View detail of a service client and managing policy sets using the dmgr console

Use this dmgr console task to view the detail of your service client reference and to manage the policy sets for the service, its endpoints and operations.
Before completing this task, you need to install one or more Java API for XML-based Web Services (JAX-WS) web services, and attach a policy set to each web service. You have developed a web service containing all the necessary artifacts and deployed the web services application into the application server instance. Now, we can attach or detach policy sets and manage the associated bindings.
The policy set information is displayed in the Attached Policy Set column. If a policy set is directly attached, then the policy set name appears; for example, WS-I RSP is displayed. If there is no policy set attached, and a policy set is attached at a higher level, then the word inherited in parentheses is appended to the policy set name, as the following example demonstrates: WS-I RSP (inherited). If there is no policy set attached directly or at a higher level, then None is displayed.
Every attachment of a policy set to a service artifact has an assigned binding. The binding information is displayed in the Binding column. The Binding column can contain the following values:

Not applicable. There is no policy set attached, either directly or to a higher level service resource.
Binding_name or Default. The binding name is displayed if a policy set is attached directly and an application-specific binding or a general binding is assigned, for example, MyBindings1. Default is displayed if a policy set is attached directly but the service resource uses the default bindings.
Binding_name (inherited) or Default (inherited). A service resource inherits the bindings from an attachment to a higher level resource.

In v7.0 and later, there are two types of bindings, application specific bindings and general bindings.
Application specific binding
We can create application specific bindings only at a policy set attachment point. These bindings are specific to and constrained to the characteristics of the defined policy. Application specific bindings are capable of providing configuration for advanced policy requirements, such as multiple signatures; however, these bindings are only reusable within an application. Furthermore, application specific bindings have very limited reuse across policy sets.
When creating an application specific binding for a policy set attachment, the binding begins in a completely unconfigured state. You must add each policy, such as WS-Security or HTTP transport, to override the default binding and fully configure the bindings for each policy that we have added. For WS-Security policy, some high level configuration attributes such as TokenConsumer, TokenGenerator, SigningInfo, or EncryptionInfo might be obtained from the default bindings if they are not configured in the application specific bindings.
For service clients, we can only create application specific bindings by selecting Assign Binding > New Application Specific Binding for service client resources that have an attached policy set. See service clients policy sets and bindings collection. Similarly, for service clients, we can only create application specific bindings by selecting Assign Binding > New Application Specific Binding for service client resources that have an attached policy set. See service client policy set and bindings collection.
General bindings
General bindings were introduced in v7.0. These bindings can be configured to be used across a range of policy sets and can be reused across applications and for trust service attachments. Though general bindings are highly reusable, they are however not able to provide configuration for advanced policy requirements, such as multiple signatures. There are two types of general bindings:

General provider policy set bindings
General client policy set bindings

We can create general client policy set bindings by accessing Services > Policy sets > General provider policy set bindings > New in the general provider policy sets panel or by accessing Services > Policy sets > General client policy set bindings > New in the general client policy set and bindings panel. See defining and managing service client or provider bindings.
Depending on your assigned security role when security is enabled, you might not have access to text entry fields or buttons to create or edit configuration data. Review the administrative roles documentation to learn more about the valid roles for the application server.

Open the dmgr console.
In the navigation pane, click Applications > Application Types > WebSphere enterprise applications >Service_client_application_instance > Service clients.
Select one or more service, endpoints and operations of interest and view the associated service, endpoints and operations.
We can perform any of the following actions:

Click Attach, to attach a policy set to a selected service, endpoint or operation.

Click, Detach, to detach a policy set from a list of attached policy sets for a service, endpoint or operation. The service name is the service client reference in the application.

Click Assign Binding to select from a list of available bindings for the selected policy set attachment. All the bindings are listed along with the following options:

Binding descriptions. Use the descriptions of the default bindings for the selected policy set attachment.

Bindings Description
Default Default binding for the selected service client, endpoint, or operation. We can specify client and provider default bindings to be used at the cell level or global security domain level, for a particular server, or for a security domain. The default bindings are used when an application-specific binding has not been assigned to the attachment. When you attach a policy set to a service resource, the binding is initially set to the default. If we do not specifically assign a binding to the attachment point using this Assign Binding action, the default specified at the nearest scope is used.
For any policy set attachment, the run time checks to see if the attachment includes a binding. If so, it uses that binding. If not, the run time checks in the following order and uses the first available default binding:

Default general bindings for the server
Default general bindings for the domain in which the server resides
Default general bindings for the global security domain

New Application Specific Binding Select this option to create a new application-specific binding for the policy set attachments. The new binding you create is used for the selected resources. If we select more than one resource, ensure that all selected resources have the same policy set attached.
Client sample Select this option to use the Client sample binding.
Client sample V2 Select this option to use the Client sample V2 binding when we are using either the Kerberos V5 WSSecurity default or the TrustServiceKerberosDefault policy sets.
Saml Bearer Client sample Select this option to use the Saml Bearer Client sample. The Saml Bearer Client sample extends the Client sample binding to support SAML Bearer token usage scenarios. We can use this sample with any of the SAML bearer token default policy sets.
Saml HoK Symmetric Client sample Select this option to use the Saml HoK Symmetric Client sample. The Saml HoK Symmetric Client sample extends the Client sample binding to support SAML holder-of-key (HoK) symmetric key token usage scenarios. We can use this sample with one of the SAML HoK Symmetric key default policy sets: either SAML11 HoK Symmetric WSSecurity default or SAML20 HoK Symmetric WSSecurity default.

To close the drop down list for the assign binding action, click Assign Binding.

Results

When you finish this task, a policy set is attached, detached or a binding is assigned to the service artifact.

Example

You have configured a service client reference, EchoService12 in the application instance, WSSampleClientSei. Now to attach the WSSecurity default policy to the EchoService12Port endpoint of the EchoService12 service client reference. First locate EchoService12 in the Services > Service clients collection. Click the EchoService12 service client reference. Select the check box for the EchoService12Port resource and click Attach. Select the WSSecurity default policy from the list. Click Save, to save your changes to the master configuration.

We can now proceed to manage policy sets and bindings for service clients at the application level using the dmgr console.

Subtopics

Service client settings
Use this dmgr console page to manage the settings for the service clients. We can attach and detach policy sets to a service, its endpoints, or operations. We can select default bindings, create new application-specific bindings, or use existing bindings for an attached policy set. We can view or change whether the client uses the policy of the service provider.
