As you know, Solaris 8 boots with 64 bits kernel as default when running on
E6500/E10K. I would like to hear your opinion on booting 32 bits kernel with
theses architectures.
An Oracle tech recommended to boot with 32 bits kernel for Oracle 8i
(8.1.7.4) 32 bits to perform better.
Here is his statement :
"Solaris 8 OS 32bits with Oracle 8i 32bits will perform well for you
application. There is no reason to run Solaris 8 64bits with Oracle 8i 64
bits, except when you have to exceed 32 bits limits".
I could easily understand that Oracle 32bits is sufficient and Oracle 64
bits only necessary when you need very large SGA or such 64 bits-related
things.
But for Solaris 8, I though that 64 bits kernel was recommended and
performed better for all UltraSparc2/UltraSparc3 servers. If not the case,
why would Solaris boots the 64 bits kernel as default ? Is this
necessary/better to boot 32 bits kernel when no 64 bits apps are running ?
Any opinion appreciated.
