Apply operating system patches or hardware updates

The operating system (OS) administrator is responsible for applying OS patches.

The application of an OS patch may require a restart of the server. Because of that, there are some considerations regarding the Service Manager systems.

If Service Manager is installed as a horizontally scaled environment, it may be shut down on a host for maintenance, while it is still accessible on other hosts. The only requirement is to not shut down all hosts concurrently, which keep the JGroups cluster of the Service Manager servlets running.
