Autosys system components are:-
• Event Server
• Event Processor
• Remote Agent

• Event Server (or Autosys Database)
o Data Repository that stores Autosys system information,events and job definitions.
o The Autosys Db is termed ‘Data Server’ which describes a server instance

• Event Processor

o Interprets and processes all the events it reads from the Autosys Database

o A program that actually runs Autosys

o Scans the database for processing events. Checks if the events satisfy the starting conditions of the job and the determines the actions

• Remote Agent

o Temporary process started by the event processor to perform a specific task on a remote machine

o It starts the command specified for a given job, sends running and completion information about a task to the Event Server

o If it is unable to transfer the information, it waits and tries until it successfully communicates with the Db

Interaction Between System Components

• Step1: From the Autosys event server(that holds the Events and Job Definitions info),the Event Processor reads the new event,checks for the condition,reads the job definition and determines the actions.

• Step2: The Remote Agent receives the instructions from the Event Processor

• Step3: The Remote Agent performs resource checks,ensuring minimum specified number of processors are available and then initiates a child process that runs the specified command

• Step4: The command completes and exits,with the Remote Agent capturing the command’s exit code.

• Step5: The Remote Agent directly communicates the event(exit code,status) to the Event Server.
