I increased the memory and I it did not happen again. Also, in trying to recreate the problem I decreased the memory again and ran a small load of the database, but I have not experienced any problems so far. I could probably recreated the problem if I ran the full load.
If you make the Linux virtual machine small enough (say half of what z/VM has) then VM has no trouble to fit it in (actually when you add up all Linux virtual machines and the total is about half of what real storage is installed). Beyond that you need to tune VM settings. It would not happen immediately, but after some time when Linux has seen enough data to use the memory. While small Linux servers avoid this scenario, that does cause all kind of problems for the workload inside Linux because stuff will not fit. You can do a lot with proper tuning. This has been discussed often on the list in detail, but it might be easier to start reading the IBM Redbook SG24-6926 http://www.redbooks.ibm.com/abstracts/sg246926.html -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/ ---------------------------------------------------------------------- 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
