Process Parameters

You can define parameters for process operators. The parameters can accept either literal strings or expressions. You can enter a value as a string without delimiting it in any way. Calculated parameters accept values as JavaScript expressions. Use single or double quotation marks to delimit literal strings in JavaScript.

Note: To help you identify CA Process Automation fields that do not accept expressions, their labels appear in italics.

Calculated parameters allow the following:

• Manipulation of module invocation results and other variables.
• Parameterization of operators.
• Definition of wait conditions based on Boolean expressions (preconditions and wait conditions). Wait conditions can be used to delay processing and synchronize the use of resources by different sequences of operators running simultaneously.

You can define parameters using dataset variables. Dataset variables are available to processes in the following contexts:

• In the CA Process Automation orchestrator context, datasets are referred to as named datasets. Named datasets define variables that are accessible to any process on the same orchestrator. A named dataset is accessed by specifying its full path name in an expression. To view or edit a named dataset, you double-click the dataset object in the Library Browser to open the object in the Dataset Designer.
• In the process context, there is the process dataset. The process dataset is available to any operator in a process. The process dataset is accessed by specifying the keyword process in an expression. You can edit variables in a process dataset in the Dataset palette in the Process Designer.
• For each operator in a process, there is an operator dataset. Variables in an operator dataset are available to the operator and to other operators in the same process. An operator dataset is accessed by specifying the operator name in an expression. You can edit variables in an operator dataset in the Dataset palette in the Process Designer.
