Methods, systems, and articles of manufacture for allowing an update to an executable component, such as a logical partitioning operating system, running on a computer system without requiring a reboot (or IPL) of the computer system are provided. Processors or tasks executing in a portion of code being updated may be forced to a known or “quiesced” state (e.g., designated wait points) before applying the update. If any of the processors or tasks are not in their quiesced state, the update is not applied or may be rescheduled for a later time, in an effort to allow the system to reach the quiesced state.
