About Subscriptions

Policy Manager provides UDDI 3.0-compliant Subscription functionality that allows clients with third-party registries (subscribers) to monitor a subset of data within the Policy Manager Registry. Subscriptions can be used to obtain updates regarding any type of business entity or business service change that would be of interest to your organization.

The relationship between a subscriber and the Policy Manager Registry is established through the following steps:

  1. In the Configure > Registry > Subscriptions section of the Policy Manager Management Console, define a subscription request.
  2. Configure one-way replication between the third-party registry (slave registry) and Policy Manager registry (master registry).

To view the Subscriptions Summary page, go to Configure > Registry and then click the Subscriptions tab.
