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:

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

receiving a request for server data at the application machine;

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

the application machine forming, in a self-describing format, a consolidated query using the schema to obtain information not in the schema;

sending the consolidated query to the service processor; and

receiving an updated schema at the application machine, where the updated schema was updated by the service processor in response to information in the consolidated query indicating that a version of the schema at the application machine is not up-to-date.

2. The method of claim 1, wherein sending the consolidated query to the service processor causes the service processor to:

process the consolidated query;

obtain data requested by the consolidated query; and

form a response with the obtained data in the self-describing format.

3. The method of claim 2 further comprising receiving, by the application machine, the obtained data transmitted by the service processor.

4. The method of claim 1 wherein receiving the schema comprises receiving a schema identifier at the application machine.

5. The method of claim 4 further comprising:

embedding the schema identifier into the consolidated query;

wherein the updated schema was updated by the service processor in response to the embedded schema identifier indicating that a version of the schema at the application machine is not up-to-date.

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

7. The method of claim 1, wherein the receiving the request, processing the request, and forming the consolidated query are performed by a remote server management application at the application machine.

8. The method of claim 1, further comprising storing static and fixed data from the service processor in the schema at the application machine.

9. A non-transitory computer readable storage medium storing instructions that upon execution cause an application machine to:

receive a schema from a service processor on a server,

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

receive a request for server data;

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

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

send the consolidated query to the service processor; and

receive an updated schema, where the updated schema was updated by the service processor in response to information in the consolidated query indicating that a version of the schema at the application machine is not up-to-date.

10. The computer readable storage medium of claim 9, wherein sending the consolidated query causes the service processor to:

process the consolidated query;

obtain data requested by the consolidated query; and

form a response with the obtained data in the self-describing format.

11. The computer readable storage medium of claim 10, wherein the instructions upon execution cause the application machine to receive the obtained data.

12. The computer readable storage medium of claim 9, wherein the instructions upon execution cause the application machine to store static and fixed data from the service processor in the schema at the application machine.

13. The computer readable storage medium of claim 9, wherein the information in the consolidated query includes a schema identifier embedded in the consolidated query.

14. A non-transitory computer readable storage medium storing instructions that upon execution cause an application machine to:

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

receive a request for server data;

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

form, in a self-describing format, a consolidated query using the schema to obtain information not obtained from the schema on the application machine, wherein the schema identifier is embedded into the consolidated query;

send the consolidated query to the service processor; and

receive an updated schema at the application machine, where the updated schema was updated by the service processor in response to the embedded schema identifier indicating that a version of the schema at the application machine is not up-to-date.

15. The computer readable storage medium of claim 14 further comprising instructions for re-forming the consolidated query using the updated schema.

16. A server comprising:

a service processor; and

a memory to store a schema that includes a description of data the service processor is able to supply to a server management application at an application machine, how the data is organized, what data is read only and what data may be written, and a format of each data item in the data,

wherein the service processor is configured to;

send the schema to the application machine over a network,

receive a consolidated query formed by the application machine using the sent schema, wherein the consolidated query is formed by the application machine in response to a request for server data received at the application machine, and the consolidated query is to obtain information not found in the sent schema,

send requested data to the application machine in response to the consolidated query;

determine whether the schema at the application machine is up-to-date based on information in the consolidated query, and

send an updated schema to the application machine in response to determining that the schema at the application machine is not up-to-date.

17. The server of claim 16, wherein the service processor is configured to further:

retrieve a schema identifier included in the consolidated query, wherein the information in the consolidated query includes the schema identifier,

wherein determining whether the schema at the application machine is up-to-date is based on the schema identifier.
