Abstract

According to one embodiment of the present invention, a system, method and computer program product or the administration of client side property settings in a distributed and heterogeneous environment is provided. According to one embodiment of the present invention, a method comprises establishing communication between a plurality of property agents and a property service, and looking up an identifier in a property repository for each property agent. A property setting in an updated client application associated with a selected one of the property agents is then modified by a database administrator. Changed property settings from the selected one of the property agents are then sent to the property service. Property settings associated with the updated client application are updated in the property repository. The updated property settings are sent from the property service to a plurality of property agents. The property agents may then merge the updated property settings into an associated application.

Claims

1. A method comprising:

establishing communication between a plurality of property agents and a property service;

looking up an identifier in a property repository for each property agent, wherein said identifier is a namespace;

modifying a property setting in an updated client application associated with a selected one of said property agents;

sending changed property settings from said selected one of said property agents to said property service;

updating property settings associated with said updated client application in said property repository;

sending said updated property settings from said property service to a plurality of property agents, wherein sending said property settings from said property service comprises sending a push-down event with said updated property settings to selected ones of said property agents that listen to said namespace; and

using said property agents to merge said updated property settings into an associated application.

2. A method according to claim 1 wherein said client applications use said updated property settings to connect to a respective database server.

3. A method according to claim 2 wherein said sending changed property settings from said selected one of said property agents comprises sending changed property settings under a logical name as a pull-up request to said property service.

4. A method according to claim 3 further comprising looking up said namespace in said property repository based on said logical name.

5. A method according to claim 4 wherein said updating comprises updating property settings in said namespace of said property repository.

6. A method according to claim 1 wherein said updating is performed by a database administrator.

7. A method comprising:

establishing communication between a plurality of property agents and a property service, each property agent being associated with an application, said communication being established under a logical name associated with said property agent;

looking up a namespace in a property repository for each property agent based on said logical name;

modifying a property setting in an updated client application associated with a selected one of said property agents, said modifying being performed by a database administrator;

sending changed property settings from said selected one of said property agents to said property service;

updating property settings associated with said updated client application in said property repository;

sending said updated property settings to a plurality of property agents, wherein sending said sending property settings from said property service comprises sending a push-down event with said updated property settings to selected ones of said property agents that listen to said namespace;

using said property agents to merge said updated property settings into an associated application; and

using said updated property settings to connect said application to a respective database server.

8. A method according to claim 7 said sending changed property settings from said selected one of said property agents comprises sending changed property settings under a logical name as a pull-up request to said property service.

9. A system comprising:

one or more processors;

a plurality of client applications executing in said one or more processors;

a property repository storing property settings for a plurality of said client applications;

a property service for transferring property settings between said client applications and said property repository; and

a plurality of property agents, each associated with one of said client applications, for sending pull-up requests to said property service to update said property repository, wherein said property service sends push-down events with updated property settings to selected ones of said property agents, wherein sending said updated property settings from said property service comprises sending a push-down event with said updated property settings to selected ones of said property agents that listen to a namespace.

10. A system according to claim 9 wherein said client applications are a set of distributed heterogeneous client applications.

11. A system according to claim 10 wherein said client applications include a database driver and an application server.

13. A system according to claim 10 wherein said property settings in said property repository are organized under different namespaces.

14. A system according to claim 13 wherein said namespaces are organized by a logical name.

15. A system according to claim 10 further comprising a database server connected to said client applications, wherein said client applications uses said property settings in connecting to said database server.

12. A system comprising:

one or more processors;

a plurality of client applications executing in said one or more processors;

a property repository storing property settings for a plurality of said client applications;

a property service for transferring property settings between said client applications and said property repository; and

a plurality of property agents, each associated with one of said client applications, for sending pull-up requests to said property service to update said property repository, wherein said property service sends push-down events with updated property settings to selected ones of said property agents, wherein sending said updated property settings from said property service comprises sending a push-down event with said updated property settings to selected ones of said property agents that listen to a namespace.

16. A computer program product for the administration of client side property settings, said computer program product comprising:

a computer readable medium included in a storage unit, said computer readable medium having computer readable program code embodied therewith, said computer readable program code configured to;

establish communication between a plurality of property agents and a property service;

look up an identifier in a property repository for each property agent, wherein said identifier is a namespace;

modify a property setting in an updated client application associated with a selected one of said property agents;

send changed property settings from said selected one of said property agents to said property service;

update property settings associated with said updated client application in said property repository;

send said updated property settings from said property service to a plurality of property agents, wherein sending said property settings from said property service comprises sending a push-down event with said updated property settings to selected ones of said property agents that listen to said namespace; and

use said property agents to merge said updated property settings into an associated application.

17. A computer program product according to claim 16 wherein said computer readable program code is further configured to use said updated property settings to connect said client applications to a respective database server.

18. A computer program product according to claim 17 wherein said computer readable program code is further configured to send changed property settings under a logical name as a pull-up request to said property service.

19. A computer program product according to claim 18 wherein said computer readable program code is further configured to look up said namespace in said property repository based on said logical name.

20. A system, comprising:

one or more memory;

one or more processors coupled to the one or more memory, wherein the one or more processors perform operations, the operations comprising;

establishing communication between a plurality of property agents and a property service;

looking up an identifier in a property repository for each property agent, wherein said identifier is a namespace;
