What is AutoSys AutoSys can be said as a Job scheduler which is basically a computer program used for controlling the unattended execution of a batch. Create Manage Jobs using Auto. Sys. Job scheduling with Auto. Sys. Auto. Sys is used for defining, scheduling and monitoring jobs. These jobs can be a UNIX script, java program or any other program which can be invoked from shell. Before starting we assume that user has already setup an Auto. Sys environment. This environment consists of autosys server and autosys client. Auto. Sys System components. Event server Auto. Sys database2. Event processor. Remote agent. Event Server. The event server is a Auto. AutoSys is used for defining, scheduling and monitoring jobs. These jobs can be a UNIX script, java program or any other program which can be invoked from shell. Sys database which stores all system information and events as well as all job, monitor, and report definitions. Sometimes this database is also called as 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. Event Processor. This is main component of the autosys system. This processes all the events it reads from dataserver. The event processor is the program, running either as a UNIX process or as a Windows service that actually runs Auto. Sys. It schedules and starts jobs. When you start the event processor it 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. 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. Basic functionality of Auto. Sys. Below is the diagram which explains the basic functionality, please check the explanation. Explanation. 1. The event processor scans the event server for the next event to process. If no event is ready, the event processor scans again in five seconds. The event processor reads from the event server that an event is ready. If the event is a STARTJOB event, the job definition and attributes are retrieved from the Event Server, including the command and the pointer full path name on the client machine to the profile file to be used for the job. In addition, for jobs running on Windows machines, the event processor retrieves from the database the user IDs and passwords required to run the job on the client machine. The event processor processes the event. If the event is a STARTJOB, the event processor attempts to establish a connection with the remote agent on the client machine, and passes the job attributes to the client machine. The event processor sends a CHANGESTATUS event marking in the event server that the job is in STARTING state. On a UNIX machine, the inetd invokes the remote agent. On a Windows machine, the remote agent logs onto the machine as the user defined as the jobs owner, using the user IDs and passwords passed to it from the event processor. The remote agent sends an acknowledgment back to the event processor indicating that it has received the job parameters. The socket connection is terminated. At this point, the event processor resumes scanning the event server database, looking for events to process. The remote agent starts a process and executes the command in the job definition. The remote agent issues a CHANGESTATUS event marking in the event server that the job is in RUNNING state. Torrent Dragon Medical Practice Edition Reviews. The client job process runs to completion, then returns an exit code to the remote agent and quits. Defining autosys job. There are various parameters to define autosys job. Starting from profile, timezone, start time, starting condition and so on. There are the two methods you can use to create job definitions 1. Using the Auto. Sys Graphical User Interface GUI. Using the Auto. Sys Job Information Language JIL through a command line interface. In this tutorial we will use JIL language to create autosys jobs. JIL stands for Job Information Language. Using this you can instruct autosys to save job definitions. This information saved in autosys database. You can also create a jil file which contains job definition. You can then pass this jil file to autosys. Essential attributes for defining job. Job Name. JIL Keyword insertjob. Name used to identify the job. Job Typea. JIL Keyword jobtype. The job type is one of job types command c, file watcher f or box b. Ownera. JIL Keyword owner. The job owner specifies whose user ID the command will be run under on the client machine. This attribute is automatically set to the user who invoked jil or the GUI to define the job, and cannot be changed except by the edit superuser. Other job attributes 1. The command attribute can be the name of any command, executable, UNIX shell script or batch file, and its arguments. This attribute specifies the client machine on which the command should be run. The start datetime dependencies attribute is a toggle, which specifies whether or not there are date, time, or both, conditions required for starting the job. The days of the week attribute specifies the days on which the job should be run. Sample jil file for command job echo. Job. jil. To add this job in atosys db.
