JAMS Terminology

Follow

Job: An individual process that contains a number of defined Properties to ensure it runs at the correct time and under the right set of circumstances. Essentially, every component in JAMS supports or controls how a Job is defined or executed.

Setup: The simplest way to sequence a stream of Jobs. All Setup Jobs contained within a Setup are assigned a Step Number and are run based on the order of that step. If more than one Setup Job is assigned the same Step Number, they are run in parallel.

Parameter: A component of a JAMS Job, Folder or Execution Method. Parameters are similar to a JAMS Variable but remain local to a Job, while Variables are globally defined throughout the JAMS environment.

Variable: A global value that can be used by any JAMS definition to easily pass data between objects. Variables can be used to override default values for Parameters.

Execution Method: Defines how a Job executes within the JAMS environment. JAMS ships with dozens of predefined Execution Methods that run Jobs on Windows, Linux, UNIX, OpenVMS, and REXEC compliant operating systems.

Precheck Job: A Job linked to a parent Job or Setup. When a Precheck Job is Submitted, the parent Job or Setup remain in a Pending state until the Precheck Job completes successfully. JAMS Submits the Precheck Job only when the parent Job or Setup are ready to run.

Dependency: A defined precondition for running Jobs and Setups. Within JAMS, all Dependencies must be fulfilled before a Job or Setup can run. In additions, Notifications can be triggered if a Dependency is not met within a defined timeframe.

Recovery Job: A Job linked to a parent Job or Setup and Submitted only when the parent Job or Setup completes within a defined Severity level. Recovery Jobs are used for a variety of reasons, from resetting data within databases to creating flag files.

Notification Job: A Job linked to a parent Job or Setup and Submitted only when the parent Job or Setup completes within a defined Severity level. Notification Jobs are similar to Recovery Jobs, and are used to quickly pass data through the API or send Notifications to 3rd parties.

    would be helpful to know what the job flow might be if you set retry to say 1 and set a recovery job. Does it run the recovery job and then retry? Does it ignore the retry if there is a recovery job?

    Hello Tom,

    The recovery job does not run until the job has failed for the last time. Otherwise, the job is restarted based on the retry count and retry interval and when the number of retries is used up, the recovery job runs.

    The job is technically not considered "complete" or "failed" until it has failed for the last time.
