1. Batch Processing in Dynamics AX

In batch processing, you create batch jobs to organize “batchable” tasks for processing, schedule and define the conditions under which the batch tasks are executed, add the tasks to a queue, and set them to run automatically on a batch server. After the execution is completed, the batch server logs the errors and sends alerts. For example, a batch job might involve printing reports, closing inventory, performing maintenance, or sending electronic documents using the Application Integration Framework (AIF)—at a specified time on a specified computer. When you use a batch job to process these types of resource-intensive tasks, you avoid slowing down the user’s computer or the server during working hours.

In the following sections, we explain how each of these batch processing concepts are put into action in Dynamics AX.

Dynamics AX Batch Concepts

Table 1 describes how standard batch processing concepts are represented in Dynamics AX.

Table 1. Batch Processing Concepts in Dynamics 2009
Batch ConceptIn Dynamics AX 2009
Batch frameworkAn asynchronous server-based batch execution environment. The environment is capable of executing multiple batch tasks within a batch job, in parallel, across multiple instances of the Application Object Server (AOS).

The Batch framework gives developers and administrators the flexibility to control the schedule and the order in which tasks are executed. For example, an administrator can set up a job to process invoices automatically at the end of every month on a specific AOS, and set up a different sequence of tasks depending on whether an earlier task succeeds or fails.

The Batch framework also provides transaction control, logging, and alerting mechanisms.
Batch taskA batch-enabled class. A class must be enabled for batch processing before it can run as a batch task, and any class that is batch-enabled can execute as a batch task. The Dynamics AX classes that are used for batch tasks are designated to run on either the client or the server. Tasks that run on the server can run automatically as part of a batch job, regardless of whether a client is open. However, tasks that run on the client must be run manually by using the Batch processing form.
Batch jobA complete process that achieves a goal, such as printing a report or performing the inventory closing process. A batch job is made up of one or more tasks.
Batch groupAn attribute of a batch task that allows the administrator to determine which AOS runs the job. Batch groups are used to direct batch tasks to specific servers. If a new task is created, by default it is assigned to an “empty” batch group, which is a valid batch group.
Batch serverAn instance of the AOS that processes batch jobs

Batch Framework Capabilities

As a system administrator or developer, you can use the new server-based Batch framework to create larger, more complex batch jobs than before. You can also monitor the status of batch jobs and control which AOS runs the batch job and at what time. The following list includes specific tasks you can do with the new Batch framework capabilities in Dynamics AX 2009:

  • Run server-based batch jobs using the security credentials of the user who created the job. Running the batch job under the credentials of the user who created the job provides the benefits of security isolation.

  • Create dependencies between batch tasks, and control the order in which the tasks are executed. The tasks in a batch job can run sequentially or simultaneously. You can set up a different sequence of tasks, depending on whether an earlier task succeeds or fails.

  • Set the time at which the batch job is executed, and specify which AOS executes the batch job. The servers in your environment might have different software installed or might be available at different times of the day. You can select the most appropriate server on which to run a batch job using the Batch Group attribute.

  • Create recurrence patterns for batch jobs. Some batch jobs need to be run on a recurring basis. For example, your company might need to process invoices automatically at the end of every month.

  • Monitor the batch job. You can ask for an alert to be sent when a batch job succeeds or fails, or just when it finishes.

  • Check the status, cancel, or review the history of the batch job. After a batch job has been processed, you can view its history, including any messages encountered while running the job.

Performance

Along with more complex and larger batch jobs comes the need for performance enhancements to the Batch framework. The Dynamics AX 2009 Batch framework provides parallel execution to improve performance for long-running processes.

Microsoft developers use the Batch framework as a foundation for many performance-critical processes, such as maximizing hardware scalability during data upgrade and maximizing posting throughput during journal posting. The white paper “Journal Batch Posting,” available at http://www.microsoft.com/downloads/en/default.aspx, describes many of the ways in which Microsoft uses the Batch framework.

Because it is a server-based component, the Batch framework enables you to design multithreading server processes in a controlled manner. By configuring the number of parallel execution threads, defining the set and order of tasks for processing, and setting the execution schedule, you can achieve greater scalability across your hardware. In addition, your batch tasks are running securely on a server, so you can process them without having a client open.

2. Common Uses of Batch Processing

Businesses typically want to create batch jobs to address the following kinds of needs:

  • To enable scheduling flexibility The Batch framework can perform periodic data clean-up jobs or run invoice processing on a regular schedule. To run invoice processing at the end of every month, for example, you could set up a recurring batch job that runs at midnight on the last working day of each month and selects the invoice processing job from the list of available jobs. You could then save the schedule (along with its batch job), and the system automatically picks up the job at the specified time and executes it without having to open the client.

  • To control task execution order With the Batch framework, you can develop a workflow or perform a complex data upgrade in an order you choose. When creating a new batch job and adding tasks to the job, you can set up dependencies between the jobs and create a dependency tree that ensures that certain tasks run in sequence while others run in parallel.

  • To enable different processing if a particular task succeeds or fails Task processing based on decision trees can help you implement a reliable way of processing data. The Batch framework allows developers or system administrators to set up dependencies between tasks such that different tasks are executed depending on whether a particular task succeeds or fails. The system administrator or developer can also set up alerts to be notified if a job fails for any reason.

  • To improve performance using multithreading Multithreading ensures that your processor’s capabilities are fully utilized, which is particularly important for long-running processes like inventory closing. You can gain additional performance enhancements by breaking a process into separate subjobs and executing them against different AOS instances, increasing throughput and reducing overall execution time.

  • To gain advanced logging capabilities The Batch framework lets you see errors or exceptions thrown during the last run of the batch and to see how long a process takes to execute. Advanced logging capabilities are also useful for performance benchmarking and security auditing.
