Policy Attachments and Local Optimization in Composite-to-Composite Invocations in Oracle SOA Suite:

OWSM supports an Oracle SOA Suite local optimization feature for composite-to-composite invocations in which the reference of one composite specifies a web service binding to a second composite. Local optimization enables you to bypass the HTTP stack and SOAP/normalized message conversions during runtime. Local optimization is not used if the composites are in different containers. If a policy is attached to the web service binding, the policy may not be invoked if local optimization is used.

By default, an OWSM security policy includes a local-optimization property that identifies if the policy supports local optimization. You can view the setting for a policy in Oracle Enterprise Manager Fusion Middleware Control.

• Login to EM console.
• In the navigator, expand the WebLogic Domain folder.
• Right-click on the Domain, and select Web Services > Policies.

•  Select a policy and click Export to File.

• Open the file with a text editor and search for local-optimization to identify the value. This property supports the following values:
• on: Local optimization is used in the attached policy, and the policy is not applied at runtime. 
• off: Local optimization is not used in the attached policy, and the policy is applied at runtime. 
• check-identity: If a JAAS subject exists in the current thread, local optimization is used. Otherwise, local optimization is not used.
