These jobs can reside on any Unicenter AutoSys JM - configured machine that is attached to a network. A job is any single command, executable, script, or Windows batch file. Each 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. It is likely that the way you utilize Unicenter AutoSys JM to address your distributed computing needs will evolve over time. However, before you install and use Unicenter AutoSys JM, it is important to understand the basic system, its components, and how these components work together. This chapter provides a brief overview of Unicenter AutoSys JM, its system architecture, and features.

Introduction 1 1. 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. For information on defining, running, managing, monitoring, and reporting on jobs, see the corresponding chapters in this guide. Defining Jobs Using 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 job definition.

Graphical User Interface The GUI lets you interactively set the attributes that describe when, where, and how a job should run. In addition, from the GUI Control Panel, you can open applications that lets you define calendars, monitors, and reports, and let you monitor and manage jobs.

Job Information Language 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 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 database. The following figure illustrates the Unicenter AutoSys JM system components in a basic configuration. In addition, this figure illustrates the communication paths between the components.

Event Server The event server or database the RDBMS is the data repository for all system information and events as well as all jobs, monitor, and report definitions. Event server refers to the database where all the information, events, and job definitions are stored.

Occasionally, the database is called a data server, which actually describes a server instance. That is, it is either a UNIX or Windows process, and it is associated data space or raw disk storage , that can include multiple databases or tablespaces. Introduction 1 3. Some utilities, such as isql Sybase , let you specify a particular server and database.

This feature provides complete redundancy. Therefore, if you lose one event server due to hardware, software, or network problems, operations can continue on the second event server without loss of information or functionality. For various reasons, database users often run multiple instances of servers that are unaware of the other servers on the network.

Event Processor The event processor is the heart of Unicenter AutoSys JM; it interprets and processes all the events it reads from the database.

It schedules and starts jobs. After you start it, the event processor continually scans the database for events to be processed. When it finds one, it checks whether the event satisfies the starting conditions for any job in the database.

Based on this information, the event processor first determines what actions are to be taken, then instructs the appropriate remote agent process to perform the actions. These actions may be the starting or stopping of jobs, checking for resources, monitoring existing jobs, or initiating corrective procedures. This second processor should run on a separate machine to avoid a single point of failure.

The shadow event processor remains in an idle mode, receiving periodic messages pings from the primary event processor.

Basically, these messages indicate that all is well. However, if the primary event processor fails for some reason, the shadow event processor will take over the responsibility of interpreting and processing events.

Remote Agent On a UNIX machine, the remote agent is a temporary process started by the event processor to perform a specific task on a remote client machine. On a Windows machine, the remote agent is a Windows service running on a remote client machine that is directed by the event processor to perform specific tasks. The remote agent starts the command specified for a given job, sends running and completion information about a task to the event server, then exits. If the remote agent is unable to transfer the information, it waits and tries again until it can successfully communicate with the database.

Introduction 1 5. Note: In this example, the three primary components are shown running on different machines. Typically, the event processor and the event server run on the same machine. Then the event processor reads the appropriate job definition from the database and, based on that definition, determines what action to take.

As soon as the remote agent receives the instructions from the event processor, the connection between the two processes is dropped. After the connection is dropped, the job will run to completion, even if the event processor stops running. The remote agent performs resource checks, such as ensuring that the minimum specified numbers of processes are available, then forks a child process that will actually run the specified command.

The command completes and exits, and the remote agent captures the command s exit code. The remote agent communicates the event exit code, status, and so forth directly to the event server.

AutoSys: A Beginner’s Guide to Master AutoSys Workload Automation

AutoSys is a job scheduler used for defining jobs, which helps in controlling and monitoring processes. The jobs can be created using batch programs or UNIX scripts. For setting a job, you need access to AutoSys prompt. On a Windows machine, you can define the job in the command prompt, whereas, on a Linux machine you have to define a job using the terminal. JIL is the standard scripting language used for defining AutoSys job, like all programming languages , JIL also comes with some predefined keywords and attributes. The key thing while defining a job in AutoSys is that you need to figure out the conditions and then define the job using the subcommand and attributes, and once you are done, you need to schedule a time during which the job is going to get triggered.
