hi

with patches (not patchsets) you have several options

  1. full outage, that is shutting down all instances and you patch in a node the patch will be propagated to the rest of nodes
  2. partial outage, you can choose patch 5 nodes per time, apply in one of 5 nodes the patch is propagated to the other 4 automatically
  3. rolling upgrade, one node per time

quite a few patches supports rolling upgrade nowdays, with rolling upgrade patches you can choose from these three methods otheriwse the only choice is method 1

thanks
