Specify Resource Availability and Action Settings

The following properties determine which resources the operator runs. They also determine how the operator responds when resources are unavailable. Set the All resources must be available check box to determine how CA Process Automation handles resource availability. Set the Execute Actions option to determine how CA Process Automation behaves with respect to resource availability and predefined actions.

Follow these steps:

1. Open a process.
2. Drag a Manage Resources operator into the process.
3. Double-click the Manage Resources operator to view its properties.
4. Set the All resources must be available check box:

   Checked

   Specifies that all resources that the actions listed in the Action field require must be available before any action is applied. The operator succeeds only if all the resources become available within the Timeout setting constraints.

   Clear

   Allows the operator to complete only those actions for which resources are available. The operator then succeeds if one or more of the listed actions is successfully executed within the Timeout setting constraints.

5. Set the Execute Actions check box:

   Checked

   The operator runs all the actions, if it can.

   Clear

   The operator does not run any actions. If resources are available within the Timeout constraints, the operator runs the Successful exit link without performing any actions.

6. Save the process.

Note: These settings can be used with a resource that is set to enable or disable a whole set of processes. Before they start their tasks, those processes check that there is no lock on the resource by attempting to take a single resource unit from the resource. Depending on the outcome of the test, some other mechanism can lock or unlock the resource, such as:

• Schedule tasks (where enabling or disabling of the processes is based on time constraints)
• Manually started tasks (using a Start Request Form)
• A process that an external monitoring application starts
• A process that monitors some internal or external condition in a loop
