You set the following parameters in the parameter file and restarted the database:
MEMORY_MAX_TARGET=0 MEMORY_TARGET=500M
PGA_AGGREGATE_TARGET=90M SGA_TARGET=270M Which two statements are true
about these parameters after the database instance is restarted? (Choose two.)
A.
The lower bounds of PGA_AGGREGATE_TARGET and SGA_TARGET parameters are
set to 90 MB and 270 MB, respectively.
B.
The value of the MEMORY_MAX_TARGET parameter remains zero until it is changed
manually.
C.
The PGA_AGGREGATE_TARGET and SGA_TARGET parameters are automatically set
to zero.
