Abstract

The present invention is directed to a system and method for managing resources in an information handling system. The present invention provides a "one stop" local area network (LAN) based registration tool that provides a common set of user and administrative functions. The goal of the present invention is to give the end user the responsibility of managing her own resources. One aspect of the present invention is a method for managing resources in a distributed computing environment. Another aspect of the present invention is a client/server, object oriented, distributed computing product (DCE) based tool, with application agents being used to manage individual services. The present invention receives client requests for resources from an application. These resources may include a password to obtain access to the application or to resources controlled by the application. Rules are checked to determine if prior approval is needed to process the request. If it is necessary to obtain approvals, including IDs on other systems, these approvals are obtained. Next, the resource request is sent to an application agent for processing. The application agent processes the requests, and then the rules are checked again to determine if notifications have to be sent (for example, to the requestor'"'"'s manager). Any required notifications are then sent.

Claims

1. A method of managing computing resources in a distributed computing environment, comprising the steps of:

receiving one or more requests from a client to access one or more of the computing resources;

checking one or more rules in response to receipt of the one or more resource requests to determine that one or more approvals are needed from a system of the distributed computing environment to grant access to a requested computing resource;

obtaining said one or more approvals needed to process the one or more resource requests automatically in response to said checking step determining that one or more approvals are needed;

sending the one or more resource requests to an application agent for processing, after obtaining the necessary approval;

processing, by the application agent, to provide one or more resources as specified by the one or more resource requests;

checking the one or more rules to determine if one or more notifications need to be sent; and

notifying one or more users that the one or more resource requests have been processed.

2. A method of managing resources according to claim 1, further comprising the step of logging one or more states associated with the resource request in an audit log.

3. A method of managing resources according to claim 1, further comprising the step of initializing a server for receiving client requests.

4. A method of managing resources according to claim 3, wherein said step of initializing a server comprises the steps of:

reading a configuration file;

initializing the server according to one or more values read from the configuration file;

registering the server in a distributed computing environment namespace;

spawning a thread to execute a task processor for the server;

obtaining a list of one or more available applications; and

waiting to receive client requests.

5. A method for managing resources according to claim 4, further comprising the steps of:

reading a service request queue; and

placing one or more resource requests in the service request queue into an execution queue.

6. A method for managing resources according to claim 1, wherein said step of sending the resource request to an application agent for processing comprises the steps of:

polling an execution queue;

taking a request off the execution queue;

obtaining data regarding the resource request from a service request queue;

checking a status of the resource request; and

if the resource request is in a ready state, calling the application agent to process the resource request.

7. A method for managing resources according to claim 6, further comprising the steps of:

waiting for a return code from the application agent; and

updating the status of the resource request in the service request queue.

8. A method for managing resources according to claim 1, further comprising the step of adding a new application, along with an associated application agent, to the distributed computing environment.

9. A method for managing resources according to claim 8, wherein said step of adding a new application, along with an associated application agent, comprises the steps of:

identifying the new application to the server;

identifying one or more tasks supported by the new application; and

setting one or more rules for each of the one or more tasks supported by the new application.

10. An apparatus for managing computing resources in a distributed computing environment, comprising:

one or more clients;

at least one server;

one or more application programs, each having an associated application agent;

a master object for communicating between the server and the application agents;

means for receiving one or more requests from a client to access one or more of the computing resources;

means for checking a rules table in response to receipt of the one or more resource requests to determine that one or more approvals are needed from a system of the distributed computing environment to grant access to a requested computing resource;

means for obtaining said one or more approvals needed to process the one or more resource requests automatically in response to said checking means determining that one or more approvals are needed;

means for sending the one or more resource requests, via the master object, to an application agent for processing, after obtaining the necessary approval;

means for processing, by the application agent, to provide one or more resources as specified by the one or more resource requests;

means for checking the rules table to determine if one or more notifications need to be sent; and

means for notifying one or more users that the one or more resource requests have been processed.

11. An apparatus according to claim 10, further comprising:

an audit log; and

means for logging one or more states associated with the resource request in the audit log.
