There are a lot of reasons why it depends is the correct answer to this question. You can definitely reduce overhead on the VM layer by running multiple applications on a single Linux guest. When you have a few applications with a few dozen servers, it may make sense to have one appliction per

I'm wondering about this. I'm a z/OS person with some Linux knowledge. But we don't run Linux on z around here. In the Windows world, the mantra is generally One server, one function. On z/OS it is the opposite of one server, lots of functions. How does Linux, in general, stack up on this

If you're using the RPM (which Mark pointed out is the way to go), it looks like you'll need to install the other compat-libstd package (compat-libstdc++-33) i.e. not compat-libstdc++-295. You also need the libXp rpm. Here's the output of what each rpm provides (taken from RHEL 5): # rpm -qp

I take it you are not under VM, which would make all of this fun irrelevant because you can keep the same address virtually! I think what you need to do is mkinitrd and zipl to another disk but using a zipl.conf that has the appropriate dasd= parm. That is still an option in 2.6 even though
