Whenever I hear about z/VM guests "going to sleep" the first things out of my mouth are: - Do you have a z/VM performance monitor? What's it telling you about Elibible lists? Really, you need to get a monitor. No, really. - What are your z/VM SRM parameters? The defaults aren't good for Linux workloads. - How much real and expanded storage does your z/VM system have? That's not enough, get more. - How big is your Linux guest? - Does it really need to be that big? You should try shrinking it. - Why did you make it bigger? I told you to shrink it. - I'm closing this problem. Open a new one when you get a z/VM performance monitor. (I wish I could say this one.) I'm seriously considering starting to tell people that "If you don't have a performance monitor, you don't really have a performance problem." Someone at the z/VM and Linux T3 asked me if they could use that with their customers. I told them to go ahead. </vent> Mark Post ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
