Yeah. It still comes up useful if you have some very complex Apache configurations or WAS (Apache + some other ugliness) apps, but as you say, one app, one host tends not to be all that interesting (unless you get into the threading issues, and most business apps don't have that level of parallelism). ---------------------------------------------------------------------- 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 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
