I have a linux box,

Linux 2.6.9-5.ELsmp #1 SMP Wed Jan 5 19:30:39 EST 2005 i686 i686 i386 GNU/Linux

I just installed Oracle 10g.0.2 on it, and I have two instances on it. It is empty database, w/o releasing to public usage yet. SQL> show parameter sga

NAME                                 TYPE        VALUE


------------------------------------ -----------

lock_sga                             boolean     FALSE
pre_page_sga                         boolean     FALSE
sga_max_size                         big integer 776M
sga_target                           big integer 300M

SQL> So for 2 instance, I should only use 1.6G. But,

I have 16G of memory, but 14G were used. How are using it?
