Yesterday I configured an instance of IDS 9.3 on RedHat and changed the
shared libraries base address, so now I'm using over 2GB of shared
memory for Informix with one million buffers
echo 0xB0000000L > /proc/$$/mapped_base
su -l informix -c oninit -v
I also have an old SCO 3.2v5.0.5 with IDS 7.3, and I would really like
to use more memory for that instance, because I've been unable to use
more than 300000 buffers. Is there a way to change the shared libraries
base address on SCO 3.2? Maybe another trick to use more memory?
