Error while starting KAIO threads

I have following configuration: 1. HP-UX 11.00 on rp7410 / 4x550MHz / 4GB RAM 2. Informix Dynamic Server 2000 Version 9.21.HC4 using raw chunks (no cooked files at all) 3.

Hi, > What might be a problem? Where should I start looking? Maybe at the things your message log tells you to look for? > 04:15:51 The chunk '/home/informix/databaselinks/tempdbs' > must have owner-ID "informix" and group-ID "informix". The origianal device files must have these attributes. Additionally they must have mode 660. Besides that, the async driver must be included in the HP-UX kernel (it isn't normally). The device file /dev/async must exist and have read/write-permissions for everybody. If you aren't using Informix mirroring the major/minor numbers for that device file are 101/0 - look at your machine notes. The user informix must have mlock-privileges (/etc/privgroup).

Where should I start looking? > > Dejan. To elaborate just a bit more on what Andreas said about configuring the async driver... * enable kernel async I/O: a. HP KAIO driver "asyncdsk" is installed and linked into the kernel. b. To ensure KAIO driver is up and running, check to see if /dev/async exists; if not, then run the following commands as root: # /usr/sbin/mknod /dev/async c 101 4 # chmod 0666 /dev/async c. # echo "informix: MLOCK" > /etc/privgroup # setprivgrp -f /etc/privgroup # getprivgrp -- should display: global privileges: CHOWN informix: MLOCK HTH, Paul Mosser
