Managing Web Service Policies 7-27 affects all policy subjects to which the policy is attached. Therefore, before making any changes to your policies, Oracle recommends you do a usage analysis to see which subjects are using a particular policy. To perform a usage analysis: 1. Navigate to the Web Services Policies page as described in Navigating to the Web Services Policies Page in Fusion Middleware Control on page 7-2. The Attachment Count column of the Policies table shows the number of subjects to which a policy is attached. 2. Click the number in the Attachment Count column for the selected policy to display the Usage Analysis page Figure 7–18 . Alternatively, you can select the policy from the Policies table and click View. In the Policy Information region of the page, click the Attachment Count number in the Usage Analysis field to display the Usage Analysis page. Figure 7–18 Usage Analysis for a Policy The Policy Subject List is filtered by subject type. The table displays a list of the policy subjects, of the selected type, to which the policy is attached. Subjects are organized using the following subject types: Repository Document, SOA Component, SOA Reference, SOA Service, WLS Web Service Client, WLS Web Service Endpoint, Asynchronous Callback Client, Web Service Connection, Web Service Client, and Web Service Endpoint. Note that the Policy Subject List summary table displays fields that are relevant to the selected policy subject type only. The total number of policy subjects to which the policy is attached is shown at the bottom of the page in the Attachment Count field. Note: The usage analysis simply identifies which policy subjects will be affected; it does not define the effect of the change. You need to evaluate the change on each of the policy subjects and determine if you should proceed. 7-28 Oracle Fusion Middleware Security and Administrators Guide for Web Services 3. To view the other policy subjects to which the policy is attached, select the subject type from the Subject Type menu. The Subject Type menu provides an attachment count for each subject type to which the policy is attached. Figure 7–19 Subject Type Menu on Usage Analysis Page

4. In cases where multiple domains share the same Oracle WSM Repository to store

Oracle WSM metadata, you can specify whether you want to view policy subjects in the Local Domain or in all domains in the enterprise. To view the policy subjects for all domains in the enterprise, select Enterprise in the View Option field. Figure 7–20 View Option Field on Usage Analysis Page Please note: ■ Both enabled and disabled policy references are included in the policy usage count. For information about disabling a policy reference, see Enabling or Disabling a Policy for a Single Policy Subject on page 7-23 and Enabling or Disabling a Policy for All Subjects on page 7-25. ■ After attaching a policy to an Oracle Infrastructure Web Service endpoint, you need to restart the Web service application to display an accurate policy usage count. You do not need to restart a SOA composite or a WebLogic Java EE Web service application. ■ You must invoke an ADF DC client to display an accurate policy usage count. Policy Advertisement For a standard WSDL ?wsdl, you can publish different version combinations for WS-Policy and WS-SecurityPolicy. For example, http:localhost:8080abc?wsdlwsp=1.5wssp=1.2 returns a WSDL with the following policy versions published: WS-Policy 1.5 and WS-SecurityPolicy 1.2.
