Abstract
A networked system includes a master agent and at least one state agent. When upgrading the software of the master agent and the state agents, only the binary files at a shared location at the master agent are changed. To accomplish the change, a watchdog process at the state agent watches for the presence of a marker file at the master agent. The master agent produces the marker file if the master agent will accomplish a software upgrade. When the marker file is present, the state agent stops execution. The watchdog continues to monitor the presence of the marker file until the marker file is deleted at the end of the installation process. When the marker file is deleted, the state agent installs the new binary files associated with the software upgrade and resumes execution.
