Execution Methods

An Execution Method defines how a Job executes within the JAMS environment. JAMS includes dozens of Executions Methods to run Jobs on Windows, Unix, Linux, OpenVMS, or any operating system supporting connections using SSH. The Execution Methods are set up so they can be used with Job Definitions without any additional configuration. An Execution Method is associated with each Job Definition.

You can also create a new Execution Method by using an existing one as a template. It is recommended that you apply any modifications or customizations to a new Execution Method rather than an existing Execution Method. This helps to ensure any existing Jobs are not impacted. It also helps to ensure any customizations are not affected by an upgrade. For example, you can add a Parameter or a Job Property to an Execution Method and all Jobs that reference it will have the set Parameter or Job Property.

You can also create and customize your own Execution Methods. This is useful if you want to create an Execution Method that uses another programming language, such as Perl or Python. Creating a custom Execution Method is a two-step process that includes creating the Execution Method, and then modifying its properties. Both are described in detail below.

Execution Methods screen

The Execution Methods screen lists all the available Execution Methods in JAMS. Each Execution Method displays the following:

• Method Name - This is the unique identifier for the Execution Method.
• Description - This reference property is used to summarize the Execution Method definition.
• Last Changed - This property displays the date and time this Execution Method parameter was last modified.

Creating a New Execution Method

1. Click Execution Methods from the Shortcuts menu.
2. Click +.
3. In the Name field, enter a name for the Execution Method.
4. In the Base Method field, select an existing Execution Method that is used as a template.
5. Click Ok.
6. Click the Parameters tab to add a Parameter.
7. Click the Template tab to add any processing for the Execution Method.
8. Click the Properties tab to review and modify any Properties that are specific to the Execution Method.
9. Click the Job Properties tab set default values for certain Properties that are inherited by the Job Definition.
10. Click Save and Close.

Modifying an Execution Method

To make changes to an existing Execution Method, open its Execution Method Definition dialog from the Execution Methods View.

1. Click Execution Methods from the Shortcuts menu.
2. Double-click an Execution Method.
3. Modify the Execution Method, Parameters, Template, Properties, and Job Properties as desired.
4. Click Save and Close.

Deleting an Execution Method

Before deleting an Execution Method, ensure all Job and Folders that currently use it have been updated to remove references to it. To view where it is referenced, double-click the Execution Method and select the References tab.

1. Click Execution Methods from the Shortcuts menu.
2. Click an Execution Method.
3. Click X.
4. When you are prompted to confirm the deletion, click Yes.

Execution Method Definition Tabs

Execution Method

This tab contains the basic information about the Execution Method.

• Method Name - This is the unique identifier for the Execution Method.
• Description - This reference property is used to summarize the Execution Method definition.
• Last Changed - This property displays the date and time this Execution Method parameter was last modified.

Parameters

Execution Method Parameters work the same way as Parameters within Job Definitions and apply to all Jobs using this Execution Method. To add a new Parameter, click Add on the Parameters tab to access the Add a Parameter dialog. Each Parameter displays the following:

• Parameter Name – The unique identifier for the Parameter.
• Type – The data type for the Parameter.
• Prompt – The text that is displayed on the Parameters tab when you manually submit a Job.
• Default Value – The value that is displayed on the Parameters tab when you manually submit a Job.

Template

Templates provide an easy way to include standard pre and post processing for your Jobs. When a Job is submitted, JAMS parses a Job source using either the template defined on this tab or the module defined in the Job Module property for the Job’s source code. Use the built-in text editor to edit the template for this Execution Method.

The example below sets up a simple template that maps two network drives, inserts the Job’s source code, and executes a LogJobComplete program:

NET USE E: \\MyServer\EShare NET USE F: \\MyServer\FShare
<<JAMS.Source>>
C:\LogJobComplete.exe <<JAMS.Job.JobName>>

Properties

Job Properties

The Job Properties tab lets you add Properties and default values that will be used by all Job Definitions that use the selected Execution Method. For example, you could add the Agent property to an Execution Method so the Job Definitions will use that Agent. To add a property, click + and select a Property from the list.

References

The References tab lets you view which Jobs are referencing an Execution Method as well as where the Job is located.

Predefined Execution Methods

JAMS ships with dozens of Predefined Execution Methods that can run a variety of Jobs on Windows, Linux, UNIX and and other operating systems detailed below.
