Given that you don't want the total of all of your SGAs to be more than 1/3
to 1/2 of your physical memory (various people give various percentages, but
the principle is the same), you must have a pretty big machine there, else
you'll end up thrashing yourself to death on  OS page swaps.

Hi!

Oracle 9.2.0.4 on AIX 5.2.
I'm thinking of resizing my buffer cache >2GB and max_sga_size > 4GB.=20
Did anyone saw any bugs  or problems related to this issue?

TIA,
Sonja
