SuSE 8.2 is by default maxed to 4 GB (if I remember that number right,
long time since I ran this release) so Kernel has to be tuned, better:
go to a more current SuSE version, because 8.2 is out of patches since
several years now.
As already said, you need a 64Bit Informix release

are you running 32-bit IDS or 64-bit IDS?

"Mostly, when you see programmers, they aren't doing anything. One of
the
attractive things about programmers is that you cannot tell whether or
not
they are working simply by looking at them. Very often they're sitting
there
seemingly drinking coffee and gossiping, or just staring into space.
What the
programmer is trying to do is get a handle on all the individual and
unrelated
ideas that are scampering around in his head."

Subject: How can I use 32Gb of ram in IDS 9.4 [20124]
I have IDS9.4 on Suze 8.2 on a IBM 445 with 8 CPU and 32 Gb of ram
How Can I use more of the Ram ?
I have tried playing around with buffers but if I go past 280000 the
instance
dosn't come on like and complains :

parameters (e.g. MAXMEM)
