RE: /etc/system parameters on Solaris 8

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. <FONT face=Arial color=#0000ff

  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

  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....

  Does
  Solaris 8 require some of these parameters to be higher?  I tried looking   on MetaLink, but....well, you know that story.  Ask Ross Mohan for the   details on Metalink....
