In the Linux world, I know of only 2 ways to use clusters:
1. with Oracle databases, as database servers
2. in supercomputing (Beowulf, OpenMosix, etc.)
In the OpenVMS world, there are shared-disk clusters, and it's buried
deep in the OS, so *any* program that uses the VMS RTLs, no matter what
it is (text editor, email, java, database, etc, etc), is cluster-
aware.
So if you are on NODE1 and it crashes, you fail-over to NODE2, and
continue from your last checkpoint. Of course, NODE2 is now 1/2 as
fast, since there are 2x as many users on it...
So, other than those 2 examples, how do you do clustering in Linux?
