Reference Variables in a Rulebase

You can reference several kinds of variables in a rulebase. By referencing variables, the rulebase can adapt to changes on multiple machines. For example, not all machines store log files or temporary files in the same directory. Also, rulebases used on multiple platforms need to accommodate subtle differences in how path names are expressed. You can use variables rather than specifying this information manually.

Supported Types of Variables

The following types of variables are supported in a TIBCO Hawk rulebase:

•	External, such as user-defined variables

•	Internal, such as the name of a test in a rule

•	Data source, such as a microagent method result field (Data source variables can be referenced in actions only)

Referencing these variables outside of a rulebase is not supported. For more information, see TIBCO Hawk WebConsole User’s Guide.
