Try this:

in file /etc/privgroup

groupid MLOCK


The group id should be the group that the owner of the Informix binaries is in.

This is based on my experience with Oracle and Software AG Adabas. The error message suggests to me that this situation may be similar.

Maybe not. Pete Randall runs Informix, maybe he'll post in.

setprivgrp informix MLOCK

Also, check out the release notes for informix:

$INFORMIXDIR/release/en_us/0333/IDS_7.3

and look for /dev/async

mknod /dev/async c 101 0
chmod 666 /dev/async

( These 666 permissions may be insecure. Once you have KAIO working you could try changing them to 660 together with ownership of informix:sys )

Then vi /stand/system and add drivers asyncdsk and asyncdsk_included, or use sam to add them in. Reb-build the kernel and reboot.
