hi all

i createed a database in oracle 10g & using the mman feature that 10g includes.

I put statistics_level to all
and sga_target has also enough size.

but when I m trying to see the size of sga components in v$parameter, it shows me 0 for all the components. As far as i know, 'mman' automatically decide the size of sga component as per the situation, but it should be given some size to all components, then why not it shows
