I'd
set the shmmin to 1 and the shmmax to <machine memory
size>.
<FONT face=Arial color=#0000ff
size=2>
if it
were me, i'd probably have over-allocated something, so, i'd do an ipcs
-a
for my
"couple of databases" and make sure i had no more than two chunks
of
shared
memory allocated ( ignoring root stuff, of course). Not that
breaking
the
SGA into a few pieces is a crime against humanity, but....no positive
need
to do
it, either....

the
unit shmmax is measured in is OS page sizes as i recall, but...just RTFM
on
<FONT face=Arial color=#0000ff
size=2>/etc/system and it'll make it clearer than i could.

/etc/system parameters on Solaris 8
<SPAN

<SPAN

<SPAN
class=718075221-27022001> Recently I have setup a couple
8.1.6 databases on Solaris 8. The databases appear to function normally,
but when I shutdown either of them I receive
the following message in a trace file:
<SPAN
class=718075221-27022001>
skgm
warning: EINVAL creating segment of size 0000000004100000fix shm
parameters in /etc/system or equivalent
<SPAN
class=718075221-27022001>(the message is repeated several
times except for the segment size being
different)
<SPAN
class=718075221-27022001>
I
checked the /etc/system parameters and they are the same as some of my other
boxes (Solaris 6 machines running 4-6 databases each) and they seem to work
fine. Memory shouldn't be a problem on this machine since it has 4
Gb of RAM with only 2 databases up and running. Running 'top'
shows that plenty of memory is available also. Here are the /etc/system
parameters for Oracle....
