A computer-implemented method of establishing metadata associated with a transaction in a transaction processing system having application logic for executing the transaction, the computer-implemented method includes receiving, from a requestor, request data associated with the transaction, the request data comprising data and metadata. The method also includes peeking, during receiving the request data, of the request data looking for the metadata associated with the transaction and responsive to finding metadata associated with the transaction, directly instantiating an instance of application logic.

Establishing transaction metadata

A technique for operating a computer system to support an application, a first application server environment, and a second application server environment includes intercepting a work request relating to the application issued to the first application server environment prior to execution of the work request. A thread adapted for execution in the first application server environment is created. A context is attached to the thread that non-disruptively modifies the thread into a hybrid thread that is additionally suitable for execution in the second application server environment. The hybrid thread is returned to the first application server environment.

Techniques for hybrid computer thread creation and management

A method, system, and computer program product that includes a processor cataloging a current resource definition and a current transaction state for the resource. The processor recovers the resource and a transaction state for the resource after an emergency restart, by utilizing the current resource definition and the current transaction state, wherein the recovering comprises recovering transactions of the resource. The processor completes or backs out of the transactions. The processor closes the resource and the processor recovers the resource by utilizing a global catalog.

Recovery of local resource

Operating an online transaction processing system to perform an application including a first module call by performing the following steps (not necessarily in the following order): (i) assigning a dedicated search path to the application, where the search path specifies an ordered set of location(s) for searching for module code, the set of location(s) includes at least a first dynamic module library and the first dynamic module library is ahead of any other locations which may be included in the dedicated search path; (ii) running the application through the transaction processing system; (iii) receiving the first module call, from the running of the application, specifying a requested module using a requested module name; and (iv) in response to the module call, locating the requested module based on the requested module name and the dedicated search path.

Application multi-versioning in a traditional language environment

A legacy machine-oriented language interface definition is received of a new module to be implemented, using an object-oriented language, to provide a new feature within a legacy machine-oriented language application that is executable within a legacy application execution platform. An object-oriented class definition and bridging code that interfaces the object-oriented class definition to the legacy machine-oriented language interface definition are generated. An updated version of the object-oriented class definition is received that includes object-oriented code that implements functionality of the new feature within the new module. A new executable version of the legacy machine-oriented language application is built. The new executable version of the legacy machine-oriented language application is executable within the legacy application execution platform, and includes the new module as a new object accessible using the legacy machine-oriented language interface definition with the functionality of the new feature as implemented by the object-oriented code.

Automated generation of bridging code to augment a legacy application using an object-oriented language

According to one exemplary embodiment, a method for dynamically timing out a first process within a plurality of suspended processes is provided. The method may include determining that a second process is attempting to suspend. The method may also include determining if a number of suspended processes plus one is less than a threshold value. The method may then include selecting the first process within the plurality of suspended processes to prematurely time out based on determining that the number of suspended processes plus one is not less than the threshold value. The method may further include timing out the selected first process. The method may also include suspending the second process.

Dynamic timeout period adjustment of service requests

A method, executed by a computer, includes receiving a request to instantiate an instance of a thread-local manager for a particular thread, instantiating the instance of the thread-local manager, and providing global visibility to the instance of the thread-local manager. The method further includes manipulating thread-local variables corresponding to the particular thread and removing all the thread-local variables when the particular thread completes a task. A computer system and computer program product corresponding to the above method are also disclosed herein.

Enhanced management of thread-local objects

As disclosed herein a method, executed by a computer, includes receiving a request to instantiate an instance of a thread-local manager for a particular thread, instantiating the instance of the thread-local manager, and providing global visibility to the instance of the thread-local manager. The method further includes manipulating thread-local variables corresponding to the particular thread and removing all the thread-local variables when the particular thread completes a task. A computer system and computer program product corresponding to the above method are also disclosed herein.
