Getting started with Feature Pack for Modern Batch

The major components of the batch include the command-line interface, Enterprise JavaBeans™ (EJB) interface, web services interface, job scheduler, and grid endpoint.

The following diagram shows the major components of batch. The batch components in the diagram include the command-line interface, EJB interface, web services interface, and Job management console. These components each communicate with the job scheduler. The job scheduler has a job database that contains all the jobs. The job scheduler in the diagram communicates with two node endpoints, while an application server that is doing transactional work runs on another node.

The job management console provides a graphical user interface (GUI) with which you can perform job management functions. Most of the function from other interfaces is also available from the job management console.

With the command-line interface, you can submit and control the batch jobs in the system. The enterprise bean and web services interfaces provide similar function to both Java™ Platform, Enterprise Edition (Java EE) and non-Java EE programs through programmatic interfaces. The administrative console provides a graphical user interface (GUI) with which you can configure the job scheduler, and view the location of endpoint servers.

Batch administrators and submitters can use the job management console to view, manage and perform job-related actions that include submitting a job, viewing of jobs, canceling or suspending a job, and resuming a suspended job.

The job scheduler accepts and schedules the execution of batch jobs. It manages the job database, assigns job IDs, and selects where jobs run.

The grid endpoints are application servers that are augmented to provide the runtime environments needed by batch applications.
