System Level Dialogues

The CLAMP Control Loop Runtime Lifecycle Management uses the following system level dialogues. These dialogues enable the CLAMP runtime capabilities described in Section 2 of TOSCA Defined Control Loops: Architecture and Design. Design Time dialogues will be described in future releases of the system.

1 Commissioning Dialogues

Commissioning dialogues are used to commission and decommission Control Loop Type definitions and to set the values of Common Parameters.

Commissioning a Control Loop Type is a three-step process:

1. The Control Loop Type must be created, that is the Control Loop Type definition must be loaded and stored in the database. This step may be carried out over the REST interface or using SDC distribution.

2. The Common Properties of the Control Loop type must be assigned values and those values must be stored in the database. This step is optional only if all mandatory common properties have default values. The Common Property values may be set and amended over and over again in multiple sessions until the Control Loop Type is primed.

3. The Control Loop Type Definition and the Common Property values must be primed, that is sent to the concerned participants. Once a Control Loop Type is primed, its Common Property values can no longer be changed. To change Common Properties on a primed Control Loop Type, all instances of the Control Loop Type must be removed and the Control Loop Type must be de-primed.

1.1 Commissioning a Control Loop Type Definition using the CLAMP GUI

This dialogue corresponds to a “File → Import” menu on the CLAMP GUI. The documentation of future releases of the system will describe how the Design Time functionality interacts with the Runtime commissioning API.

1.2 Commissioning a Control Loop Type Definition using SDC

1.3 Setting Common Properties for a Control Loop Type Definition

This dialogue sets the values of common properties. The values of the common properties may be set, updated, or deleted at will, as this dialogue saves the properties to the database but does not send the definitions or properties to the participants. However, once a Control Loop Type Definition and its properties are primed (See Section 1.4), the properties cannot be changed until the control loop type definition is de-primed (See Section 1.5).

1.4 Priming a Control Loop Type Definition on Participants

The Priming operation sends Control Loop Type definitions and common property values to participants. Once a Control Loop Type definition is primed, its property values can on longer be changed until it is de-primed.

1.5 De-Prime a Control Loop Type Definition on Participants

This dialogue allows a Control Loop Type Definition to be de-primed so that it can be deleted or its common parameter values can be altered.

1.6 Decommissioning a Control Loop Type Definition in CLAMP

1.7 Reading Commissioned Control Loop Type Definitions

2. Instantiation Dialogues

Instantiation dialogues are used to create, set parameters on, instantiate, update, and remove Control Loop instances.

Assume a suitable Control Loop Definition exists in the Commissioned Control Loop Inventory. To get a Control Loop instance running one would, for example, execute dialogues 2.1, 2.3, and 2.4.

2.1 Creating a Control Loop Instance

Note

This dialogue creates the Control Loop Instance in the Instantiated Control Loop Inventory. The instance is sent to the participants using the process described in the dialogue in Section 2.3.

2.2 Updating Instance Specific Parameters on a Control Loop Instance

2.3 Updating a Control Loop Instance with a Configuration on Participants

2.4 Changing the state of a Control Loop Instance on Participants

2.5 De-instantiating a Control Loop Instance from Participants

2.6 Deleting a Control Loop Instance

2.7 Reading Control Loop Instances

1. Monitoring Dialogues

Monitoring dialogues are used to monitor and to read statistics on Control Loop Instances.

3.1 Reporting of Monitoring Information and Statistics by Participants

3.2 Viewing of Monitoring Information

3.2 Viewing of Statistics

3.3 Statistics Housekeeping

4. Supervision Dialogues

Supervision dialogues are used to check the state of Control Loop Instances and Participants.

4.1 Supervise Participants

4.2 Supervise Control Loops
