Abstract

A method and system of increasing efficiency within a data processing system having multiple applications executing within the data processing system. Each of the applications requires a specific environment. A collection of parameters which specify an environment is stored within the data processing system in response to an initialization of the environment for utilization by a first application. Next, the minimal requirements of an second application requesting an environment are determined in response to an attempted initialization of the second application. An existing environment is then utilized if the collection of parameters specifying the environment meets the minimal requirements of the second application, wherein data processing efficiency is increased.

Claims

1. A method of increasing efficiency within a data processing system having multiple applications executing within said data processing system, each of said multiple applications requiring a specific object management environment including a least a list of loaded classes and a set of processing flags, said method comprising the data processing system implemented steps of:

storing within said data processing system a collection of parameters specifying an object management environment in response to initialization of said object management environment for utilization by a first application;

determining minimal object management requirements of a second application requesting an object management environment in response to an attempted initialization of said second application; and

utilizing said object management environment specified by said stored collection of parameters if said collection of parameters meets said minimal object management requirements of said second application, wherein data processing efficiency is increased.

2. The method of increasing efficiency within a data processing system according to claim 1, further comprising:

retaining said object manacement environment after said first application no longer requires said object management environment.

3. The method of increasing efficiency within a data processing system according to claim 2, further comprising:

maintaining an object management environment list identifying each object management environment that has been initialized and retained along with a collection of parameters specifying said object management environment, wherein said list may be utilized to determine whether a collection of parameters specifying an object management environment meets said minimal object management requirements of an application.

4. The method of increasing efficiency within a data processing system according to claim 3, further comprising:

marking each object management environment in said object management environment list as in use if an application is utilizing said object management environment; and

preventing utilization of an object management environment by another application if said object management environment is marked as in use.

5. An apparatus for increasing efficiency within a data processing system having multiple applications executing within said data processing system, each of said multiple applications requiring a specific object management environment including at least a list of loaded classes and a set of processing flags, said system comprising:

storage means for storing within said data processing system a collection of parameters specifying an object management environment in response to initialization of said object management environment for utilization by a first application;

means for determining minimal object management requirements of a second application requesting an object management environment in response to an attempted initialization of said second application; and

utilization means, responsive to said means for determining, for utilizing said object management environment specified by said collection of parameters for execution of said second application if said collection of parameters meets said minimal object management requirements of said requesting application.

6. The apparatus of claim 5, further comprising:

retention means for retaining said object management environment after said first application no longer requires said object management environment.

7. The apparatus of claim 6, further comprising:

maintenance means for maintaining an object management environment list identifying each object management environment that has been initialized and retained along with a collection of parameters specifying said object management environment, wherein said list may be utilized to determine whether a collection of parameters specifying an object management environment meets said minimal requirements of an application.

8. The apparatus of claim 7, further comprising:

marking means for marking each object management environment in said object management environment list as in use if an application is utilizing said environment; and

prevention means for preventing utilization of an object management environment by another application if said object management environment is marked as in use.

9. The apparatus of claim 8, wherein said object management environment list is maintained in a memory.

10. The apparatus of claim 8, wherein said object management environment list is maintained on a hard drive unit.

11. A data processing system for managing object management environments within said data processing system, each object management environment including at least a list of loaded classes and a set of processing flags, to increase efficiency of an application requiring a specific object management environment, said data processing system comprising:

determination means for determining whether an application requiring a specific object management environment can utilize a reusable object management environment in response to an attempted initialization of said application;

search means for determining whether a reusable object management environment is available;

comparison means for comparing a reusable object management environment with said required object management environment of said application in response to an availability of a reusable object management environment; and

connection means for connecting said application with said object management environment if said object management environment fulfills at least a minimum set of parameters for said required object management environment of said application.

12. The data processing system of claim 11, wherein said search means includes:

an object management environment list of reusable object management environments, including parameters specifying each reusable object management environment; and

means for comparing parameters of a required object management environment of an application to said parameters within said object management environment list.

14. The data processing system of claim 12 further comprising marking means for marking a reusable object management environment as active in response to a connection of said reusable object management environment with an application.

15. A data processing system for managing object management environments within said data processing system, each object management environment including at least a list of loaded classes and a set of processing flags, to increase efficiency of applications requiring specific object management environments, data processing system comprising:

determination means, responsive to a request for an object management environment for an application, for determining whether an object management environment is available;
