5.2.4 Replacing J2EE applications
You replace J2EE applications in the case of version up and maintenance of running J2EE applications.
When you do not want to stop the services when replacing J2EE applications, you need to execute an appropriate service lock. The CTM will be used to control the request from the client to the J2EE server, and the J2EE application is replaced without stopping the entire system. As a result, the J2EE application is replaced in the online status while accepting the requests from the client. Note that CTM can control only the requests for remote interface invocation of the Stateless Session Bean that uses the RMI-IIOP communication.
The CTM can only be used in the products that contain Cosminexus Component Transaction Monitor in the component software. For available products, see 2.2.1 Relationship of products and component software in the manual uCosminexus Application Server Overview.
