Andre, I am not sure what you mean by "more KAIO to the engine". However, IBM recommends that the following KAIO parameters be set based on your number of disks. MINIMUM number of servers = 5 * (# of disks) MAXIMUM number of servers = 10 * (# of disks) These values are significantly higher than the default settings. They can be viewed and changed in the "smitty chgaio" panel. Rick -----Original Message----- From: Andre Ngo To: informix-list@iiug.org Sent: 3/17/00 3:51 PM Subject: KAIO in AIX Hi all!!! I came to a deadlock tying to figure this one out. Is there a way to add more KAIO to the engine? We are currently using Informix Dynamic Server 7.31.UC3 installed on in AIX 4.3. Thanks!
