Abstract

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.

First claim

What is claimed is:

1. A computer system comprising:
a memory storing instructions and a processor configured to execute the instructions to perform a method comprising:
intercepting a work request relating to an application issued to a first application server environment prior to execution of the work request;
creating a thread adapted for execution in the first application server environment;
attaching a context to the thread that non-disruptively modifies the thread to create a hybrid thread that is additionally suitable for execution in a second application server environment without requiring modification of the first and second application server environments, wherein the hybrid thread comprises first data that is only visible to a server in the first application server environment and second data that 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
returning the hybrid thread to the first application server environment.

2. The computer system of claim 1 , wherein the first application server environment is a procedural program environment, and wherein the second application program environment is an object-oriented program environment.

3. The computer system of claim 1 , wherein only one of the first application server environment or the second application server environment is a procedural program environment.

4. The computer system of claim 1 , wherein only one of the first application server environment or the second application server environment is an object-oriented program environment.

5. The computer system of claim 1 , wherein the context comprises transactional control data of one of the application server environments.

6. The computer system of claim 1 , wherein the context comprises security control data of one of the application server environments.

7. The computer system of claim 1 , wherein the context comprises monitoring control data of one of the application server environments.

8. The computer system of claim 1 , wherein the context comprises diagnostic tracing control data of one of the application server environments.

9. The computer system of claim 1 , wherein the context comprises data enabling access to an application programming interface of one of the application server environments.

10. A method comprising:
intercepting a work request relating to an application issued to a first application server environment prior to execution of the work request;
creating a thread adapted for execution in the first application server environment;
attaching a context to the thread that non-disruptively modifies the thread to create a hybrid thread that is additionally suitable for execution in a second application server environment without requiring modification of the first and second application server environments, wherein the hybrid thread comprises first data that is only visible to a server in the first application server environment and second data that 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
returning the hybrid thread to the first application server environment.

11. The method of claim 10 , wherein the context comprises transactional control data of one of the application server environments and security control data of one of the application server environments.

12. The method of claim 10 , wherein the context comprises 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.

13. The method of claim 10 , wherein the context comprises transactional control data of one of the application server environments, monitoring control data of one of the application server environments, and diagnostic tracing control data of one of the application server environments.

14. The method of claim 10 , wherein the context comprises transactional control data of one of the application server environments, security control data of one of the application server environments, and diagnostic tracing control data of one of the application server environments.

15. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:
intercepting a work request relating to an application issued to a first application server environment prior to execution of the work request;
creating a thread adapted for execution in the first application server environment;
attaching a context to the thread that non-disruptively modifies the thread to create a hybrid thread that is additionally suitable for execution in a second application server environment without requiring modification of the first and second application server environments, wherein the hybrid thread comprises first data that is only visible to a server in the first application server environment and second data that 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
returning the hybrid thread to the first application server environment.

16. The computer program product of claim 15 , wherein the first application server environment comprises a customer information control system (CICS) procedural programming environment, wherein the second application server environment comprises a Java object-oriented programming environment, and wherein attaching a context to the thread comprises implementing a Java ThreadExecutor.

17. The method of claim 10 , wherein the first application server environment is a procedural program environment, and wherein the second application program environment is an object-oriented program environment.

18. The method of claim 10 , wherein only one of the first application server environment or the second application server environment is a procedural program environment.

19. The method of claim 10 , wherein only one of the first application server environment or the second application server environment is an object-oriented program environment.

20. The method of claim 10 , wherein the context is selected from a group consisting of:
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.
