select bytes from v$sgastat where name = 'free memory' and pool = 'shared pool';

HTH

Thanks Hrishy

ggnanaraj,
Thanks man for your quick reply it helped m a lot. but i think query given by hrishy is more specific coz it gives correct free space and your query will give free space only in shared pool. When i queried
select * from v$sgastat;

i noticed...

large pool free memory 16777216
java pool free memory 117440512

they are the part of SGA . But i have not configured them just its a free space . Will it get used if need arises. like increasing any parameter.
