This is the environment that we work in. z/VM 5.2, a couple z/OS (1.4 in production, going to 1.7 RSN), several test z/OS (some 1.7, some 1.8, some 1.5 - don't ask), 600+ Linux virtual servers. I would say we have an outstanding problem related to 5.2, but not related to running z/OS and Linux on the same hypervisor. Our problem is a load-related performance problem and involves DB2 for VM. It's a fairly specific to some unique aspects of our environment and not related to running both z/OS and Linux on the same z/VM. There were some significant memory improvements in 5.2 for handling the 2GB bar. It's currently on a z900, going to z9 at the end of the year. > >Mark /ahw ---------------------------------------------------------------------- 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
