Hello all,
One of the database servers that I am currently working on is
a Sun 6500, running Solaris 2.7. It's a fairly large machine,
with 20 gig of memory. It's being used for development and testing
for multiple applications.
When I began installing our particular versions of Oracle (7.3.4.5
and 8.1.7) on the box, I noticed that there were several tunables
settings in /etc/system that I had not seen on Solaris boxes
previously. Is anyone familiar with the settings that I have
listed below? I have placed an <---- to the right of the tunables
in question. Could they perhaps be applicable to an HP-UX server?
So far I've only worked on Sun, AIX and Linux servers. The
shop where this server is located has been primarily HP-UX in
the past, so I thought that these might be legacy settings.
On Solaris, I've heard that it isn't a good idea to fool around
too much with tunables if it isn't necessary. Portions of the
kernel are "dynamic", and unneeded settings could limit OS operations.
Some of the typical Oracle settings don't look optimal either,
for example semmns=15000!!, but that is an issue for another
time.
Any info would be greatly appreciated,
Lou Avrami
