Abstract: The present disclosure relates to a telecommunication method for controlling data access to a telecommunication server, the telecommunication server being connected to at least one first client terminal via at least a digital cellular telecommunication network, wherein the telecommunication server and the first client terminal communicate via a stateless protocol within at least a first communication session, the first client terminal being a battery powered device, the telecommunication server comprising an electronic document, the electronic document having a plurality of input fields for entry of electronic data, wherein a first lock and a session ID are assigned to the electronic document, the session ID being indicative of the first communication session, wherein the first lock is released by the telecommunication server upon ending the first communication session, the telecommunication server comprising multiple applications for accessing the electronic document, the telecommunication server further com

Abstract: In an example embodiment, a request for an enqueue lock for a first piece of data is received from a client application. At an enqueue server separate from an application server instance, a light-weight enqueue session is then created, including generating a light-weight enqueue session identification for the light-weight enqueue session. An enqueue lock for the first piece of data is stored in the light-weight enqueue session. The light-weight enqueue session identification is then sent to the client application. In response to a detection that a session between the client application and the application server instance has been terminated, all enqueue locks in the light-weight enqueue session are deleted and the light-weight enqueue session is deleted.

Abstract: Methods and systems of monitoring events occurring in a computer system are provided. An event monitoring instruction including a condition is parsed, the event monitoring instruction expressed using syntax defined in source code, the parsing resulting in an event channel to monitor and the condition. Then execution of an application is paused. The event channel is monitored until an event occurs on the event channel. Then an event handler for the event is run in response to the event occurring on the event channel. The condition is evaluated to determine whether the condition is satisfied. Execution of the application is resumed in response to the condition being satisfied.

Abstract: A kernel provides a mechanism allowing various applications (e.g. CRM, logistics, procurement, etc.) hosted on a plurality of different application servers, to share access to a common underlying system (e.g. database). An automated process for implementing a kernel change (e.g. for upgrade or replacement) may employ a “Stop-the-World” approach involving suspension of application server instances, coordinated by the start service of the last application server whose kernel is to be changed. As used herein, suspending refers to halting any processing prior to calling a central service (CS) as long as a CS instance is unavailable, and then to resuming processing once the CS instance becomes available. This suspension of relevant clients avoids errors from arising during the downtime of the CS instance. Once the application server instances are in a stopped state, the CS instance is restarted. Then, the application server instances are resumed, and their kernels are changed.

Abstract: A system, a method and a computer-program product for exchanging communications between user sessions are provided. A first push channel and a first messaging channel on a first application server for connecting a first client to the first application server are established. The first messaging channel communicates with the first push channel, where both channels form a first session corresponding to the first client. A second push channel and a second messaging channel on a second application server for connecting a second client to the second application server are established. The second messaging channel communicates with the second push channel, where both channels form a second session corresponding to the second client. The first and second application servers communicate on a communication network. Messages are exchanged between the first and second messaging channels to form a connection between the first and second clients.

Abstract: Methods and apparatus, including computer systems and program products, for sharing objects in runtime systems and for providing isolation between user sessions in a scalable manner. A user context corresponding to a user session is stored in a shared memory area. Upon receiving a request corresponding to the user session, a process is selected from a set of operating system processes, and a runtime system is selected from a set of runtime systems. The runtime system is bound to the process, and the user context is associated with the runtime system to process the request. In some implementations, sharing user contexts enables virtual machines to be used in a shared but isolated manner: Each user context can be exclusively associated with an available virtual machine from a fixed set of virtual machines, and each virtual machine can be exclusively executed in an available process from a fixed set of processes.

Abstract: Method, apparatus and system for data sharing in runtime systems are described. A set of data objects is identified, where each data object in the set of data objects comprises a reference to runtime metadata about the data object in a first runtime system. For each data object in the set of data objects, the reference to the runtime metadata in the data object is replaced with a proxy. The set of data objects is transmitted to a second runtime system. The transmitting of the set of data objects includes replacing the proxy with the reference to the runtime metadata for each of the set of data objects transmitted to the second runtime system. Further, a shared memory is associated with the first runtime system and the second runtime system such that the first and second runtime systems share us information at the shared memory.

Abstract: Methods and apparatus, including computer systems and program products, for sharing data objects in runtime systems. An identification of a first data object in a first runtime system is received. The first data object references zero or more referenced data objects. A shared closure of data objects, which consists of the first data object and a transitive closure of the referenced data objects, is identified, and a determination is made as to whether the shared closure of data objects is usable in a second runtime system. In some implementations, determining whether a shared closure is usable in a second runtime system includes determining whether each data object in the shared closure is serializable without execution of custom code, or determining whether the runtime class of each object instance in the shared closure is shareable. Using shared closures to share objects between runtime systems can provide isolation between user sessions.

A set of objects is identified, each object having a reference to runtime metadata about the object in a first runtime system. The reference to the runtime metadata in each object is replaced with a proxy, and the set of objects is transmitted to a second runtime system, where the proxy in each object is replaced with a reference to runtime metadata about the object in the second runtime system. In some implementations, the runtime metadata can be installed in the second runtime system if it is not already available. The set of objects can include a shared closure of objects, which can be shared between runtime systems (including virtual machines) located on distinct physical machines. Sharing objects between runtime systems on multiple machines can provide isolation between user sessions in a scalable manner.
