Raja,
if i do what you do..the value is same.
i am not sure if you said the value between v$sgastat and v$sga is
different.

SVRMGR> select sum(value) from v$sga;
SUM(VALUE)
----------
  64046072
1 row selected.
SVRMGR> select sum(bytes) from v$sgastat;
SUM(BYTES)
----------
  64046072
1 row selected.
SVRMGR> 

Warm Regards,

Hello gurus,

I am not able to understand 1 thing:-

1. If I do :-

select sum(bytes) from v$sgastat;
it gives me the SGA as :- 35041712

2. But if I do :-

select sum(value) from v$sga I get:-  35059816

There is a difference of 18104 between 2 figures.

Which 1 should I trust? which gives me the correct value of SGA?

thanks 

rdgs,

raja
