Hi,

in theory, 32-bit word size can address max. 4Gb memory space.

I guess total 1.7GB restriction is for HP-UX (32-bit). As I know, you can have an SGA of 1 Gb max. and 1.7Gb total on HP-UX (32-bit).

Solaris and HP memory managements are different.

if you dont change sgabeg, maximum SGA size in solaris is 1.73Gb. if you change sgabeg, it's up to 3.7Gb. New additional memory is taken from where PGAs reside.

Since sgabeg is relative address in each segment, you can have many sgabegs for many segments. I guess, you may exceed 3.7Gb restriction for solaris in total.

regards...
