Techniques for hybrid computer thread creation and management
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.
1. A method of operating a computer system to support an application, a first application server environment, and a second application server environment, the method comprising:
intercepting, by a request interceptor component executing on the computer system, a work request relating to the application issued to the first application server environment prior to execution of the work request;
responsive to the request interceptor component, creating, using the computer system, a thread adapted for execution in the first application server environment by an executor component;
responsive to the executor component, attaching to the thread, by a thread dispatcher component executing on the computer system, a context to non-disruptively modify the thread into a hybrid thread that is additionally suitable for execution in the second application server environment; and
responsive to the thread dispatcher component, returning the hybrid thread to the first application server environment by a catcher component executing on the computer system.
2. The method of claim 1 , wherein the context comprises transactional control data of one of the application server environments, security control data of one of the application server environments, monitoring control data of one of the application server environments, diagnostic tracing control data of one of the application server environments, and data enabling access to an application programming interface of one of the application server environments;
wherein the hybrid thread is operable to execute in the first application server environment and in the second application server environment without requiring modification of the first and second application server environment;
wherein the hybrid thread comprises first data that is only visible to a server in the first application server environment and second data is only visible to another server in the second application server environment;
wherein the first application server environment and the second application server environment are incompatible in their program execution models; and
wherein only one of the first application server environment and the second application server environment is a procedural program environment.
