Need Clarification on sga_target and sga_max_size

user8665771Sep 7 2012 — edited Sep 7 2012
HI,

I need some clarification in SGA_TARGET and SGA_MAX_SIZE.
I have the parameter like below.
SGA_MAX_SIZE=10G
SGA_TARGET=9G

And I spread the 9G to all components like (DB_CACHE,SHARE_POOL etc.,).

My doubt, Incase db need the memory more than 9GB, Whether it automatically take the extra 1G from sga_max_size
or we have to change the sga_target to 10G.
