Robert

You have upgraded the server but not changed Informix?
SHMVIRTSIZE seems high, but I am unfamiliar with your platform and
application. Increasing BUFFERS would have been a better start point.

Do you have an issue with CPU, disk IO or memory on your server?
Does the application run on your server or only Informix?

Return
onstat -p
onstat -g seg
onstat -d
onstat -m
onstat -D
onstat -g iof

Okay here the machine data and onconfig:
The machine is a Compaq True 64 Unix V4.0 1229 alpha with 4 CPUs and 4
GB
mainmemory.
The only changes what we make is what stand in the releasenotes:
shmmax = not change (2147483647)
shmmni from 512 to 2048
shmseg from 150 to 512
semmni 400 (not changed)
semmsl 1600 (not changed)
semopm 400 (not changed)
semume 400 (not changed)

maxdsiz ( max-per-proc-data-size ) should change to 9223372036854775807
but
kernel let max 4398046511104
maxvas (vm-maxvas) from 2048000000 to 9223372036854775807
per-proc-adress-space (per-proc-address-space) from 2147483647 to
4398046511104
max-per-proc-address-space (max-per-proc-address-space) from 2147483647
to
4398046511104

onconfig are the same than before (temporary we change SHMVIRTSIZE from
1100000 to 3317760 but the admin befor make to smal swap space and we
get
problems so i turn this parameter back. now i put one more disk inside
and
make now biger swap space. (more than double mainmemory)
