Using a pre-defined system parameter

To use a system parameter:

  1. In the Object Navigator, expand the Data Model node, then expand the System Parameters node.

  2. Double-click the Properties icon (the properties icon) for the desired parameter to display the Property Inspector.

  3. Under the Parameter node, set the Initial Value property, if required.

  4. To validate the parameter's value at runtime, set the Validation Trigger property by clicking the property field to display the PL/SQL Editor and define the PL/SQL to be triggered at runtime.
