Property Description
Parameter type Big integer
Syntax MEMORY_TARGET = integer [K | M | G]
Default value 0
Range of values 152 MB to MEMORY_MAX_TARGET
Basic No

MEMORY_TARGET specifies the Oracle system-wide usable memory. The database tunes memory to the MEMORY_TARGET value, reducing or enlarging the SGA and PGA as needed.

In a text-based initialization parameter file, if you omit MEMORY_MAX_TARGET and include a value for MEMORY_TARGET, then the database automatically sets MEMORY_MAX_TARGET to the value of MEMORY_TARGET. If you omit the line for MEMORY_TARGET and include a value for MEMORY_MAX_TARGET, the MEMORY_TARGET parameter defaults to zero. After startup, you can then dynamically change MEMORY_TARGET to a nonzero value, provided that it does not exceed the value of MEMORY_MAX_TARGET.


The default value of SGA_MAX_SIZE depends on the values of MEMORY_TARGET and MEMORY_MAX_TARGET.
