The Web service uses a stateless session bean and enables a single command to be run and the output returned in a single request. The method RmmJApi.runCommandXml enables a command to be run by a single method call. See Table 1 for additional information.

Each caller of the Web service can use a different bean in WebSphere®, and this enables multiple commands to be run in sequence and also in parallel. By customizing implementation options, you can enable WebSphere to instantiate a stateless session bean to support the DFSMSrmm Web service and to retain the session bean for use by any Web service requests. You can also limit how many instances of the bean can be running at one time.
