While primary control of Qube Remote Control is the Supervisor, the Worker is responsible for making monitoring the remote host and executing jobs dispatched by the Supervisor. Like the Supervisor, once the Worker is configured, there is little need to return to its configuration.
Workers can be configured locally on the system or centrally from the Supervisor. One can configure all Worker parameters locally. However, with larger farms, the Worker configuration process can become cumbersome, so Qube is designed to allow for a minimal configuration local to the host, in favor of a centralized configuration on the Supervisor. The qbwrk.conf file on the Supervisor is configuration file is the most efficient place to all your Worker configurations. Since this file is located only on the Supervisor, it allows an administrator to define settings for many Workers in central location.
A Supervisor autodiscovery process is used by Qube as a means to quickly identify the Supervisor without any local configuration necessary. If the Supervisor isn't explicitly set in the Worker's configuration file, it will use autodiscovery to find the Supervisor host name and IP address. However that Supervisor and Worker must be on the same network subnet. Once it has that information it can then gather configuration from the Supervisor and continue the startup configuration process.
