RE: KAIO and HPUX 11.0 with multiple Informix 7.31 instances

We have server running up to 10 instances with HP-11 and using KAIO. SERVERNUM has to be unique between instances.... post some onstat output like onstat -g seg onstat -u Wayne E Martin Informix Database Administrator Kmart Corporation -----Original Message----- From: pxllr@aol.com [mailto:pxllr@aol.com] Sent: Monday, January 29, 2001 6:43 PM To: informix-list@iiug.org Subject: KAIO and HPUX 11.0 with multiple Informix 7.31 instances Has anyone seen a problem with multiple informix engines on HPUX 11.0? My question is mainly that it appears our main production engine is set to use KAIO and it looks to me like it is configured to use the entire HPUX box (K260-4way with 2.5GB RAM). The onconf.dbname for each instance is set the exact same. This might be great for one instance, but whenever I try to bring up a second instance, I start getting bus error, core dump. HP is stumped, and I think it is a configuration problem in the engines. Also swapinfo is going from 11% to 89%. After a reboot, 11% then it goes up steadily till about 89% by Sunday, and I reboot Monday morning and start the process again. This may or may not be connected.
