Abstract

A network of grid managers includes a first computer linked to a second computer, the first computer having a first grid manager and the second computer having a second grid manager, the first and second grid managers handling at least locating, reserving, allocating, monitoring, and deallocating one or more computational resources for an application, the grid manager, upon receipt of a command, loads new instructions to modify current instructions residing in the service that modifies a behavior of the service without restarting the service.

Claims

1. A network comprising:

a first computer linked to a second computer, the first computer having a first service and the second computer having a second service, the first and second services handling at least locating, reserving, allocating, monitoring, and deallocating one or more computational resources for an application, the service, upon receipt of a command, loads new instructions to modify current instructions residing in the service that modifies a behavior of the service without restarting the service.

2. The network of claim 1 wherein the command causes a modification of a behavior of the application without restarting the application.

3. A method comprising:

receiving a message having a command for a service that handles locating, reserving, allocating, monitoring, and deallocating one or more computational resources for an application running on a computer in a network;

loading a first set of instructions from a location remote from the service in response to the command;

replacing a portion of instructions for the service with the first set of instructions; and

executing the service according to the first set of instructions.

4. The method of claim 3 further comprising replacing a portion of instructions for the application with the first set of instructions and executing the application according to the first set of instructions.

5. The method of claim 3 further comprising:

modifying a relationship between the service and a second service in response to the command, wherein the second service comprises locating, reserving, allocating, monitoring, and deallocating one or more computational resources for an application running on a computer in the network.

6. A computer program product, the computer program product being operable to cause a data processing apparatus to:

receive a message having a command for a service comprises locating, reserving, allocating, monitoring, and deallocating one or more computational resources for an application running on a computer in a network;

load a first set of instructions from a location remote from the service in response to the command;

replace a portion of instructions for the service with the first set of instructions; and

execute the service according to the first set of instructions.

7. The computer program product of claim 6 wherein the computer program product is further operable to cause a data processing apparatus to replace a portion of instructions for the application with the first set of instructions and execute the application according to the first set of instructions.

8. The computer program product of claim 6 wherein the computer program product is further operable to cause a data processing apparatus to modify a relationship between the service and a second service in response to the command, wherein the second service comprises locating, reserving, allocating, monitoring, and deallocating one or more computational resources for an application running on a second computer in the network.
