Abstract

A network domain includes a plurality of agents and a domain server, the domain server operable for automatically transmitting messages to the agents to reset the agents upon the occurrence of a critical event. Upon receipt of a restart command, each agent terminates executing processes and then restarts processes.

Claims

1. A method for automatically resetting agents in a domain upon a critical event comprising:

receiving notice of a critical event;

obtaining an IP address of each agent in the domain;

transmitting a restart command to the IP address of each agent;

upon receipt of the restart command, terminating executing processes on each agent; and

upon termination of all processes on an agent, restarting processes on the agent.

2. The method of claim 1, wherein transmitting the restart command to the IP address of each agent comprises transmitting the restart command sequentially to the IP addresses of the agents.

3. A method for automatically resetting agents in a domain upon a critical event, the domain including a domain server, the method comprising:

receiving notice of a critical event;

establishing a connection with an agent server;

determining whether the agent server is the domain server;

if the agent server is not the domain server, obtaining the IP address of the domain server and transmitting a domain restart command to the domain server;

obtaining an IP address of each agent in the domain;

transmitting a restart command from domain server to the IP address of each agent;

upon receipt by an agent of the restart command, terminating executing processes on the agent; and

upon termination of all processes on the agent, restarting processes on the agent.

4. The method of claim 3, wherein transmitting the restart command to the IP address of each agent comprises transmitting the restart command sequentially to the IP addresses of the agents.

5. A computer-readable storage medium containing computer-executable instructions for:

obtaining the IP address of each agent in a domain; and

transmitting a restart command to the IP address of each agent;

the restart command initiating instructions executable by an agent to;

terminate executing processes on the agent; and

upon termination of all processes on the agent, restart processes on the agent.

6. The storage medium of claim 5, wherein transmitting restart command to the IP address of each agent comprises transmitting the restart command sequentially to the IP addresses of the agents.

7. A network domain, comprising:

a plurality of agents; and

a domain server comprising a processor operable to execute instructions for;

obtaining an IP address of each agent in domain; and

transmitting a restart command to the IP address of each agent;

the restart command initiating instructions executable by an agent to;

terminate executing processes on the agent; and

upon termination of all processes on the agent, restart processes on the agent.

8. The network domain of claim 7, wherein the instructions to transmit restart command to the IP address of each agent comprises instructions to transmit restart command sequentially to the IP addresses of the agents.

9. A domain server for a network having a plurality of agents, the domain server comprising:

a processor operable to execute instructions for;

obtaining an IP address of each agent in domain; and

transmitting a restart command to the IP address of each agent;

the restart command initiating instructions executable by an agent to;

terminate executing processes on the agent; and

upon termination of all processes on the agent, restart processes on the agent.

10. The domain server of claim 9, wherein the instructions to transmit restart command to the IP address of each agent comprises instructions to transmit restart command sequentially to the IP addresses of the agents.
