Typical

Typical—This method requires little configuration, and allocates memory as a
percentage of total overall physical system memory. Select Typical and enter a
value in the Memory Size (SGA and PGA) field. The percentage of memory
represented by the value entered is shown in the Percentage field. You can also
use the slider to change the value. Click Show Memory Distribution to view the
SGA size and PGA size allocated. Click Use Automatic Memory Management to
have the system automatically tunes many of the memory components of the SGA,
and allocate memory to individual PGAs as needed. The system can also
dynamically decrease or increase the total amount of memory allocated to the SGA
or aggregate PGA, depending on processing demands. The total memory used for
the database instance never exceeds the amount you specify. This automatic
memory tuning for the instance is known as automatic memory management. To
learn more about PGA and SGA, see "About Instance Memory Structures" on
page 5-4.
