Creating a Policy Type object
Active Roles stores Policy Type objects in the Policy Types container. You can access that container in the Active Roles Console by expanding the Configuration > Server Configuration branch of the Console tree.
To create a new Policy Type object
-
In the Console tree, under Configuration > Server Configuration > Policy Types, right-click the Policy Type container in which you want to create a new object, and select New > Policy Type.
For example, if you want to create a new object in the root container, right-click Policy Types.
-
In the New Object - Policy Type wizard, type a name, a display name and, optionally, a description for the new object.
The display name identifies the activity type in the Workflow Designer. The description text is used as a default description for every activity that is based on this Policy Type object.
-
Click Next.
-
Click Browse and select the Script Module containing the script that will be used by the workflow activities of this type.
The Script Module must exist under the Configuration > Script Modules container.
-
In the Policy Type category area, select the Workflow activity option.
-
From the Function to run list, select the name of the script function that will be run by the workflow activities of this type.
The list contains the names of all the functions found in the script you selected in Step 4. Every activity of this type will run the function you select from the Function to run list.
-
From the Use in list, select the appropriate option to indicate the category of the workflow in which the activity of this type can be used:
-
Change workflow: The activity can be used only in change workflows, that is, workflows intended to run upon operation requests that meet certain conditions.
-
Automation workflow: The activity can be used only in automation workflows, that is, workflows intended to run on a scheduled basis or on user demand.
-
Any workflow: The activity can be used in both change and automation workflows.
-
From the Function to declare parameters list, select the name of the script function that defines the parameters specific to this type of workflow activity.
The list contains the names of all the functions found in the script you selected in Step 4. Every activity of this type will have the parameters that are specified by the function you select from the Function to declare parameters list. Normally, this is a function named onInit.
-
Click Policy Type Icon to verify the image that denotes this type of activity. To choose a different image, click Change and open an icon file containing the image you want.
This image appears next to the display name of the activity type in the Workflow Designer, to help identify and visually distinguish this activity type from the other activity types.
The image is stored in the Policy Type object. In the dialog box that appears when you click Policy Type Icon, you can view the image that is currently used. To revert to the default image, click Use Default Icon. If the button is unavailable, then the default image is currently used.
-
Click Next and follow the steps in the wizard to complete the creation of the new Policy Type object.
Changing an existing Policy Type object
You can change an existing Policy Type object by changing the general properties, script, or icon. The general properties include the name, display name, and description. The Policy Type objects are located under Configuration > Server Configuration > Policy Types in the Active Roles Console.
The following table summarizes the changes you can make to an existing Policy Type object, assuming that you have found the object in the Active Roles Console.
Table 50: Policy Type object changes
Name of the object |
Right-click the object and click Rename. |
The name is used to identify the object, and must be unique among the objects held in the same Policy Type container. |
Display name or description |
Right-click the object, click Properties and make the necessary changes on the General tab. |
Changing the display name also changes the name of the activity type in the Workflow Designer. You may need to refresh the view in the Workflow Designer for the new name to be displayed. |
Script Module |
Right-click the object, click Properties, navigate to the Script tab, click Browse, and then select the Script Module you want. |
You can change the script in the Script Module that is currently associated with the Policy Type object instead of selecting a different Script Module. To view or change the script, find and select the Script Module in the Active Roles Console tree, under Configuration > Script Modules.
Changing the script affects all the existing workflow activities of this type. If you add an activity to a workflow and then change the script for the Policy Type object based on which the activity was created, the activity will run the changed script. |
Function to run |
Right-click the object, click Properties, navigate to the Script tab, and then choose the appropriate function from the Function to run list. |
Changing this setting causes the activities of this type to run function you have selected.
Changing the function does not affect the existing activities of this type. If you add a new activity of this type, the activity will run the new function. |
Workflow category |
Right-click the object, click Properties, navigate to the Script tab, and then choose the appropriate option from the Use in list. |
This setting determines the workflow category (change workflow, automation workflow, or any workflow) in which the activity of this type is allowed. After you have changed this setting, an activity of this type can only be added to the corresponding workflow category. Thus, if you select the Change workflow option, the activity of this type cannot be added to an automation workflow. |
Function to declare parameters |
Right-click the object, click Properties, navigate to the Script tab, and then choose the appropriate function from the Function to declare parameters list. |
Changing this setting changes the list of the activity parameters specific to this activity type. The changes do not affect the parameters of the existing activities of this type. When you add a new activity of this type, the list of the activity parameters is built using the new function to declare parameters. |
Policy Type icon |
Right-click the object, click Properties, navigate to the Script tab, click Policy Type Icon, and then do one of the following:
|
Changing this setting changes the image that appears next to the display name of the activity type in the Workflow Designer, on the pane located next to the workflow process diagram. |
Using Policy Type containers
You can use a Policy Type container to store related Policy Type objects and other Policy Type containers.
Containers provide a means for additional categorization of custom activity types, making it easier to locate and select an activity type in the Workflow Designer. The activities toolbox next to the workflow process diagram lists the custom activity types along with the containers that hold the respective Policy Type objects. To prevent containers from cluttering the activities toolbox, the Workflow Designer displays only the containers that are direct descendants of the Policy Types container, and disregards the lower-level containers. To clarify this behavior, let us consider a path to a Policy Type object such as Policy Types/Container A/Container B/Object C. In this case, the Workflow Designer only displays Container A and the activity type C under Container A, disregarding Container B.
To create a new Policy Type container
-
In the Console tree, under Configuration > Server Configuration > Policy Types, right-click the Policy Type container in which you want to create a new container, and select New > Policy Type Container.
For example, if you want to create a new container in the root container, right-click Policy Types.
-
In the New Object - Policy Type Container Wizard, type a name and, optionally, a description for the new container.
The name of the container will be displayed in the Workflow Designer if the container is located directly in the Policy Types container.
-
Click Next and follow the steps in the wizard to complete the creation of the new container.
Exporting activity types
You can export Policy Type objects so that the definition of the activity types is stored in an XML file which can be imported in a different Active Roles environment. Exporting and then importing Policy Type objects make it easy to distribute custom activity types to other environments.
To export a Policy Type object or container
You can select multiple Policy Objects to export, or you can select a container to export all Policy Type objects and containers held in that container. In either case, the Export operation creates a single XML file that can later be imported to any container under the Policy Types node.
Export of Policy Type objects creates an XML file representing both the objects and the Script Modules containing the scripts for each activity type being exported. During an import, Active Roles creates the Policy Type objects and the Script Modules based on the data found in the XML file. As a result of the import, the activity types are replicated to the new environment and can be used the same way as in the environment from which they were exported.
