Intershop Order Management (IOM) has the ability to configure and run time based jobs with the help of the integrated Quartz job scheduling library. This document describes the basic concepts. The target audiences are partners, consultants and developers.
In a nutshell, the main idea behind job scheduling is:
in order to automate processes.
|IOM||The abbreviation for Intershop Order Management|
|Quartz||An open source job scheduling library|
The following section lists the main tasks of Quartz jobs in the context of IOM.
The IOM uses asynchronous business processes that are initially triggered by:
For various technical reasons, such business processes can abort unexpectedly. The jobs are responsible for resuming the processing of pending business processes (or single tasks of them), in order to finish them.
For details please see the jobs of the POST_PROCESSING_* and the TRANSMISSION_RETRY job groups in Reference - IOM Quartz Jobs.
There are jobs, that trigger the import resp. export of various data (e. g., articles, customers, orders).
For details please see the jobs of the IMPEX_* job groups in Reference - IOM Quartz Jobs.
There are jobs, that trigger simple business operation tasks like sending payment reminder e-mails or checking for expiring credit cards, etc.
For details please see the jobs of the BUSINESS_OPERATION_* job groups in Reference - IOM Quartz Jobs.
There is a single job in the VALIDATE_PCM job group, that triggers the validation of existing process control configurations.
For details please see the jobs of the VALIDATE_PCM job group in Reference - IOM Quartz Jobs.
By the default configuration, a single job in the JOB_FRAMEWORK job group triggers the IOM Job Framework.
In order to use the Quartz job scheduling provided by the Intershop Order Management (IOM) at least two configuration files are required within the $VAR/etc folder. These are:
|quartz-cluster.properties||basic scheduling configuration|
|quartz-jobs-cluster.xml||detailed job and trigger configuration|
By default, after the initial setup of the IOM, both configurations already exist with a working set of configurations.
The basic scheduling configuration is required to define a single scheduling instance. The corresponding file must be named quartz-cluster.properties, has to be located in the OMS_ETC directory and is used after the startup of the bakery.control-app-$OMS_VERSION.ear artifact to instantiate the scheduling instance. By default, that single clustering scheduling instance is configured to use the detailed job and triggering configuration file (quartz-jobs-cluster.xml) to schedule a working set of time-based jobs. For further details please see the Quartz Configuration Reference.
