has chosen to manage SGA and PGA memory separately in an OLTP database because of
his unique knowledge of the application. Which of these are good starting points to use when configuring
the maximum values for SGA and PGA, based on the amount of memory available on the system?
A. 20% SGA, 80% PGA
B. 25% SGA, 75% PGA
C. 50% SGA, 50% PGA
D. 75% SGA, 25% PGA
E. 80% SGA, 20% PGA
A good starting point is to use approximately 20 percent of the available memory for the PGA and
approximately 80 percent for SGA.
