Abstract: A system and method for patching cloud services for use with a cloud computing environment. In accordance with an embodiment, a cloud environment includes a cloud services infrastructure, which allows a suite of software applications, middleware, and database offerings to be delivered to customers in a self-service, elastically scalable manner. Over time, it may become necessary to update one or more of the deployed services. In accordance with an embodiment, services can be patched using a two phase approach. During an offline phase, patches are used to update shared components, such as middleware volumes, without disrupting any currently running services. Subsequently, during an online phase, patched components are enabled on all service hosts, and any necessary domain update/upgrade operations are invoked.

Abstract: A system and method for providing a publish and subscribe server that includes channels to allow web based clients to send and receive asynchronous messages. In accordance with an embodiment, the system provides a Hypertext Transfer Protocol (HTTP) publish and subscribe (pub/sub) server that includes a channels-based means to allow web based clients to send and receive asynchronous messages over HTTP, including in some embodiments messages published by a JMS provider.

Abstract: A model for extending application server functionality includes two types of libraries: an automatically-referenced (auto-ref) library and a superseding library. The auto-ref library includes a special tag that identifies it as the auto-ref library and a pattern that restricts the application types that can refer to it. Once the auto-ref library is deployed, it is automatically referred to by all applications as long as they are not excluded by the restricting pattern. The code contained in the auto-ref library is merged into the application code and the configuration of the library is merged into the application configuration at deployment time. The superseding library also includes an identifying tag and a restriction pattern. At deployment, however, the code and configuration data in the superseding library overrides the corresponding application configuration and code. The remaining code of the application that is not overridden by the superseding library is used without any modification.

Abstract: A system and method for patching Java cloud services for use with a cloud computing environment. In accordance with an embodiment, a cloud environment, such as Oracle Public Cloud (OPC), includes a Java cloud services (JCS) infrastructure, which allows a suite of software applications, middleware, and database offerings to be delivered to customers in a self-service, elastically scalable manner. Over time, it may become necessary to update one or more of the deployed services. In accordance with an embodiment, services can be patched using a two phase approach. During an offline phase, patches are used to update shared components, such as middleware volumes, without disrupting any currently running Java services. Subsequently, during an online phase, patched components are enabled on all Java service hosts, and any necessary domain update/upgrade operations are invoked.

Abstract: In accordance with embodiments, there are provided mechanisms and methods for sharing sessions between web-based applications. These mechanisms and methods can enable embodiments to provide sharing sessions between web-based applications. A method embodiment includes receiving a request to access a second web application from a user currently accessing a first web application. Session information from a first session between the user and the first web application is provided to a second session established between the user and the second web application. Access to the second web application is provided responsive to the user's request, using session information from the first session.
