Abstract

Methods, systems, and computer program products for editing configuration data such that alterations in one representation of the configuration data are reflected in one or more other representations of the configuration data. The altered configuration data may take effect without having to restart a corresponding program module. Multiple alterations to the configuration data may be consolidated. A differencing operation may be used to identify an altered portion of the configuration data. For one or more altered portions, an “updategram” may be generated and used to update a multiple program modules at various interconnected computer systems. A history of alterations to configuration data also may be maintained, making it possible to revert to an earlier version of the configuration data. Erroneous data may be ignored. Access to updated representations of the configuration data may be provided at a configuration management interface.

Claims

1. A computing system executing one or more program modules that operate in accordance with configuration data, wherein the configuration data is used during initialization of the one or more program modules, the computing system comprising:

one or more computer-readable storage media having computer-executable instructions for implementing a method of editing the configuration data such that changes made to one representation of the configuration data are reflected in one or more other representations of the configuration data, thereby keeping each of multiple representations of the configuration data current, the method comprising;

defining an update time period during which any alterations made to a non-persistent in-memory representation of the configuration data are deferred from being propagated to a persistent file representation of the configuration data;

receiving multiple alterations to the non-persistent in-memory representation of the configuration data during the update time period;

after the update time period has elapsed, comparing the number of alterations that were made to the non-persistent in-memory representation of the configuration data during the update time period to an alteration threshold;

upon determining that the number of alterations is less than the alteration threshold, updating the persistent file representation of the configuration data to reflect all the alterations that were made to the non-persistent in-memory representation of the configuration data during the update time period; and

upon determining that the number of alterations is more than the threshold, deferring the updating of the persistent file representation of the configuration data for at least an additional update time period.

2. A computing system as recited in claim 1, wherein the one or more program modules operate in accordance with the altered in-memory representation of the configuration data without having to be restarted.

3. A computing system as recited in claim 1, wherein a software interface is used to make multiple alterations to the in-memory representation of the configuration data at distinct times.

4. A computing system as recited in claim 3, wherein the method further comprises an act of defining a deferral threshold, such that when the number of consecutive deferrals reaches the deferral threshold, updating the file representation of the configuration data cannot be deferred for another update time period.

5. A computing system as recited in claim 1, wherein the method further comprises:

using a differencing operation to identify an altered portion of the file representation of the configuration data; and

updating the in-memory representation of the configuration data with only the altered portion of the file representation of the configuration file that is identified by the differencing operation.

6. A computing system as recited in claim 5, wherein the method further comprises an act of storing one or more altered portions of the file representation of the configuration data that are identified in one or more differencing operations as a history of alterations to the file representation of the configuration data.

7. A computing system as recited in claim 6, wherein a later altered portion of the file representation of the configuration data, corresponding to a later differencing operation, contains erroneous configuration data, and wherein the method further comprises an act of ignoring the later altered portion.

8. A computing system as recited in claim 1, wherein at least one of the in-memory representation of the configuration data and the file representation of the configuration data is structured in accordance with an eXtensible Markup Language (“

XML”

) schema.

9. A computing system as recited in claim 5, wherein the file representation is altered via at least one of a text editor or a software interface.

10. A computing system as recited in claim 1, wherein the method further comprises an act of exporting the updated in-memory representation of the configuration data to a configuration management interface.

11. A computing system as recited in claim 1, wherein the method further comprises an act of exporting either the file representation or in-memory representation of the configuration data for subsequent importing by some computer system.

19. A computing system as recited in claim 3, wherein the software interface is a object-oriented Component Object model interface.

12. A computing system executing one or more program modules that operate in accordance with configuration data, the computing system comprising:

one or more computer-readable storage media having computer-executable instructions for implementing a method of editing the configuration data such that changes made to one representation of the configuration data are reflected in one or more other representations of the configuration data, thereby keeping each of multiple representations of the configuration data current, the method comprising;

altering an in-memory representation of the configuration data, wherein altering the in-memory representation includes making multiple alterations at distinct times during an update time period;

after the update time period has elapsed, determining a total number of alterations that includes the number of alterations that were made to the in-memory representation during the update time period and the number of alterations that were made during a previous update time period that were deferred from being propagated to a persistent file representation of the configuration data;

comparing the total number of alterations to an alteration threshold;

upon determining that the total number of alterations is less than the alteration threshold, updating the persistent file representation of the configuration data to reflect all the alterations that were made to the non-persistent in-memory representation of the configuration data during the update time period; and

upon determining that the total number of alterations is more than the threshold, determining the maximum number of update time periods that at least some of the alterations have been deferred such that if at least some of the alterations have been deferred for a number of update time periods that exceeds a deferment threshold, the persistent file representation of the configuration data is updated to reflect all the alterations, whereas if none of the alterations have been deferred for a number of update time periods that exceeds the deferment threshold, the update of the persistent file representation with the alterations is deferred for at least an additional update time period.

13. A computing system as recited in claim 12, wherein the one or more program modules operate in accordance with the altered in-memory representation of the configuration data without having to be restarted.

14. A computing system as recited in claim 12, wherein the software interface is used to make multiple alterations to the in-memory representation of the configuration data at distinct times, and wherein the method further comprises a step for consolidating two or more alterations to the in-memory representation of the configuration data that occur during an update time period into a single update of the file representation of the configuration data.

15. A computing system as recited in claim 12, wherein the method further comprises a step for maintaining a history of alterations to the file representation of the configuration data.

16. A computing system as recited in claim 15, wherein the history of alterations defines one or more versions of the file representation of the configuration data, and wherein the file representation of the configuration data contains erroneous data, and wherein the method further comprises an act of:

(i) ignoring the erroneous data, or (ii) reverting to an earlier version of the file representation of the configuration data if one exists.

17. A computing system as recited in claim 12, wherein at least one of the in-memory representation of the configuration data and the file representation of the configuration data is structured in accordance with an eXtensible Markup Language (“

XML”

) schema, and wherein the XML schema allows for custom configuration data for one or more data elements at one or more specific locations within the configuration data that are not otherwise represented in the XML schema.

18. A computing system as recited in claim 12, wherein the method further comprises a step for providing access to one or more updated in-memory representations of the configuration data at a configuration management interface.
