You can query a patch to see if it's online patchable:
$ opatch query -is_online_patch 9974223

Patch is an online patch: false
OPatch succeeded.
I think currently almost all patches are still offline (old, non-online) patches. But the technology is already there. The first time I heard of it was at an IBM AIX seminar where they showed hot patching of part of the AIX operating system. The concept is great and may not be that difficult to implement.

Thank you. Document 761111.1 is a good one!
But this statement:
"Online patches should be used when the patch needs to be applied urgently and a downtime cannot be scheduled. IMPORTANT: It is strongly recommended to rollback all online patches and replace them with regular (offline) patches on next instance shutdown"
makes me feel that online patching is not as useful as I thought.
