Each adTempus installation can operate in one of three Engine Modes: Standalone, Master, or Agent.
If you are not using the Distributed Scheduling features of adTempus, you will use Standalone mode. If you are using Distributed Scheduling, you will have one Master computer and one or more Agent computers.
The Engine Mode is selected during installation but can also be changed after installing using the Engine Mode utility.
In Standalone mode, Distributed Scheduling is not used. Distributed Scheduling options are not available in the user interface.
However, you can still create links between jobs on multiple computers using the Job Control Action and the Job Condition.
In Master mode, adTempus can run jobs on the host computer and on remote computers where adTempus is running in Agent mode.
In Agent mode, adTempus can run jobs sent to it by a Master computer. An Agent can also be used just like a regular adTempus installation: you can connect to it with the Console and schedule jobs that are not controlled by the Master.
When you connect to an Agent using the Console, you can view distributed jobs, but you cannot modify them. All changes to these jobs must be made on the Master.
An Agent can only be the Agent for one Master. Once a Master has connected to an Agent, that Master owns the Agent, and no other Master can connect to it.
