Background processing reduces the load on dialog work processes by scheduling regular activities to run in the background. A background job consists of one or more steps, which can be an ABAP program, external command, or external program. Jobs are assigned priorities and can be triggered by time or event. The Job Wizard provides an easy way to define a job with general information and start conditions. Job monitoring displays job status and logs.
This document outlines the minimum steps to set up a part workflow in a factory management system, including creating a part master by entering identifying information like the part number and revision, then setting the part master status to current; next, a quality control plan is created by selecting a plan owner and setting the QCP status to current, with at least one specification added.

Developing for Remote Bamboo Agents, AtlasCamp US 2012Atlassian
Brydie McCoy, Java Developer
As more and more peoples' building demands grow, they expand from building everything locally to a distributed building system or the elastic cloud. And for OnDemand the elastic cloud is the only option. Unfortunately developing plugins for remote/elastic agents has its own set of gotchas. Most plugins written for Bamboo do not work properly on remote agents. This talk will cover the core principles of developing for remote agents, what you can and can't do, as well as more advanced topics such as data transfer and communication between the agent and the server.
one of the most interesting project I have ever worked on was a migration project that needed to be handled as a batch process, in this slides we will have an overview of the challenge we had, the choices, why we chosed Spring batch, and have an overview of Spring Batch capabilities, in less than 15 minutes.
The document discusses Oozie 3.0 features including the introduction of bundles to define and execute a set of related coordinators together. It describes how bundles improve scheduling and control of workflows. It also covers enhancements to scalability such as throttling active jobs and improved usability like redesigning coordinator job statuses. Future plans include increasing scalability through push-based data checks and improving adaptability, monitoring, load balancing, and usability.

CA-7 is an online, real time, interactive system which automatically controls, schedules and initiates work according to time-driven and/or event-driven activities. It provides online scheduling facility and selects, submits, tracks, and analyzes the execution of jobs. The system uses different queues (Request, Ready, Active) to manage jobs as they move through the scheduling and execution process, and various commands allow users to view job status and histories or make changes to jobs in the queues.
CA-7 is an online, real-time system that automatically controls, schedules, and initiates work according to time-driven and event-driven activities. Jobs can be scheduled through batch cycles run in a specified order or triggered by the completion of other jobs. Jobs enter the CA-7 request queue and move to the ready queue once requirements are met, then to the active queue once resources are available to run. Operators can cancel, force complete, or restart jobs as needed from the different queues.

Editor's Notes
Dialog work processes are intended for dialog processing. For this reason, the duration of a dialog step is limited. Background processing is intended for operations that require a longer time to run. Background processing is also suitable for activities that are scheduled to run regularly, for example database backups or financial evaluations.
A background job consists of one or more steps. A step can be: An ABAP program An external command An external program Each job is processed without interruption by a single background work process. A job can be triggered to run: At a predefined date and time At the occurrence of a predefined event Background jobs can be prioritized as: Class A (high priority) Class B (medium priority) Class C (low priority) Jobs allocated to target servers have higher priority than untargeted jobs.
To define a new job, use transaction SM36 . From Release 4.6A, you can use the Job Wizard to define new jobs as follows: Specify job name, class, and optional target server Define a job step (a step can be an ABAP program, external command, or external program) Add further steps (if necessary) Start condition (time or event based) Complete the definition The Job Wizard allows you to go back and make changes at any point during the definition process.
The start conditions of a job can be time based or event based. Time based : Immediate At date/time On a chosen workday (defined as a certain workday per month) All time-based start conditions can be periodic. That is, a job can be performed at regular, defined time intervals. Days that are not workdays can be treated as exceptions. Parameter rdisp/btctime specifies the time interval of the job scheduler. Event based : After event (optional parameters can be used to further specify events) These can be periodic. That is, the job can be triggered every time the event occurs. After job (this can depend on the status of the previous job) At change of operation mode (for example, between day and night) Parameter rdisp/btcname specifies which application server handles events triggered from within R/3.
A job step can be any one of the following. ABAP program Any ABAP program that generates a list can be used as a job step. If the program includes a selection screen, you must create a variant before you can let it run in the background. A variant is the result of assigning definite values in the fields that appear in the ABAP program selection screen. The list is stored in the R/3 spool system. When you define the step, you can set the print parametsrs (for example, output device) and a spool list recipient (this is a SAPoffice addressee). External command An external command is any non-R/3 program, script, or command that is executed at operating system level. Since these commands are defined in R/3 by the system administrator, the administrator use R/3 authorizations to limit the scope of the commands and their availability to R/3 users. External program An external program is also any non-R/3 program, script, or command that is executed at operating system level. The system administrator has not previously defined these programs in R/3 and no check is made for critical or dangerous programs. In the latter 2 cases, the programs are called up at the operating system level by program sapxpg . The programs are processed synchronously (job waits for termination of the external program) or asynchronously (next job step is processed immediately). The output (stdout and/or stderr) of the external program can be taken up in the job log.
The job status can be any of the following: Scheduled : job is created but has no start condition Released : job is completely defined and waiting for selection Ready : job has been selected for execution Active : job is being executed by a background work process Finished : the entire job has been successfully executed Canceled : job terminated with problems As long as a job has status scheduled or released , it can still be changed. If execution of a job has already started, its progress can be monitored in the job log. If the job contains ABAP programs, their output is stored in spool lists. To create the steps of a new job from an existing job, choose Copy .
Typically, customers require more dialog processes during the day and more background processes during the night. To adjust the proportions of the various R/3 work processes to suit different phases of system activity, you can: Maintain the instance profile and restart the system (for unusual changes) Define operation modes and use the operation mode switch (for daily changes) Operation modes optimize system resources for different phases of system activity. Operation mode switching reconfigures your R/3 System dynamically, so you do not need to change the instance profiles for your server and you experience no system downtime. An operation mode configures the use of resources for all the instances in your R/3 System based on: The services or work processes you need The time interval you choose
To monitor jobs, call transaction SM37 . From Release 4.6A, the initial screen offers an extensive range of selection criteria. For example, you can select jobs by specifying one of their steps. To list event-based jobs, you must specify an event. This job list presents the user selection at the top of the screen. The ABAP List Viewer (ALV) is used to display the list and enables you to store multiple display variants. From the job overview, you can navigate to various detailed job-related views: The job log enables you to monitor the progress of a job. The spool list contains the output of ABAP programs, if any. Job details include the job definition, execution time, and background work process number.
