Abstract

A system and method for efficient data access are described. A method for efficient remote data access for use by server management applications, includes transferring server schema from a service processor on a server to an application machine, receiving a request for server data on application machine, processing the request for server data on application machine, and forming, in a self-describing format, a single, consolidated query to obtain information not obtained from the server schema on the application machine. Processing the request obtains server data from the server schema on the application machine and the consolidated query is formatted in self-describing format. The method further includes transferring the consolidated query to the service processor, the service processor: processing the consolidated query, obtaining the requested data, and forming a response with the requested data in the self-describing format. The method transmits the formatted, retrieved data to application machine.

Claims

1. A method for efficient data access for use by server management applications, comprising:

transferring a schema from a service processor to an application machine, wherein the schema is a description of all the data the service processor can supply, how the data is organized, what data may be read only and what data may be written and the format of each data item;

receiving a request for server data on an application machine;

processing the request for server data on the application machine, wherein processing the request obtains data from the server schema on the application machine;

forming, in a self-describing format, a consolidated query to obtain information not in the transferred schema; and

transferring the consolidated query to the service processor.

2. The method of claim 1 further comprising the service processor:

processing the consolidated query;

obtaining the requested data; and

forming a response with the requested data in the self-describing format.

3. The method of claim 2 further comprising transmitting the retrieved data to application machine.

4. The method of claim 1 wherein transferring the server schema transfers schema identifier to application machine.

5. The method of claim 4 further comprising:

embedding the schema identifier into consolidated query;

the service processor receiving and comparing schema identifier to current version of server schema; and

if server schema is updated, transferring an updated schema to application machine.

6. The method of claim 5 further comprising re-forming the consolidated query using update database schema.

7. The method of claim 1, wherein the remote server management application receives and processes server database query and forms the consolidated query.

8. The method of claim 1;

further comprising storing static and fixed data from service processor in the server schema on the application machine.

9. A computer readable medium comprising instructions for:

transferring a schema from a service processor on a server to an application machine, wherein the schema is a description of all the data a service processor can supply to a server management application, how the data is organized, what data may be read only and what data may be written and the format of each data item;

receiving a request for server data on an application machine;

processing the request for server data on the application machine, wherein processing the request obtains data from the server schema on the application machine;

forming, in a self-describing format, a consolidated query to obtain information not obtained from the schema on the application machine; and

transferring the consolidated query to the service processor.

10. The computer readable medium of claim 9 further comprising instructions for the service processor

processing the consolidated query;

obtaining the requested data; and

forming a response with the requested data in the self-describing format.

11. The computer readable medium of claim 9 further comprising instructions for transmitting the retrieved data to application machine.

12. The computer readable medium of claim 9 wherein transferring the server schema transfers schema identifier to application machine.

13. The computer readable medium of claim 12 further comprising instructions for embedding the schema identifier into consolidated query;

the service processor receiving and comparing schema identifier to current version of server schema; and

if server schema is updated, transferring an updated schema to application machine.

14. The computer readable medium of claim 13 further comprising instructions for re-forming the consolidated query using update database schema.

17. The computer readable medium of claim 9 wherein the remote server management application receives and processes server database query and forms the consolidated query.

15. The computer readable medium of claim 9 further comprising instructions for storing static and fixed data from service processor in the server schema on the application machine.

16. A system for efficient remote data access, comprising:

an application machine, including;

a memory that includes a remote server management application and instructions for

transferring a schema from a service processor on a server to an application machine, wherein the schema is a description of all the data a service processor can supply to a server management application, how the data is organized, what data may be read only and what data may be written and the format of each data item;

receiving a request for server data on an application machine;

processing the request for server data on the application machine, wherein processing the request obtains data from the server schema on the application machine;

forming, in a self-describing format, a consolidated query to obtain information not obtained from the schema on the application machine; and

transferring the consolidated query to the service processor; and

a processor for executing the remote server management application and the instructions;

a server, including;

the service processor for receiving and processing the consolidated query from the application machine; and

a network connection between the application machine and the service processor, over which a copy of schema, consolidated queries, and retrieved data are transferred between application machine and server.
