7 Configuring and Testing Composed Service-Level Agreements

This chapter describes how to use the SLA Manager in the Platform Test Environment (PTE) to edit a composed service contract in Oracle Communications Services Gatekeeper.

The Platform Test Environment has been enhanced to provide a graphical interface to the SLA editor for creating and managing composed SLAs. When a user modifies a composed SLA using this editor the corresponding XML file is updated immediately.

The editor provides browsers that provide access to information needed to create and manage SLAs, such as the available identifiers, communication service names, and methods.

For information about composed service contracts, see the discussion of the structure of a composed service contract in Accounts and SLAs Guide.

For information about starting and using the SLA Manager in the PTE, see the discussion of configuring and testing service-level agreements in Platform Test Environment Guide.

Starting the Composed SLA Editor

To start the Composed SLA Editor:

1. In the PTE, connect to Services Gatekeeper and start the SLA Manager.

   For instructions on how to do this, see the discussion of configuring and testing service-level agreements in Platform Test Environment Guide.

2. In the SLA Manager, select the Composed Service Contracts tab.

   The Composed SLA Editor appears.

Editing an SLA

You can edit the following values in a new or previously existing contract:

• Composed Service Name and Start/End Dates

• Rates and Quotas

• Communication Services and Methods

For details about what these values represent, see the discussion of defining service provider group and application group SLAs in Accounts and SLAs Guide. The following sections describe only the mechanics of modifying these values in the editor.

Composed Service Name and Start/End Dates

To change the Composed Service Name, start date (From field), or end date (To field):

1. In the composed service editor with the Composed Service Contract tab selected, click the field that you want to modify.

2. Over-write the existing value with the new value.

   If you are editing the Composed Service Name field, make sure to enter a unique name for the composed service.

3. Click OK.

Rates and Quotas

To edit the rate or quota at the bottom of the editor, with the SLA selected:

1. Check the check box for the rate or quota to be enforced by the SLA.

2. Enter the values for the rate or quota to be applied.

3. Click OK.

Communication Services and Methods

This section describes how to add communication services to the composed service and how to specify the methods that the composed service contract applies.

The methods portion is optional. If no methods are specified, the enforcements apply to all of the communication services's methods. If at least one method is specified, only the specified method or methods participate in the composed service.

Adding Communication Services

To add the communication services that define the composed service contract:

1. Select the Composed SLA in the editor.

2. Click the edit icon:

   
   

   The Service Type of Composed Service box appears. Use the upper pane to add communication services.

Upload an Edited Composed SLA

To upload the edited SLA:

   An alert asks whether the composed SLA is geo-redundant or local.

2. Respond to the alert by clicking the Geo-redundant or Local button.

   A local SLA is enforced locally in the network tier cluster into which it is loaded. A geo-redundant SLA is loaded to and enforced across all network tier clusters in a geo-redundant configuration.

   The composed SLA is uploaded.
