Abstract: This disclosure provides various embodiments for providing transparently stateful execution of stateless applications. A request associated with an application is received and includes at least one operation to be executed by the application as well as a set of first state information. The application determines if the operations are to be executed statelessly or not. If the application is to be executed statelessly, the first state information is retrieved from the request and used to initialize the application. If not, then the first state of the application is retrieved from a location other than the received request. The operations are then executed by the application in the application's appropriate first state. A response including the relevant information associated with the response as well as an updated set of state information identifying the application's second state is generated and transmitted to the client.

Abstract: Deleting a data record from the second level storage or main store is disclosed. A look-up is performed for the data record in the first level storage, where the data record is defined by a row identifier. If the row identifier is found in the first level storage, a look-up is performed for an updated row identifier representing an update of the data record in the second level storage and the main store, the update of the data record being defined by an updated row identifier. If the updated row identifier is found in the second level storage, an undo log is generated from the first level storage to invalidate a row identifier of the row identifier. A flag is generated representing an invalid updated row identifier, and a redo log is generated to restore the data record in the first level storage.

Abstract: The present disclosure describes methods, systems, and computer program products for providing a remote device remote access to software functions.

Abstract: A customer's Version Control System (VCS) is set up to store files associated with an application having application versions. The customer's VCS includes a set of branches defined correspondingly to a set of systems of a customer change management landscape. A first branch comprises files of a first version of the application. A second version of the application is populated into the first branch. Existing customizations, modifications, and created runtime authoring objects during design time and runtime of the first version of the application are applied over the second version. The changes are submitted into the customer's VCS and an updated version is generated in the first branch. The updated version is transported to a second branch through merging the first branch and the second branch. When a request for deployment is received, a reference to the second branch pointing to the updated version of the application is provided.

Abstract: This disclosure provides various embodiments of software, systems, and techniques for controlled interruption of batch job processing. In one instance, a tangible computer readable medium stores instructions for managing batch jobs, where the instructions are operable when executed by a processor to identify an interruption event associated with a batch job queue.

The instructions then restart the interrupted batch job at the restart point.

Abstract: In a computing system having a multiple central processing unit (CPU) cores the task scheduler can be configured to generate one or more priority value lists of elements, with each priority value list comprising elements having the same priority value. The priority queue of a task scheduler can be populated by links to priority value lists that are arranged in order of priority. Worker threads can access an input SIAO and determine the maximum priority of any element in the input SIAO. If the input SIAO has an element with higher priority than the priority queue of the task scheduler then the worker thread can cause the task associated with that element to be processed, otherwise the worker thread can cause all of the elements of the SIAO to be put into the priority value lists linked to by the elements in the priority queue.
