Applying policies using Business Space

You can use Business Space for Mediation Policy administration using either Module mediation policies or Target Service mediation policies.

Module mediation policy administration

In the "Lookup from different tables in database" scenario, described in Mediation policy usage scenarios, policies must be attached to the module containing the Policy Resolution mediation primitive. This section describes how you can complete that task using Business Space widgets.

Complete the following steps before you attach policies to a module:

1. Set up a WSRR definition in the IBM BPM administrative console.

2. From IBM Integration Designer export a mediation module containing a Policy Resolution mediation primitive and primitives with promoted properties as a .ear file.
3. Deploy the .ear file to IBM BPM.
4. Load the .ear file into WSRR as an SCA module.

Procedure

After you complete these steps policies can be attached to the module:

1. Log in to Business Space by navigating to http://WESBHOST:WESBPORT/BusinessSpace.

2. Go to the Solution Administration space.

   Figure 1. Selecting the Solution Administration space

3. Select the Module Administration tab.

   Figure 2. The Module Administration tab

   The Module Browser shows all SCA modules currently deployed to IBM BPM.

4. Expand the module to which you want to apply policies. In this example, it is the VacationFlow module.

5. Select Module Policies.

   Figure 3. Finding the policies associated with your module.

6. Select the required WSRR instance, if necessary.

7. Specify the name of the new policy attachment and click Create.

8. In the Group Name list, select the property group associated with the promoted property that you are setting.

9. Create a new policy by specifying a name and click Next.

   Figure 4. Creating a new policy name.

10. In the Assertions panel, shown in Figure 5, set the value that this policy will apply to the selected Property Name.

11. On the same panel, click Add Assertion.

12. In the Gate Conditions section of the panel, set the name of the gate condition and enter the condition string in the Value field

13. Click Add Gate Condition.

14. Click Save.

    The new Policy Attachment is now listed in the table on the Module Administration page.

Target Service mediation policy administration

In the "Log a message depending on the target service" scenario, described in Mediation policy usage scenarios, policies must be attached to a target service. This section describes how you can complete that task using Business Space widgets.

Complete the following steps before you attach policies to a module:

1. Set up a WSRR definition in the IBM BPM administrative console.

2. From IBM Integration Designer export a mediation module containing a Policy Resolution mediation primitive and primitives with promoted properties as a .ear file.
3. Deploy the .ear file to IBM BPM.
4. Load the .ear file into WSRR as an SCA module.

Procedure

After you complete these steps policies can be attached to the module:

1. Log in to Business Space by navigating to http://WESBHOST:WESBPORT/BusinessSpace.

2. Go to the Service Administration space.

   Figure 7. Selecting the Service Administration space

3. Select the Service Administration tab. The Service Browser page shows all of the services loaded into the specified WSRR instance.
4. Ensure that the correct WSRR instance is selected in the WSRR definition used field.

   Figure 8. The Service Administration tab

5. Expand the target service to which you want to apply policies

6. In the Mediation Policies section of the target service select the Service, Endpoint or Operation to which to apply the policy.

7. Specify the name of the new policy attachment and click Create.

   Figure 9. Finding the policies associated with your module and creating a policy attachment.

8. In the Group Name list select the property group associated with the promoted property that you want to set.

9. Add a new policy name and click Next .

10. In the Assertions section select the property name and provide a value. .

11. Click Add Assertion.

12. If required, create a gate condition, as described in the Module mediation policy administration section.

13. Click Save.
