When do "pending" patches finally get applied?

Went into updates.sun.com and applied a patch to a system. I see in /var/sadm/spool that the jarball was downloaded but has not been applied.If the patch is within the patch policy, when will it be applied?

Both Update Manager and the agent that carries out commands from the Sun Update Connection use a patch policy of standard. This overrides the policy stored in patchpro.install.types. So any patch not of type standard is pending install until the system is restarted using either init or shutdown. You can see which patches are pending install on a restart on the client be looking at the contents of /var/sadm/disallowed_patch_list.

Makes sense, that explains some of the behavior I've seen.Another one then, are some of the patches applied on the way down as well as on the way back up or is it just one or the other?If it's both, how is the runlevel that it will be installed in determined?

All of the "restart required" patches are installed on the way down.-Dave
