SQL> show parameter sga_max_size
NAME TYPE VALUE
—————————— ————— —————–
sga_max_size big integer 500M
SQL> show parameter target
NAME TYPE VALUE
—————————— ————— ——————
archive_lag_target integer 0
db_flashback_retention_target integer 1440
fast_start_io_target integer 0
fast_start_mttr_target integer 0
memory_max_target big integer 0
memory_target big integer 0
pga_aggregate_target big integer 384M
sga_target big integer 384M
Which is the best solution that you would recommend?
A.
Increase the value of the SGA_MAX_SIZE parameter.
B.
Set MEMORY_MAX_TARGET and MEMORY_TARGET parameters.
C.
Reduce the value of the PGA_AGGREGATE_TARGET parameter.
D.
Increase the value of both SGA_TARGET and PGA_AGGREGATE_TARGET parameters.
E.
Diagnose further to identify which component in SGA is undersized and then resize it.
