Shares software installations are (a) only possible if you're using a
cluster file system (so if your cluster storage of choice is, say, raw
or ASM, then forget it) and (b) prevent you from doing rolling
upgrades (which are problematic anyway, it has to be said). Since
there's only one installation, you patch it -and if the patching
requires databases to be stopped, they all have to stop for the
duration. On the other hand, of course, you only have to patch once
and not 8 times, so it's a case of swings and roundabouts.
