Configure the WS-Transaction policy

When you work with policy sets in the administrative console, you can configure the WS-Transaction policy type for the WS-AtomicTransaction (WS-AT) and the WS-BusinessActivity (WS-BA) protocols. We can configure whether a client propagates, and a server receives, a WS-AT context, and whether a client propagates, and a server receives, a WS-BA context.

We must be working with a policy set that includes the WS-Transaction policy type.

Do not edit the policies associated with the provided default policy sets.

To modify the WS-Transaction policy settings, use a copy of a default policy set or create a new policy set. We can configure the policies for the WS-AtomicTransaction and WS-BusinessActivity protocols. The WS-AT protocol supports coordination of activities so that either all the activities occur, or none of them occur. The WS-BA protocol supports coordination of activities that are more loosely coupled than atomic transactions and that therefore require a compensation process if a failure occurs in the business activity.

When you add a WS-Transaction policy, it is equivalent to setting the following deployment descriptors that are associated with an EJB or web module:

• Use Web Services Atomic Transaction

• Send Web Services Atomic Transaction on requests
• Execute using Web Services Atomic Transaction on incoming requests

A WS-BA context is sent if the client is running in a BusinessActivity scope (BAScope). A provider runs in a BAScope if it receives a message that contains a WS-BA context, as long as the provider is set to run EJB methods in a Business Activity scope.

Procedure

1. In the navigation pane of the administrative console, click Services > Policy sets > Application policy sets > policy_set_name > [Policies] WS-Transaction. The WS-Transactions settings pane is displayed.

2. In the WS-AtomicTransaction section, select the option you require:
   • Mandatory. For a client, the client always propagates a WS-AT context on an outbound request. For a server, any request that is received must include a WS-AT context, otherwise the request is rejected.
   • Supports. For a client, the client can propagate a WS-AT context on an outbound request when that context is available. For a server, if a request includes a WS-AT context, the context is imported and established on the thread before the request is processed.
   • Never. For a client, the client never propagates a WS-AT context on an outbound request. For a server, any request that is received must not include a WS-AT context, otherwise the request is rejected.

3. In the WS-BusinessActivity section, select the option you require:
   • Mandatory. For a client, the client always propagates a WS-BA context on an outbound request. For a server, any request that is received must include a WS-BA context, otherwise the request is rejected.
   • Supports. For a client, the client can propagate a WS-BA context on an outbound request when that context is available. For a server, if a request includes a WS-BA context, the context is imported and established on the thread before the request is processed.
   • Never. For a client, the client never propagates a WS-BA context on an outbound request. For a server, any request that is received must not include a WS-BA context, otherwise the request is rejected.

4. Click OK.

5. Save your changes to the master configuration.

Results

After you configure the WS-Transaction policy, the associated policy set uses this policy to support WS-AtomicTransaction and WS-BusinessActivity.
