About Deleting WS-Policies
You can delete WS-Policies that reside in the policy repository by removing the file from the policy repository. Integration Server logs information about the deletion.
When you delete a policy, the Integration Server policy manager recognizes the deletion. Designer will no longer include the policy in the list for policies that can be attached to web service descriptors.
If you delete a policy that is currently attached to a web service descriptor, because the policy will be missing, the web service descriptor will no longer behave as expected:
For a provider web service descriptor,
Integration Server will not be able to handle requests for operations contained in the provider web service descriptor and will log a warning message for each provider web service descriptor in the server log.
For a consumer web service descriptor, the execution of the web service connectors will fail stating that the policy is not found.
