some of the same can be used in linux... we run oracle on linux and solaris
and we use some of the same sysV mem settings. you are correct it will be some
trial and error...
for sure the shared mem settings can be applied (exmpl):
kernel.shmmax = 2147483648
kernel.shmmni = 128
kernel.shmall = 2097152
kernel.sem = 250 32000 100 128
sysctl.conf...

I've seen and have all the links I need to the "Veritas" tunning docs on their
WEB, however, I'm looking for someone that has been there done that and can say
under Linux 2.1 running as a dedicated Media Server; here are setting's that
give us the best performance.
There is a least someone ... no? If not , I'll invent the wheel and pass on
what I find out.
Thanks,

set shmsys:shminfo_shmseg=200
* END NetBackup recommended minimum settings
some params are no longer valid for sol9... im quite interested in what others
have set for FC lto2 drives for NUMBER_DATA_BUFFERS and SIZE_DATA_BUFFERS.
i also do some tweaks with /dev/udp and /dev/tcp (ie, changing window sizes
etc..)
