I don't know if anyone replied yet, but I will try and answer this. Depending on your unix flavor, the nice values will be different. Linux nice values are between -20 (highest priority) and 19 (lowest priority), with a default of 0. For hpux, the values are from 0 to 39, with a default of 20. I don't know what the aix values are. The syntax for the nice and renice commands will be slightly different for each platform.
The priority value that shows in the "ps -l" under the PRI column is not the same as the nice value, which shows under the NI column. The priority value (I think) is the order in which the process will get timeslices from the cpu(s). On a U2 system, there are many things that I would check before messing with nice values. In theory, even if you lowered the priority of a phantom process, you could clog up regular processes that are waiting on that phantom process to release a lock. And since you just lowered the priority, it's going to take longer than usual to release. The only occasion where I had to adjust the nice values was for some overnight reports. No locking, no writes, etc, Hope that helps. -----Original Message----- From: Jonathan Leckie [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 03, 2004 7:13 AM To: [EMAIL PROTECTED] Subject: [U2] Priorities for Unix udt processes Does anyone have any experience of what the "nice" and "priority" values should be and how they can be changed? -- ************************************************************************ * This message has been scanned for viruses and dangerous content by * Blairs of Scotland MailScanner, and is believed to be clean. * * This email and any files transmitted with it are confidential and * intended solely for the use of the individual or entity to which they * are addressed. * * If you have received this email in error please notify us at Blairs * of Scotland via email at [EMAIL PROTECTED] ************************************************************************ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/ ------- u2-users mailing list [EMAIL PROTECTED] To unsubscribe please visit http://listserver.u2ug.org/
