Overview of AutoSys
In this series of articles, we take a look at AutoSys. AutoSys is an automated job control system for scheduling, monitoring, and reporting. In simpler terms, it is a workload automation tool. These jobs can reside on any AutoSys-configured machine that is attached to a network. An AutoSys job is any single command, executable, script, or Windows batch file. Each AutoSys job definition contains a variety of qualifying attributes, including the conditions specifying when and where a job should be run. As with most control systems, there are many ways to correctly define and implement jobs.
AutoSys Jobs
In the AutoSys environment, a job is a single action that can be performed on a valid AutoSys client machine. On UNIX, this action can be any single command or shell script, and on Windows, this action can be any single command, executable, or batch file. In addition, job definitions include a set of qualifying attributes.
Defining Jobs
Using AutoSys utilities, you can define a job by assigning it a name and specifying the attributes that describe its associated behavior. These specifications make up the AutoSys job definition. There are two methods available to create job definitions.
- Using the AutoSys Graphical User Interface (GUI).
- Using the AutoSys Job Information Language (JIL) through a command-line interface.
AutoSys Graphical User Interface
The AutoSys GUI allows you to interactively set the attributes that describe when, where, and how a job should run. The fields in the GUIs correspond to the AutoSys JIL sub-commands and attributes. In addition, from the GUI Control Panel, you can open applications that allow you to define calendars, monitors, and reports, and allow you to monitor and manage AutoSys jobs.
Job Information Language
AutoSys JIL is a specification language, with its own syntax, that is used to describe when, where, and how a job should run. When you enter the jil command, you get the jil command prompt, at which you can enter the job definitions one line at a time using this special language. When you exit the jil command-line interface, the job definition is loaded into the AutoSys database. Alternatively, you can enter the definition as a text file and redirect the file to the jil command. In this case, the jil command activates the language processor, interprets the information in the text file, and loads this information in the AutoSys database.
